All your videos are top notch! Thx for making them, you have saved me tons of money!!

Thank you for taking the time to post this video. Very helpful!!

Fantastic, informative demonstration, thank you Mark!

Thank you from Canada for your very informative videos.

Just recently upgraded pool pump to a variable speed and on completion was told that the air in the suction line would work itself out. Didn't happen. After watching your video I was able to isolate the loose connection. My only regret is that I didn't find this video sooner. Thank you!

Thank you so much. I just fixed my pool issues after this video!!!!!

Great video! It helped me locate where I had a leak coming from. Thank you

Siperb tips.. compelling clarity. Thank you Mark.

Wow this is great and very informative thanks Mark

Thanks a lot..i was able to detect the leak using your video and surely saved a couple of hundred dollars.

Thanks. Very educational, a lot of details and information

Great video. Very well explained. Thanks.

Keep up the great work. Love your videos!

Thank you for this video. We had our pool equipment replaced in 2021. Each summer I complain to the owner that water sprays from the piping every time I backwash and that the pump is weaker (suction in skimmer poor) after my first backwash. I’m ignored or get a shoulder shrug thinking I’m doing something wrong since I’m new to this game. Now I know it’s not me. Especially since I’ve been able to keep the pool water clear & close to perfect every season.

Excellent video, thanks for this!

superb explanation, u r a very good teacher

Thanks for sharing your knowledge.Thanks to you I saved on a expensive service call.👍

Absolutely great videos! Best on KZfaq ‘ thank you sir ! Very informative

Thanks for a very useful video!

Fantastic video.. Thank You!

Your video is certainly helpful 👍

Thank you, thank you! For 3 years now I couldn’t find the leak. I thought it was in the skimmer pipe. By watching your video, I have found my leak. Great video. It works!

thanks again Mark!

Grat video. Very helpful

Thanks for sharing....

Thanks - - I'd forgotten about the filter drain plugs!

Thank you

Good video, I get air bubbles sometimes because of something that I have floating in the pool got into the skimmer and it prevented some of the water going in. Most of the time if i remove the skimmer cap and remove whatever is in the basket and I can listen to the water escaping. If that doesn't work I'll backwash and usually it works..

thank you Mark! that must be it.. I melted my basket last season! ugh I know.. but that fitting still needs replace - thank you thank you! - old streamline hot tubs? reset button? cant find anywhere - has its own "boiler"? .. old lol

Excellent analysis. Top-notch. Thank you.

Great job. My pool pumps air back into the pool returns.

Good video

I tried unclogging skimmer from filter with bladder hose..it seemed to be dissolving so.e white powder but never finish unclogging and pool got full to the top..any advise?

Thanks!

There are several common things do like cut before you even mess with the pump: low water level, stuck weir door, debris in slimmer basket. In your demo pump the inlet pipe is too close to the 90 degree fitting. Manufacturer recommends a MINIMUM straight run of 5 times the pipe diameter on this piece

Have a hayward 0740 FLO valve. and water leaks from the control handle. Could this be why my pump basket drains over night? Thanks for your input. Great video. I also get air bubbles in the pump basket when pool pump is running.

My 10k pool Renovated 18 months ago is now starting this. I think the glue on the pvc was done incorrect. Will be 👀 investigate 🔬 ing

Great videos. I do have a question. With the drain line open ( I have a side wall drain line) there's no bubbles, but little suction from the skimmer. I'll close the drain line partially and get better suction from the skimmer. If I close the drain line completely, there's a lot of air in the pump and bubbles from jets. Would a leak be in my skimmer line? I have a Hayward sand filter for an in ground pool.

Thanks for this video- I have a question, my system does not have a drain line into the pump, only skimmer (I believe the previous owners sealed the bottom drain years ago). Any suggestions other than being able to turn on and off the drain/skimmer lines? Thank you!

Sometimes the first thing to do is check after backwashing, or vaccuming the pool when you start the pump motor you notice air bubbles in the pump. What I do on my filter is open the bolt on the backside of my glass globe that shows the clean progress and open it up until I hear air whooshing out. Wait until you get solid water, tighten it back down and my air bubbles are all gone. Works every time

Not sure if you can answer my question or not. The return on my above ground pool shows slight foaming. When I first opened the pool, it used to foam the entire pool, but after shocking it, there is a little foam and bubbles at the return, and it is no longer acccuninating foam. The water pressure reading on my Hayward DE earth filter reads between 8 and 10, so I know the pressure is good. I also cleaned and lubricated the O-ring on my pump's collar, and have no water leaks. A local pool store claims it could be from the power of water through the return, but am not certain because this is the first year this has occured. Do you think the foam and bubbles can be coming from an air leak, or from the power of the water coming from the return?

Very informative video. I get air when I run my variable speed pump at lower speeds. Is this normal?

What I did to find the reason bubbles in the pool I ran a stream of water from a hose on the fittings starting at the bottom my case was the ball valve knob was broken hold a steam of water on it when the air goes out of the pump there you go

Any advice for those type of valves once they get older and are very difficult to move or don't move at all? Can you remove the handle and lubricate the ball valve inside?

I have a slight amount of air entering the pool from one of the returns, but no air at all in the skimmer basket, which seems strange. What might be the cause? There are four return paths to the pool and this is just in one, most likely the first from the pump.

Grandma has a 40 year old pool "I'm guessing" that seems to blow bubbles at 2 returns. The pump has air in it all the time. I've checked everything in your video and can't find the leak. There are trees nearby and don't want to jump to conclusions but my guess is that a root split an elbow, coupling or something else apart. If I'm right how should I go about finding this leak? The drain seems to produce more air witch I think is odd. Should I buy or rent an endoscope? Thanks for your help.

I don't have any valves on my skimmer nor drain, they both go directly to the pump.

I know this vid is older and not sure if you’re answering questions but when I backwash or to waste the filter leaks from the collar and sight glass on a Hayward sand filter could this be where air is why

The water level in my pump basket goes down about an inch and a half after filling it to the top. Suggestions? I don't see any water leaking between the pump and the jandy valve.

So closing either drain or skimmer line throws my psi out of wack and doesn't provide the pump with enough water. Is there another way to test this or should i assume the leak is on the pump side?

hi..what if the leak is coming from the "under pressure pipes" and not from the "suction pipes",would that still cause air bubbles on the pump?

Hello Mark, great video. I have low pressure and replaced my impeller but noticed slight air bubbles in pump. I do have a small leak on the pump output pipe threads. Could this cause low pressure and air in pump?

Hi! I’m super nervous I have an underground issue after seeing this video. I have bubbles in my pump that go away when I close the skimmer valve. Could this be the valve or something above ground or am I looking at a much bigger issue?

When I turn my pump off I hear a hissing from the pump and it looses its prime very slowly. My husband brought the pump in the house last year and I am wondering if some parts dried out. I also was blind when I went to vacuum on waste and vacuumed on winter. I am praying that didn’t do damage. I also see air when I am running just the skimmer. But the bubbles go away when I have both the drain and skimmer open. No bubbles with just the main drain. I have so much trouble with this pool! I spend over 500 every year and many frustrating hours of work to try and get it useable. Just want to cry. No local pool people can figure it out. Believe me I have tried and tried and tried to get reliable help. Thank you for this video. I now know how to isolate the leak. Do you have any ideas for me to check first?

Great video. Are you able to help? I have a pump that keeps turning off after prime. I have tried everything. New pump. New breaker. New on/off switch. Lines blown out. Shaving cream on all joints looking for leak. Some bubbles when priming. After prime it shuts off. I have been working on the pool for a week and can not figure out the problem. Any advice?

Hello, please help. Air bubbles are appearing when I'm pulling off the skimmer and main evenly. If I pull off the main drain solely I don't have any bubbles. If I pull off the skimmer solely, I don't have any bubbles. But, if I pull off both drains, air appears in the line. Is there a solution to this?

I can’t figure my issue out at all. I’ve just had a skimmer replaced on my pool and as soon as I tried to prime it super sucks and fills the pump basket half way and then slows down. I’ve tried flushing the line, bought a new pump basket cover, turned off one of the two pressure valves (it’s the only way I can get pressure into the sand filter) tried to prime the pump 70 times, wrapped Teflon tape around the old suction fittings (I have no drain line), replaced a pressure opening in the pool (because it was a wide open pvc piece) with a fish eye. When my pressure starts to top out I have to release the air valve so my sand filter doesn’t explode, but then the pump sucks in like a hose that has just been turned on. I’ve tried the rag trick on both ends of the skimmer line (to no avail) and I have to get this pool blue or I’m going to lose my home owners insurance. Someone please help me. Edit: sand filter is brand new (clear rx 24) because the old skimmer had the filter inside the piping. This a fiberglass pool and it’s 40 years old, and is 12.2k gallons at 25gpm for the 8 hour run if I could get it to prime. FYI: Your website form is missing it’s security seal. It says, (security seals here). Someone forgot to actually add them.

Is it possible for air to be drawn in past the seal on the motor impeller shaft?

Great video. On our system, when the pump speed is low, more air is in the pump. If we turn up the speed, there is less. Is that a clue to the air leak location???

Hi, Mark. I used the bucket test and have determined that there is an obvious leak somewhere in my pool. It has been extremely hot here in Texas the past few weeks. So I fully understand the loss of some water is due to evaporation. More water is lost when I run the pump. There is no water loss, except from evaporation, when the pump is off. The water level is now 2 inches below the two skimmers. So now when I do run the pump, it is pulling water from the main drain only. Is my leak from the main drain (suction line) or is it from one of the pressure lines?

I have one question. I have found out that my skimmer line has leak. What should do next?

Hi, when i put mine on drain it seems there is an air leak. When I put it on half half it works perfectly The problem is that even when I turn it off or keep it on drain the water level stay the same after 24 hours so I am not sure where this air leak comes from if you can help please. Thank you

I hired a professional pool company to fix my suction side leaks. After he left I went out and discovered he had simply wrapped duct tape around the pvc joints next to the pump. It actually worked for awhile until the duct tape went bad from sunlight. Can I caulk the pvc joints to eliminate the small leaks?

How about aire bubble when only run the system through the filter? when I put it to circulation the pebble disappear.

can we do soap and water while motor is on to see air leak instead of having another person there turn the pump on and off?

😊😊

I don’t have a drain line on my pool. My line goes from skimmer to pump, to filter and the other line is the return line

I can't keep turning my pump off and on because most of the time it catches the air flow and the motor surges up to 3500 rpm. I can sometimes get past this by filling the pump with water and quickly putting the lid on and being lucky.

Our bubbles were caused by the vacuum cleaner after removed no more air

“It will be too late” not for me 😎 🏃‍♂️

I have got a leak in my pool. When I rum the pump air bubbles come from return lines in pool. But pump housing will be almost full of water. Now when I vacuum my pool through skimmer the pump vasket doesn't even fill halfway with water. But I'm losing about 200 gallons a day. With pump off. Vinyl inground pool

Loosing my mind trying to find my air leak

I wonder if you can help me. I have my pool for years without problems but this year, when I try vacuming, as soon as I put the plate in the skimmer, water in the pump goes down (it takes a few seconds) and there is no water getting in it. I have this filter (see below) and I was wondering if it can be the air vent inside the filter that would be misplaced. As it is quite a job to empty the sand filter that is why I am asking. www.royalswimmingpools.com/Super-clear-manual.pdf Also can plummer grease can be used as lubricant on pool parts like the rings? Thanks.
