UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust kzfaq.infoUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.

It's nice to listen to a guy who really understands how these machines work. I've replaced a few pumps, and carburetors in my 34 years as a painter. Thanks for the detailed explanation, great job!!

What a great video. Everyone who owns a pressure washer and isn’t rich should be required to watch this. Excellent job. Very good.

Thanks for the great video. I volunteer at the St John's tool Library in St John's Newfoundland. Your videos help us repair good but non-working donated equipment. We are non-profit organization operated entirely by volunteers. We can't afford to buy new equipment but we love to recycle. Thank you so much for your help.

Best video ever, precise and clear explanations along the video. Easy to keep track of procedures, and process all the way through. Can’t wait for next one.

THANK YOU SIR!!! This has to be the BEST video I've found so far!!! You gave me a better understanding of what each part's function is along w/ what causes different failures! I've got a General Pump T1011 that lost pressure shortly after I effed up. Shut off motor & water to move washer, then fired it up & idled for a few minutes while I did a few things then wound it up to start washing. Gun was probably 50 ft away & when I pulled trigger got nothing...my dumb ass never turned water valve back on! Anywhooters, got it back on ASAP & it worked fine for a bit but after idling again to move a vehicle it decided it wasn't feeling it any more & said "EFF U DUDE I QUIT"! 😁 I'm not afraid to tear into it but been struggling to find accurate teardowns that match mine exactly...pump & unloader (K5) & until now I hadn't even gotten a thorough video explanation so I could diag it & fix it myself w/ minimal cost. I inherited it from my 90 yr old G'pa last year cuz he decided he was gettin tired & it's a good money maker as long as I'm not starting the season going too far in debt!!! So thanks again for sharing knowledge & explaining HOW components works & not just acting like I know everything you do. If I did I wouldn't be here! Thanks again! YOU TAUGHT ME TO FISH & DIDN'T JUST FEED ME FISH FOR SUPPER! 👍 And YES, I'm bored & can BS forever. Hope you enjoyed my novel...✌ P.S. Subbed & checked you're info & found something cool. You joined March 26th 2010 & that was a BIG day for me...because at 6:15 & 6:16 PM My twin 👶boys👶 joined the world!!! I'll take that as the vibe that led me your way & why I was moved enough to write a novel in response to your video! Leland & Landon by the way...and they're pricy cuz, TWO TIMES TWO TIMES, so fix washer-make the doughnuts-blow money on boys!!!

Thanks man this is the absolute best video I've seen on pressure washer pumps ,unloader valves, when to repair, what to look for. really appreciate it

Thanks, you answered several of my questions. This is how videos should be made. Clear & concise.

#1 Pressure Washer Repair video on KZfaq. Thank you!!!

Nice job on this video! I was always curious how my PW pump worked, now I know. This all started trying to figure out why my pump wasn't drawing soap/chemical solution. Thank you very much.

This is my kind of video. Straight forward, zero bullshit. Thank you!

Found the prob - 3 of those valves were messed from little plastic fragments. I kept it in a storage place that freezes in the winter. Ordering a new set of valves. Thank you!

There’s no one on the internet like you Bryan, so much knowledge, experience and willingness to share and teach. Thank you!!

You should have been a teacher this is the most informative video on KZfaq

Great video! I feel more comfortable tackling a future pump project after seeing your video. Thank you for sharing your knowledge!

Best information and most useful I have heard after watching 5 other videos before it. THANK YOU!!!!

Great video! Very well explained! I am a DIY guy but new to pressure washers. This video makes me feel comfortable diagnosing and trying to fix a used unit I picked up. Thank you!

I've worked on a lot of things Brian but had no experience at all with pressure washers. So thank you for the very informative video. Excellent camera work and audio quality along with the great explanation. A tough combination to find on KZfaq videos! Attaboy!

Thank you Very much 'Brian'' You have a way to 'capture our attention' in the way you explain everything so clearly and is understandable for most anybody who as interest in learning the (abc) of 'pressure washing' machinery... (Like some other 'commentator said' !! YOU (Should/Could) have been a VERY GOOD TEACHER !!! Thanks again, The common 'KZfaq' followers are very lucky to have someone like you to show and teach us 'Your knowledge'...👌👍👏

Thanks for the video.I have two old pressure washers in the pole barn.Never new exactly what the problem was with them.Probably won't fix them but I am going to tear them apart to just see what the problem is.Thanks.

Thanks for the very prompt and informative video. Just sent my commercial unit in to our shop because of no pressure. Now I know what to look for and diagnose the situation. 👍

The most informative video I've watched to date on small engine related product , clear , concise and no nonsense, here in Southern Africa we battle to get quality service and repair and top notch knowledge, Very much appreciated.

Good video! Didn’t exactly answer what I was hoping to see but it was so informative I finished the video anyway. 😂

Just wanted to say I appreciate your video. I picked up a used electric unit and used this video to help diagnose it.

Thank you, thank you thank you. This was very well explained and broken down so anyone can understand it. I appreciate what you did. Thank you very much.

Thank you for a no nonsense video. Subscribed.

Thanks so much for the engine piston, crank, intake etc, anology. Great vid!

I viewed this video because I am considering purchasing a used pressure washer. Your in depth analysis gives me an idea of what to look for like milky oil and lower outgoing water pressure than what machine is designed. Thank you for your easy to understand explanations.

Excellent. You are a born teacher and accomplished technician. Thank you.

Thank you! This was very helpful!

I know im getting old when stuff like this have me entertained.. i feel like a pro now working on my machine thanks

Excellent explanation of how the pump works, Now I m sure I know my problem of water in my pump oil. Thanks for a great tutorial and the breakdown to show the insides of the pump and how they work. Big Thumbs up. Any links to pump kits would be great.

Thank you man! great video! So helpful and gonna save me a bunch of money!

Beautiful job on that PW 101 video. I got to learn a lot. My Husky PW did not build enough pressure anymore so changed the entire pump and the entire spraying wand (gun). Unfortunately this didn't make any difference and pressure is still not building at all (Honda engine is working fine). Any idea what the problem may be? Could it be the quick connect fittings that are leaking air or something?

Very Good Video Brian!!!

Great video, great explanations, overall amazing video!

Hey Brian, thank you for the video. I have an older BE Power washer with a 2200psi Honda. I have a significant leak in the pump, before watching the video I took the housing apart and looks like one of the ceramic pistons is damaged. Would that be the source of the leak?

I just dumped my pumps oil..... it was like spoiled clumpy milk 😂.... thank you for your service to the DIY community 😆

Nice video, good technical info, and not overly explained! I have a (discontinued) karcher g4000rh (4000psi 3.4gpm) itʻs leaking oil. what would you recommend as a good replacement pump for it?

Super helpful, Thanks!

he makes a lot of good points here but in any case of something not working the way it should, always think simple before you get into complicated repairs. I have the exact same Honda motor and pump (Comet Pump). Suddenly no water was making it to the wand where it quick connects to the pump..so , I undid the quick connect from the pump body and low and behold, a piece of rubber had broken away from one of the seals and was completely blocking the exit hole to the hose coupling . Once I cleared the obstructing, good as new

You mentioned that the pressure washers that are sold at Home Depot or Loews it doesn’t pay to repair,but the thing is it’s actually the unloader valve itself that’s an easy fix.Many people are being sold an entire pump assembly when they only needed to clean and oil the unloader valve.This is when you pull the trigger and kicks off after just 3 seconds.This is a common issue many are having.Thank you for sharing your tips and advice.

Fantastic video. You translated giberish to basic English. By far the best video on a pump breakdown. I have a question... Honda gx390 with a CAT 66DX40G1. One of my techs called me and said the engine blew a rod or something because there's a hold in the engine and chunks of the engine flew out. No injuries thankfully. I know that low or no oil can usually cause this so I just purchased another gx390 and am currently swapping it out with the blown engine. I decided to clean the shaft, key, and after coming across your video decided to clean a little more. Something I noticed when cleaning the shaft and key slot....pieces of greasy grass were lodged in there so I was able to clear out what I could see. A couple months ago, this pwasher tipped over while a tech was washing a long walkway. He turned it back up right, white smoke everywhere, small grass fire extinguished. Engine would not restart. Took it to the warehouse, changed all the fluids and spark plug and got it up running again. Then the blown engine incident happened. Is it possible that grass got logged into the pump during the tip over? Is this possibly what blew the engine because the dip stick showed some oil on it when I checked it. I can't see well enough inside the hole that got blown open to see if any oil was in there. This is an older model CAT pump and I'm having trouble removing a few of the tork bolts that hold the head in place, they keep stripping so I found it best to Stop. I'm eager to go ahead and install the pump to the new engine BUT am hesitant to do so in case I didn't get all of the grass out. I've used an air compressor to blow air through all openings (water supply, shaft,unloader, etc. Your thoughts about me moving forward without certainty that all of the grass has been removed (assuming that may have lead to the blown engine). Thank you in advance. We have a 9 - 4 story condo project to start in 6 hours (7:30am CST) and believe it or not the 4gpm wheeled units work better than our 10gpm trailer and flatbed units since we are able to just load the 4000/4 into the 60' man lift basket. This is Phase 2 of the project so we've already been through all the "do it this way" methods. Lol. KtPowerWashing.com

I just opened a small business with pressure washing. I watch a lot of videos every day in the evening about different things. Most videos are basically all the same. You broke that unloaded valve down to a science. Thanks for your help. I’ve been wondering if I should turn it to get -/+ pressure. But now I no. I also just ordered a pressure gauge, hose swivel , oil cut off & kill switch spark plugs and air filters. I’m gonna order a new pump cause I’ve had the same pump for 8 years. So was wondering if you will do a video on pump replacement. Thanks for taking time out to help people like me.

Great video and very informative. I cannibalized parts from different units. I added a pump from a unit where the motor went bad and added the pump to a Honda motor from another unit where the pump went bad. Now when I let go of the trigger, the unit cuts off immediately. I took the unloader valve out and the piston moves freely. The set nut was spinning freely and not depressed against the larger nut that holds the spring in place. The unit hops and skips more than I recall also. Do you have any suggestions? Thanks in advance for this instructional video.

Thank you very much for your prompt response and guidance.

Awesome video man, so helpful. Would you show a video of what oil side of the pump looks like?

Great! presentation great presentation liked the information i have a 1700 psi Ex cell pressure washer model number WGV1721 found the pressure washer in the trash brought it home and it worked fine but had a leaking spray gun, i tighten the spray gun halves and loss total pressure. I adjusted the uploader valve and still the pressure washer did not get built any pressure if you have any advise or any help, i would appreciate it.

Thanks I took some of this info and applied it finally got my pressure washer running 15 months after I got it for free lol

Hey great video, can you demonstrate how you’d measure the pressure and the flow rate on a unit ?

Accurate and helpful information.👍 We stock a full line of spare parts for this model pump - model 1506.5A

What a great video, you sure do have a way of explaining how pressure washers work, what kind of pump would you be replacing it with ? Maybe you can do a video installing the new pump and setting up the unloader, again thank you

Thanks. Good info, very helpful.

Great video, Thanks

Very helpul. Thanks Brian

brian, thanks for the class.

Great video! Two questions. 1. I'm shopping for a 4 GPM 4000 PSI washer. Pump options are AR, Cat, GP, and HP. Which to you recommend for long life and rebuildability? 2. I've read that using pump saver after every use extends the life of the unit. What's your opinion on using light machine oil or something to that effect instead of the product in a can?

Very nice explaination Brian. Thank you.

Such a great video ,,thank u 💪🏾💪🏾💪🏾

Great Video!!

Thank you. I learned a lot. But mainly to just buy a new one :)

I enjoyed your video keep up the good work. And thank you for making it.

*I just bought a Mi-T-M 3000 psi 3 gpm pump for my honda gc190 and I was told by someone to add a bypass hose on unloader to help with off trigger over heating. Would you say this is critical for me to do to make the pump last longer? The pump has 2 plugs where the hose would go so looks pretty simple to do, remove the 2 plugs and replace them with two 3/8 barbs and a foot or so of 3/8 hose. Thanks in advance.*

Brilliant explanation. Thank you.

Great video. Best explanation of parts and functions for the pump.

Thank's so much ,my steamer it's working now

Very informative. No bs. Good job.

Brian: Thank you for a great video. My pressure washer has the pressure gauge on the top of the head above the thermal valve (engine side). Do you think this is a poor place or should it be in line before hose? My pressure washer went from (Had unloader turned down to 2000#) turned it off to fix inlet water leak, started back up and only 150# of pressure. I tore it down to investigate and believe or not the ceramic pistons did show wear in about the same place on all three (AR pump). You are right it gets expensive quick beyond the seals, (Got milky oil) so I am going to buy a new pump and recycle the old one. It will have ceramic pistons for sure (Mine lasted 20+ years).

Brian, thanks for the video. I bought a pressure washer on a garage sale a few years back. Worked fine at the time, but now when I squeeze the handle I get good pressure for a split second and then lose it. Any ideas? I am not sure of the make or model of the power washer because all of the tags are gone, including the small sticker on the frame. I can see it said "Tahoe" but I can't see anything else. It looks identical to the pump/brass part in your video. How do I know what to search for when trying to find replacement parts? Thanks!

I appreciate your video. Thank you.

I have a 4 gpm with a general pump ez4040g pump. The other day I lost pressure. I took the unloader off and it seemed to be sticking. I cleaned it up and oiled it and it seems fine now. Do you think I should order a new unloader or is this a common problem? Thanks

Thanks for the video. That was really well explained.

Thanks Brain, it's nice to listen to English & a guy that knows what he's doing & explains all as he goes, damn good job buddy, Bet you're a$$ I'll be following you & probably asking u a few things, can I send you pictures of a pump I'm working on now?

Good night sir your information is gold Lawson in Trindad and Tobago 🇹🇹 thanks brother.

Brother you made my day with this video my 4200 is working at 2800 but of course at standstill goes to 4k

Hi Brian great video I have 3000psi w/ 8GPM Honda Gx690 pressure washer. I need to replace the unloader valve the unloader that's on the pump is a VRT3 however I can't fine one with 3000psi only 4500psi can I use the 4500psi unloader

Just ran into your channel, thanks for the video, I bought new 4gpm 4400 psi pressure washer that has a built in unloader valve, I just realize that I should get one that I could run a hose to my buffer tank to avoid damaging it when I’m not squeezing the trigger on the gun. What is my best option other than getting different pw to achieve that. Thanks again.

Great video, very well explained in details.

Hey Brian. Nice video. If you are still following, I have a leak on a unit I just bought used at the top bolt of the unloader. Bottom bolt looks good. Do I just back both bolts out to detach from the head? Is there a O-ring in there to replace or something?

Great video Brian! Question: What are the 3 vertical channels below the cylinders that are open to the bottom of the pump? I have a brand new machine and after about 8 uses I'm seeing a small amount of water come out of one of the channels.

Washer working then pressure quit, have Annovi REVERBERI rsv3g30 PUMP, no pressure. Took apart to clean /look for debris, flushed with water. Valves very hard to move or remove. (did not take out -options?). Put together still no pressure. Would replace unloader and valves be next step? Removed pump and checked pistons (good). Thanks

WOW GOOD VIDEO Thx Ed Loretto Ontario Canada

Thank you for. Insightful

Hi Brian Thanks for the video , I have a 4200 psi pressure washer that has a relatively unused pump on it that unfortunately through a lack of oil has broken three crank connecting rods, I have Strip down the pump all ceramic pistons valves and everything all look quite new , It is a Chinese pump so I’m not sure whether this makes a difference would I be able to replace the connecting rods or would I be better to just scrap it and buy a new pump what would be the best option, and if buying a new punp I would prefer to have the same 4200 psi what would you recommend as a flow rate as well

Brian, thats an awesome video, I have a question for you. How does water get into my crankcase from the actual pump? I pulled my oil plug on the honda engine and water shot out of it mixed with oil.

So do I have to take it all apart if there is no water flow at all? I have a fairly new dewalt pressure washer for my pool company and havnt used it in a few months and it was perfectly fine but a job came up and the water won't flow through the pump at all and I could not figure it out

Great video.. very clear and concise. Can you post some of the parts sources you mentioned? Thanks!

Brian, I rented a MiTM CA-2703-HDKB from Home Depot today. I had a pressure gauge from Northern Tool installed right after the regulator and with the trigger depressed the pressure washer stayed at 1900 psi. When I released the trigger pressure climbed to around 2700 psi, dropped down and then climbed and kept resetting every 10-15 seconds. There was no knob on the regulator. I wonder if Home Depot permanently sets the pressure so people don't chew up their houses. Do MiTM pressure washer allow you to run them to the factory spec? Will a 2700 psi industrial pressure washer run at 2700 psi? I've seen repairs on consumer pressure washers where manufacturers over rate their machines. Do the psi ratings for MiTm pressure washers hold true? For what it's worth, 1900 PSI and the 15 degree tip did an amazing job on my formerly green vinyl siding.

Great video, I appreciate your time and knowledge. I have a karcher 3000pro with a 9 hp Honda gx270 engine. For the life of me there is no numbers on the pump. The pump leaks water and oil. The oil is not milky. When I press the wand trigger, It takes a few seconds for the pressure washer to activate. Please advice.

Very detailed video thank u

I primed and started my pressure washer and then after 2 or 3 secs I lost water, didn't notice a kink in my hose, it took me like 5 secs to shutoff the pressure washer. Do you think I might have caused any damage? I would like to hear your recommendation. I did use the pressure washer normally after restoring the water flow. I have a 3200psi 2.8 triplex pump

Were you able to make a recommendation for a replacement pump, I had a 5.5 hp GX160 and AR 3.5g27 pump thx

Great video , i have the same pump but the video didn't solve my problem, my pump is spraying water out of the channel under the centre piston does this sound like a blown seal?

Thanks Brian for the video. Excellent. We have a brand new pressure washer 3200 we got at an auction. Half price. Motorworks awesome. Honda motor 200. We are getting a lot of water leakage. The leakage is coming from the pump area in the cylinder. Suspect someone must have left water in it and it froze.. not sure. When we turn the water on the pump leaks around those cylinders you are mentioned. It is a BE 3200 with a Honda 200. Could it be just a gasket? When we turn the water on it leaks pretty bad underneath just beyond the cylinder. We seem to still have decent pressure. Water pressure that is. Just wondering if you had any thoughts on this. Did I mention it is a BE 3200 pressure washer. Looks brand new.

Great video

Awesome video, very informative,....how can I diagnose an unloaded, so hopefully I have an easy quick least expensive fix to my no pressure situation?....same pump as your video, ive taken unloader apart to the point of removing adjustment knob and pulled stiff spring.....seems intact except for filthy rusty water, but no scale or rust on spring.....was going to just replace entire pump....should I?

Do you have a video of a, unloader valve for a 3400 psi , 4gpm ? I am looking for info , my washer has poor pressure. The unit is a craftsman, 11hp , briggs and Stratton, 3400psi, 4gpm. The unloader looks very much like the one in this video. Thanks for your videos.

Hello, thnx for the video. I do have a question or two for you. I have a generac p. washer that will run but eventually ( might be a day or a week ) the oil will fill with gas. Any ideas, I’ve changed the carb out but no change. Any help would be appreciated.

Do you know what fitting do I need in the inlet to connect my flexzilla garden hose to it

Great presentation, thank you. I bought a Chinese washer, three cylinder like this one here. It started surging in the pump, not the engine, so I undid the valve caps as you did and number three had brass filings in it. Silly me I didn’t take any pics but instead cleaned it out and restarted it.....no difference obviously. So as it was virtually new I contacted the supplier who told me to remove the pump and return it to be checked by a technician, which I did. He returned it saying the technician checked it and found no fault, so I reinstalled it and started it up again. The surging was still evident, and contacted the supplier again, who declined to help any further. So.....what happened to it, and can it be repaired or should I buy a new pump as you have recommended in this video. If I buy a knew pump are they interchangeable or will I need an adapter plate ? Looking forward to your advise, cheers Steve
