The pump Impeller or Diffuser may be melted, cracked or worn causing your pump not to prime. It is one of the last things to check for as there are several other issues that can cause your pump not to have good suction.
I have videos on most of these issues so check the list of videos below but other causes may be a suction leak, a clogged impeller, the pump lid o-ring, the Jandy valve in front of the pump may have a worn o-ring, the water level may be low in your pool, something may be stuck in the skimmer weir gate, a clogged line in your pool, an air leak in your filter air relief valve and an air leak in your multiport backwash valve. I know that is a lot to check for but any one of these can stop your pool from priming, besides the Diffuser and Impeller.
And two more obvious cause that you don't want to overlook: a very dirty pool filter and a clogged pump basket.

Seeing your boy helping you just made me calm down and relax a bit. Thanks!
This is just one of those things that happen so infrequently you forget what you did the last time you had to fix it.
Just go down the list and keep checking things off until I can pinpoint the problem. Eventually I'll figure it out.
Besides I have a pool guy anyway but just wanted to see if I could still serve some kind of use around here besides taking out the trash.
Good grief. Thanks for making this quick. Even though it's not my pump it taught me enough to get it done without a bunch of small talk. Tired of looking through 30 minute videos for 10 minute fixes
Been watching your videos and we took a look at the pool impeller and saw a huge crack in it. We bought a new one and the suction was a little better but not to great. Gonna have some one come over and check out the pipes. We love you videos! They have helped us sooo much!!! Thank you!!!
Nice video. Although around the 7:00 mark, when working on the whisper flo pump it looks like the shaft screw wasn't removed before the impeller was taken off. PH refers to "phase", as in single phase or 3 phase. Most pool pumps are single phase. A 3-phase motor allows you to wire it so that the impeller will spin clockwise or counterclockwise depending on your wiring.. you should take note of the service factor of a motor as well as the horsepower. For example a one and a half horsepower motor with an upgraded service Factor would require a 2 horsepower impeller.
Thanks for all your great videos! Very informative and real. I own an old whisperflo pump that was putting air bubbles into the lines. Sometimes it would also run with very low pressure or none at all. Resetting the pump would fix it. I replaced the seals in the pump including the ones on the impeller and the difuser. The seal in the impeller was rotted. After that there are less are bubbles but still the occasional low pressure issue. I guess the impeller is next for replacement!
Sounds like something is leaking. Did you try my plastic bag trick yet? Tie a regular plastic bag at the pump discharge (where the threaded pipe and top of pump meets the pipe & one in the intake in front of the pump - also at the point where the pipe and pump meet). Try priming it again as see what happens. Usually the pipes will melt if it ran dry for a long time. Sometimes the diffuser inside will have melted also.
Very helpful. My problem was my impeller was loose after replacing the motor a few months prior. It wouldn''t prime.
Thanks! My pump overheated ( the oring popped out on one side of debris basket lid ) . I found the wear ring was 2mm on one side, 2.6 all around elsewhere. Put a new one in and new diffuser seal and it didn't help at all. I then noticed the impeller was worn where the wear ring goes around it. So now Im going to remove the impeller and put a new one on, and needed to know how to do that. Thanks again.
I show removing the impeller in this video: Motor, How to replace your pool motor: ruclips.net/video/J7BVkIp4l_Q/видео.html
Good camera work bro
Thank you for the good advice. I'm going to try the plastic bag trick tomorrow. I'm terrified that a pump part may have melted because the pump is old and some parts aren't available, and buying a new pump isn't really in the cards at the moment. You wouldn't happen to know a good pool man in the Los Angeles area by any chance?.
Nic video man! But at about 8:15 when you are talking about the motor's HP, you note that sometimes it is backwards and listed as PH. PH on the motor refers to the Phase of the moor. It is either single phase or 3 phase (PH 1 or PH 3)
Bho bjb
And you put on a higher horse power impeller than the one you took out. You can tell by the space between the blades on the impeller is greater. This will cause the motor to burn out.
Love your videos I signed up to the pool group online for 10 bucks. That’s how much I support you and how much you
Have helped me
Thank you. Looking forward to connecting with you in the group! 👍
Man you are the bomb and honest!!!!! can you please come work on my pool (smile)
As always, an informative video. I'm currently working on replacing the motor for my DuraGlas PUMP .Unfortunately ,
However , the impeller is stuck. I was reluctant to use pliers or channel locks on it - as I'm afraid it'll break - BUT it looks like that's what you did. Is the DuraGlas impeller pretty tough, and Can I use channel locks on it? I tried to use a strap wrench on it, BUT it didn't work.👎
You can take it into your local pool store and they can mount it and use an impeller wrench on it.

Thanks. I'll give that a shot.
Call Hayward and ask for a Warranty service. The bearings are wearing out for some reason and the motor will burn out very soon. There is a one year warranty on the pump and motors. The day the warranty guy comes out, leave your pool off so he can start it up and see what you are describing. Once the motor warms up the bearings quit down so it is important that he is the one to start it up. Oh, don't mention the fact that you took it apart as it may void the warranty.
Excellent video! Thanks for sharing.
The only question I have is what is that vent thing on the wall where the pool is enclosed in the building outside it looks like a very big vent whats that called and why is that there? To provide the air or something? And I have also seen one in a parking garage too in the building not even near a pool so I wonder why they have it there too?
Thank you . you are the best.
Excellent video, thank you!
I'm having trouble turning the damn thing to open it. It's a trouble we have every year. We have to close it during the winter so we don't have a choice. Any tips?
I have a Hayward pump and the impeller is clogged. It has 6 bolts. I started to remove the bolts. But two bolts just spun and I couldn't remove them. Any ideas?
Should air from the Pentair motor be exiting near the front of the motor (pump side)? I would expect it to exit the rear of the where the motor screen is. Air is existing and blowing from the middle towards the lid. I do not have any water leaks. Thank you
If it is a really old motor it could be the bearings and the coils burning out. Overheating.
I've also found that I can't get a prime after the pump ran dry one day. I put a hose in the basket and ran the pump, and still nothing. But if I poured a big bucket of water in, it squirted out the bleeder valve and pressure rose -- but as soon as the bucket was empty, it dropped back to zero. Does that mean my pump works but something is leaking? Or the pump isn't pulling hard enough? Btw. do you have a pool business anywhere? (I'm in Los Angeles, in the Valley.)
Do you ever answer questions? I have a Hayward 1 hp inground pump and it starts out working for 20-30 seconds, then suddenly it stops sucking. Is this an impeller problem?
Maybe an air leak. Air is getting into the pump from somewhere.
Very informative, thank you..
Awesome reference! I have a Hayward Ecostar SP3400VSPVR that is giving me a drive error”drive failed to start”! I have a new control board so I don’t think it’s that! I tested the motor for continuity and it checked out okay. The manual says check impeller, diffuser, shaft seal, and motor. Would you say I am heading into the right direction?
Could be a bad drive. They had many issues with those. Hayward has extended the warranty to 4 years so if yours is from 2015 and on it is probably under warranty. You would have to call them with the pump serial number.
Swimming Pool Tips, Reviews & How To - SPL thank you for everything!
another great video, thank you
Excellent, you should get paid for this:)
My hayward superpump would not prime . this is on the money because diffuser spring seal was corroded and the spring was broken
You would be surprised how many pumps that were produced in the last few years have failed in the first year. They are now making pool pumps in China and the quality has suffered... cheaper is not always better.
This fact seems to escape most people. Very shortsighted.
Just got a diffuser for jandy flopro and its so tight around impeller had to force it on. This cant be normal. Impeller needs to spin freely.
Sounds like the motor shaft is no good.
@@SPL the impeller does spin, motor works fine, i just had to replace broken diffuser and new one dont fit over pump impeller had to really force it on to line up the pins and 2 screws
And now its so tight from diffuser pinned , impeller cant move. Thanks for ur help
Recently cleaned filter (Haywerd DE), and now the pressure fluctuates from about 10 PSI to almost zero, with corresponding fluctuating flow. Any advice would be greatly appreciated.
Sounds like air in the suction line after opening the filter up. do you have an attached spa?
Hey, thanks for the reply bud! No spa, but it looks like I fixed it. Suction was apparently so strong at the skimmer that it would draw all the water and suck up lots of air before more water replaced it. Added more water and it's good now. Interestingly though, there aren't any videos up yet that address this problem. Hope this helps anyone else with the same problem.
My pool pump is less than a year old. and it failed pumping. It's a shame that things are failing after a short time of working.
good job.
10 year old pool, came with the house. Pool/spa worked well. No water in the pump. unit shakes and gets smoking hot. But I think the motor runs.
Sounds like air in the line somewhere.
Swimming Pool Tips, Reviews & How To -MrDgvb1 thank you very much, i tried priming it no luck, now i just get a humming sound
Is there another suction source like a spa or main drain? Or you can dry a drain bladder in the skimmer and see if it primes that way.
Pool is pretty full, now motor makes an extremely loud really loud hum and wont spin even a little bit, i can still spin impeller with my fingers though

Can a pin. Hole in the diffuser cause my gpm to be 10 gpm lower than normal
Usually not. But it may be warped or have other issues.
Actually took a 30 second video. . What is weird is that the pump rumbled and grumbled and didn't pull water. Now just that loud as hell hum.
I have a cracked pentair pump housing from the recent freeze. Would you recommend replacing the entire pump or would it be fine to jusr replace the housing? Thanks!
If you can find the housing and the pump is 8-10 years old I would do that. Heard parts are in short supply. Upgrading to a new VS pump would not be a bad idea either. In 1-2 years the energy savings will pay for itself.
Your shaft seal is installed opposite mine, weird.
FYI- That is a pair of channel locks and not a wrench. It is advisable to use channel locks on a plastic impeller, recipe for disaster.
Yes, yes Channel Locks. I call it a wrench in a few of my videos ;)
that reads like you left out a word; should it read "It is advisable to NOT use channel locks on a plastic impeller" ???
can you over tighten the impeller causing the pump to run very hot
Not that I know of. It is possible to install the wrong impeller and it is too tight in the Diffuser.
Swimming Pool Tips, Reviews & How To -MrDgvb1 would there be a difference between an impeller for a 1hp 's a 1.25 hp?
I think the difference is greater between a 1 hp and a 2 hp impeller. You can for instance use a 1.5 hp impeller on a 2 hp pump but not a 2 hp impeller on a 1 hp pump. You should match up the impeller for your exact pump hp for best results.
Last question: ok, ruling out the impeller, I replaced the diffuser, then what could possibly causing the pump to run hot. Water is flowing nicely in the pool. Thanks
Could be burning out. The bearings inside are wearing out causing excess heat.
Also Check Small PLASTIC Threaded PLUG at Bottom Of Basket Strainer, It Can Be Broken/Damaged and Not Readily Observeable Since It Is On The Suction Side...

Great Video! Should start with...Please don’t try to do it yourself and then expect to pay less for a pro to fix your repairs
Question my motor turns on for a few minutes then it turns off & the circuit breaker shuts off? Whats wrong with my motor
+Raul Villegas Depends on a few factors. What type of pump/motor is it and how old is it? And does it actually prime up and run or just buzz?
Hayward 1 1/2 hp, I bought the house two years ago , it primes then it turns off
+Raul Villegas Common problem with Hayward pumps is the difusser warping and the impeller gets trapped and stops spinning. That would be my best guess with your pump type. You will have to pull it apart and inspect the parts.
This video covers taking it apart in a round about way. You will see all the parts I mentioned.

Wow thats a crazy good video, of a how to, but it's not that easy to properly fix a pump. I do give you credit for packing in a bunch of common pumps, like the whisper junk and the dreaded NORTHSTAR. removing a impeller from a northstar, usually requires totally disassembling the motor and placing the rotor in a vice, and carefully removing the impeller, with a BIGAZZ 480 channel lock.
Good video - you would think the pump manufacturers would make it easier to have access to the impeller shaft. There's always something in the way.
We’re can I buy impeller
Take your pumps specific info into your local pool store and they should stock a number of different impellers.
I am changing the diffuser and the impeller on my sta-rite dyna-glas pump.
I noticed that the diffuser and the impeller fit a "too" snuggly. I can't imagine this is good. But this is the first time I am doing this.
Both diffuser and the impellar are brand new.
Here is a link of the video. Notice the grinding noise when the diffuser is "loosely attached" to the pump.
ruclips.net/video/qYuAgrkMxSw/видео.html
Looking for any advice on what is going on here.
The only way to tell if there is an issue is to wire it up and turn it on. Due this while it is outside of the pump itself and see how the impeller spins. It may be okay or the diffuser may be the wrong model for your pump. If the impeller spins good then you should be okay.
Thanks. I followed your advice and it worked. The reason it was scrapping against the diffuser was because I had not completely screwed it in.

I really hate whisperflos
you speak too softly in all of your videos; especially with all of the background noise.
Speak softly and carry a big pole - or was that a stick? ;). Noted. Thanks.
please send me Costner carr
The impeller should spin but not spin like a top. Is that right?
Yes, it should be fairly stiff.

I really love wisperflows !
