How to fix a pressure washer that has no pressure | Replacing the check valves on my pressure washer

After not using my pressure washer for many months, I found out it is not making any pressure. I need to replace the check valves inside the pressure washer pump. The hardest part of this repair is getting the check valves out of the pump. I used some EZ out bolt extractors and a drill bit to remove them.
Here's the video where I found out the pump isn't working. • How to rebuild a Marve...

I use a self tapping 1/4" bolt, ease it in till it grabs and take 2 screwdrivers pry under the bolt head and out she comes.

This got me thinking about how to repair my Subaru pressure washer, although I only needed to replace the O-rings and lube up the check-valves, make sure every component could rotate, back-and-forth on everything. And voila! everything works. Maybe if you were more gentle, and used more lube, you wouldn't have needed those replacement parts. Who knows, but knowledge was created here, so thanks.

I have bought 3 pressures washers over three years. Suspect for any washer is the aluminum/zinc die cast housing used, which is subject to corrosion and a frozen pump. I got one season out of the first two washers. Go to use it the next year and "ZERO". Lock up. Looking at the inlets there was corrosion all over the casting. Comes the third pressure washer. On the first two I used the flush and store system liquid through the pump and put it away for winter. That didn't work. Third washer, put hydraulic tool oil (4-5 table spoons) into the water inlet and ran the pump for about 10 seconds. It flushed out water and left an oil film in the pump. I have had this last pressure washer 3 years now and it starts up every year after winter. And the pressure is still strong. Frankly, I think these manufactures should be coating the die cast housings with corrosion resistant coating. I am a product engineer of 45 years, and designed automotive parts with corrosion resistant coatings to withstand freezing rain, heat, and road salts. I can tell you I never went back to the manufactures washers that only lasted one season. My current washer is a Sun Joe and it is holding up.....with the oil purge included.

Shut the gas off when you are finished using it. Allow it to run until it sputters and kills on its own! No more gas left in lines and carburetor, stops it from gooing up while not in use!

@jviews1 Ай бұрын

agree for any gas engine, but a pressure washer with water pressure on, and trigger off will burn out the plastic pump components. These gas engine pressure washers cannot run with out water moving. Planned death for certain. And the metal is so weak and corrosive, guaranteed more sales.

@jviews1 so run the water through the wand until the engine runs out of fuel and shut off.

i got an 80 dollar pressure washer, electric. Not the most powerful, not the biggest machine. When first soaking the area or the car and then using this washer, it works fine. Has been giving me some pleasure for like 5 years now. To be honest, if it breaks down, i buy myself a new one for 80 bucks. I can not for the life of me think of a reason why i should bother using any kind of liquid sjit to try and save the internal parts. Especially not with the electric ones, because all of em originate from China. The more expensive ones may have a bit better quality parts but still, they aint gonna last for ever. It is a miracle if they last longer than the warranty period, since most of what we can buy these days is made to last just a bit longer than the warranty period.

Went to use my power washer yesterday (Craftsman different model) and a stream of water was shooting straight up from unloader valve or soap siphon port(?) I assume it's a check valve issue as well. Pump worked but with less than normal total pressure. Where exactly did you find the pump schematic and parts to order?? Thanks for posting

Butane gas cools and shrinks the valves and blow the valves out with air

@randybeard6040 23 күн бұрын

Some Commercial Pumps use to have a Recirc. Valve that would allow Pump to always have water flowing through it to keep pump from Cavitating which causes pump to get too hot thus often destroying pump. When you Stop Spraying for just a moment, you need to turn off/stop motor--often your paper work-directions will tell the owner this...

@jimlamb5508 4 ай бұрын

Using a paint can opener works well removing the check valves, but you have to grind the sides off a bit. the Check valves are not very sturdy and will fail quickly if water is not keeping them cool.

If you get no pressure and it sprays a stream of water without the pump engaging, check the filter first. It is located on the water intake. Mine was 1/2 inch deep plugged with calcium.

The check valves maybe stuck from dried soap. If you’re going to have to extract them, I would suggest letting the manifold soak in water over night.

I had the same issue as you with my AR pump. Took the 3 check valves out on the side (high pressure side) and all three were blown apart into pieces. I ordered new check valves and replaced them after cleaning out all the plastic pieces that broke off and were stuck in the passages. Got it all put back together today and tested it out, but no water would come out at all. Ordered MFG part number and the parts went back together just fine but I can't figure out why the pump wouldn't work. I took it back apart again and the 3 valves on the side were twisted and broken again but no water was coming out. Any thoughts on what is causing the check valve rapid disassembly and blocking water from coming out at all?

@exiquter78412 10 ай бұрын

If it stalls when you release the trigger on the wand, then the unloaded (overpressure valve) is hung up and not recirculating water back to the inlet of the pump. That part is the large brass valve with the hex nut and center stud next to the valve caps on the side.

These pumps are total garbage. Homeowner special = shit!. Buy yourself a professional unit. I have a newer toro and its never worked right. I'm on my 2nd pump because the original one never worked. It would have pressure for a second or two then it would be just a weak stream so i replaced the pump and I'm having the same problem. Plenty of h2o pressure from the house and I've tried different hoses still no pressure. POS.
