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!
Siperb tips.. compelling clarity. Thank you Mark.
All your videos are top notch! Thx for making them, you have saved me tons of money!!
Thank you from Canada for your very informative videos.
Thank you for taking the time to post this video. Very helpful!!
Great video! It helped me locate where I had a leak coming from. Thank you
Wow this is great and very informative thanks Mark
Great video. Very well explained. Thanks.
Keep up the great work. Love your videos!
Thank you so much. I just fixed my pool issues after this video!!!!!
Excellent video, thanks for this!
Thanks. Very educational, a lot of details and information
superb explanation, u r a very good teacher
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.
Thanks a lot..i was able to detect the leak using your video and surely saved a couple of hundred dollars.
Fantastic video.. Thank You!
Thanks for a very useful video!
Thanks for sharing your knowledge.Thanks to you I saved on a expensive service call.👍
Thanks - - I'd forgotten about the filter drain plugs!
Your video is certainly helpful 👍
Thanks for sharing....
thanks again Mark!
Thank you
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!
Just curious, where was your leak? I believe I have isolated my leak to be on the skimmer side as well. When I’m pulling from both lines there is no air but when I close the main drain and pull only from the skimmer, that’s when all the air is starts sucking into the pump. Been dealing with it for a few years and after trouble shooting many times still haven’t figured it out. Thanks
Good video
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.
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?
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.
Yes, anytime you have a suction leak or a leak on the valve and the system is off, you will lose water in your pump. If the system is air tight, your pump will hold prime even if the pump is off. Thanks for watching.
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
SO MANY videos have too short of an inlet pipe!!!
My original install pump definitely has a straight run to the pump inlet of less than 5 times the pipe diameter. I've never liked how the installer did the piping to the pool equipment in general. Things are too close such that if something cracks and needs to be replaced, such as a jandy valve or an elbow, multiple valves and elbows will have to be replaced.
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.
If your skimmer is not clogged and your pool is at the correct water level, it sounds like you might have a suction leak on the skimmer line. Thanks for watching.
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!
If you do not have a drain, then you can only isolate the skimmer. Thanks for watching.
Very informative video. I get air when I run my variable speed pump at lower speeds. Is this normal?
When you run your pump at a very low speed this can happen due to restriction of pressure as the water goes through your filter. If you clean or backwash your filter this can help. If you have minimal air at low speeds you will be fine. Thanks for watching.
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
What you are describing is purging temporarily trapped air in working (leak free) system. If a system has an active suction side leak, purging the air won't do anything as the air will enter continuously as long as the pump runs. This video is about finding an active suction side leak.
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?
If the system is running air tight, then probably not. Some chemicals can cause foaming like algaecides. Did you add an algaecide?
@@HallmarkPoolSupplies Thank you for your repy. I haven't added algecide in my pool for closely two years because it didn't need it. This year, when I opened my pool, it was only one third full, so I had to add a lot of water. The entire pool starated foaming as soon as the pump ran, even after balancing the water. The only way it stopped was after shocking it. I also did this time add a small amounf of algecide, just in case if the lack of algecide was causing it. Now I have very little foam, not accumilating, with a small drizzle at the return with pool bubbles. I can live with it, but I want to make sure there s nothing wrong with the pump or filter. There is a reason to everything, so this is why I am scratching my head with this..
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?
Yes, some valves you can take apart and lube, however some valves are sealed and can not be taken apart. Valves that are sealed you can try spraying lubricant around the stem where the handle is and let it sit. Try working the handle several times to loosen and it may help. If not, then you will have to replace the valve.
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
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?
No, this type of leak will not cause low pressure or air bubbles. This is the outgoing line, which would have leaks and would be recommended to fix. Leaks will usually get worse.

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
While the pump is running a leak around the collar or the sight glass is a leak after the pump and is a leak under pressure. Anything loose, cracked or not tight before the pump is a suction leak, causing the pump to suck air. Thanks for watching.
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.
Pressure testing with an air tank is the best way if your doing it yourself. Most techs have this kind of equipment so you can call a local pool company and they can help. If you have any questions feel free to contact me I will be glad to help.
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.
It sounds like you could have a suction leak. It would be better to discuss this over the phone one on one. Give mark a call and he’ll be glad to help you. Our hours are 10-5 pm EST Tuesday-Saturday .
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?
It’s possible you have a leak in the skimmer or it could be the valve.
@@HallmarkPoolSupplies thanks! Hoping for the valve. I had my pump off for a few hours and just turned it back on. It was air tight for about 10 minutes then the air bubbles came back. Should I keep the pump off? My pool is higher than my system.
@@samanthajameson911 Solved? If not...run your filter on recirculate instead of filter. By doing this it will burp the air out of the system. If no air coming in with recirculate...follow this video to find the air leak in filter position. Great video and explanation.
Is it possible for air to be drawn in past the seal on the motor impeller shaft?
No, from this point it’s under pressure not suction. Thanks for watching.
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?
No, air bubbles in the pump will only come from suction leaks not pressure leaks.
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
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.
There is a possibility that the impeller on your pump could be clogged. We have not made a video on that at this time. If you have any questions, feel free to contact us 10-5, Tuesday through Saturday, and we can help you one on one.
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?
There are several possibilities that could be the problem, if you would like to contact me I will be glad to help.
I don't have any valves on my skimmer nor drain, they both go directly to the pump.
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?
It sounds like a pressure leak. I made several videos on how to find a leak like a pro parts 1-4, if you want to check it out. Feel free to contact me I will be glad to help.
@@HallmarkPoolSupplies
Thanks. I have watched many of your videos. Very educational.
@@HallmarkPoolSupplies
Hi, Mark.
Using the bucket test, I am 100% sure the pool has stopped leaking. The current water level is about 4 inches below the skimmer line. The pool only loses water if the pump runs. According to your videos, I have a pressure leak. There is no sense plugging up the return lines because there is no loss of water if the pump doesn't run. I started digging near one of the skimmers where the grass is green and luscious. The ground in that particular area is extremely moist. I am in Arlington, Texas where the temperature has been 100 degrees almost everyday for the past month. The ground is hard and dry everywhere. I stopped digging after about 14 inches down because I don't know how deep the pipes are buried. Can you give me some insight on how far down the pressure lines might be?
@@Aidamari97 It depends on the site or elevation, most plumbing lines are buried 12 inches or more. If you need help feel free to contact me I will be glad to help.
@@HallmarkPoolSupplies
Thank you, Mark. I will give it another go tomorrow. I hope the pipes are not under the slab.
I have one question. I have found out that my skimmer line has leak. What should do next?
There are several things you can do to isolate or confirm that your skimmer is leaking. If you would like to contact me I will be glad to help troubleshoot this issue.
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?
You may need to check your valves, if you have any questions contact me I will be glad to help.
How about aire bubble when only run the system through the filter? when I put it to circulation the pebble disappear.
Backwash and rinse your filter thoroughly, this should help and allow the water to flow through the filter with less restriction. If the problem continues or gets worse in time, you may need to change the sand. Sand is replaced on average every 3 to 5 years. Thanks for watching.
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
There are several things that could be the problem, I have a few questions myself and I need more information. If you would like to check out my patreon page I will be glad to help.
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.
There are several things that could be the problem, I have a few questions myself. If you would like to contact me I will be glad to help troubleshoot this issue in detail.
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?
I would recommend to cut out the bad joints and replace with new fittings, this would be the proper way to fix. Caulking is a temporary fix and in time will become a problem. Thanks for watching.
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?
When the pump is running air leaks are under suction. Using soap and water may work, however it depends on the severity of the leak. In most cases it is hard to detect. Thanks for watching.
@@HallmarkPoolSupplies thank you. I was thinking if we can see the soap and water get sucked into the openings. Thank you for your video !
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.
You don’t need to repeatedly turn it on/off at short intervals. Just wait until it’s fully primed and not surging before you turn off and look again. It’s takes a little time but worth it when you find the drip (air leak)
“It will be too late”
not for me 😎 🏃♂️
Loosing my mind trying to find my air leak
Feel free to contact me I will be glad to help.
Me too
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
Could that be the line from skimmer to pump. Ihave return lines plugged off
It is possible that you have a break in the skimmer line. There are many unanswered questions, however you can turn off the pool, plug the skimmer and mark the water level. After 24 hours if you did not lose water your skimmer line may be in question. Leaving the pool off, if you remark the water level and remove the plug from the skimmer and you notice water loss in 24 hours then you definitely need to check the skimmer line. Thanks for watching.
@@HallmarkPoolSupplies thanks. And love your videos.
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.

Also can plummer grease can be used as lubricant on pool parts like the rings?
Thanks.
