If you have a Hayward Super Pump powering your above ground or in ground pool then you will know from time to time you may develop some air leaks inside of the pump. This air that gets sucked in from the pump fittings will travel through the swimming pool plumbing and then wind up blowing bubbles from the return jets of your pool. A common mistake is that some people think the return line is leaking because they see the air coming from the returns lines but in fact the air is being drawn into the pump from the suction side.There are a few places on the Hayward Super Pump that you will want to make sure are sealed well.

How To Check The Pump Suction Fitting For Leaks

On the front of the super pump inside of the suction opening you will find a PVC fitting that is screwed into place. Hayward Super Pump Front ViewThis fitting commonly leaks because the thread sealant or Teflon tape has worn off because the filter system has been disassembled and reassembled a few times. Another reason the suction fitting could be leaking is because the pump ran dry (with out water) and that created some steam inside of the pump and then expanded the suction threads a bit. To correct an over heated pump fitting that is loose on the suction side, you will want to wrap the suction fitting with Teflon tape and then some thread sealant. So if you find that the suction fitting is loose in the from of your super pump, now you now what to do.

How To Check & Tighten The Super Pump Drain Plugs

The next thing you will want to make sure is not leaking on your Hayward Super Pump is the drain plugs on the wet end of the pump. the wet end of the pump is also what they call the pump housing.On this housing you will find two drain plugs. One is on the from of the pump housing and one is on the side. Depending on the age of your super pump will determine if you have tapered drain plugs that will require Teflon tape and thread sealant or if you have the newer style drain plugs which will have washers to seal the drain plugs.

So now that you know that there are two different types of drain plugs you will need to know how to repair them so they stop allowing air to be sucked into the pump which will create air bubbles in the pool jets. So if you have the tapered drain plugs you will want to remove them from the pump and then wrap them with some Teflon tape. You will then want to thread them back into the wet head / pump housing.
Hayward Super Pump Side
If you have the newer style of Hayward Pump Housing drain plugs you will need to remove them as well and then inspect the rubber washer that is on the drain plug. In some extreme cases you will see that the rubber washer is all dried out from age. Sometimes you will remove the drain plug and find that the rubber washer is completely missing. Either way, if your rubber washer is damaged or missing you will need to replace it so the super pump will no longer suck air through the drain plug.

You can find replacement pump housing drain plugs for the Hayward Super pump online where swimming pool pump parts are sold or you can buy them from a local swimming pool supply store in your hometown area.

Tools You Will Need To Check The Super Pump For Air leaks

If your Hayward Super pump is still connect to the filter system you will need to remove it by loosing the unions that should be on the suction side and the discharge side of the pump. You can loosen these unions with a large pair of channel lock pliers. Once you have the pump removed you will need a 9/16″ open end wrench or socket to remove and replace the drain plugs. You then will need some Teflon Tape and thread sealant to seal the pump housing drain plugs.

  1. Hello, I own a Hayward Super Pump similar to the picture above and installed about 2-3 yrs ago. I am having suction problems. While water is being drawn into the pump housing, I can also see water shooting out from the opposite side (suction) which I believe is not good. I’ve cleaned the impeller, lubed the gaskets and replaced old ones. I am concerned with this lack of suction. Any suggestions would help.

  2. I am having a similar problem, but only when I try to vacuum through the skimmer. I replaced the cover gasket, and the pump runs fine normally until I hook up the hose to vacuum. Is it still likely that something inside the pump is the issue, or could it be more likely something in the skimmer?

    Any help would be appreciated.

    Thanks,
    Greg

  3. Air was in my water system and water leaking at the super pump connection. But, water was pumping through the system fine. I replaced the cover gasket and the rubber seal on the pump at the connection.

    Now water is not pumping through the system. I put the pump back in place and tightened the four screws just as I had done taking it off.

    What could I have done to stop water from pumping through the system? I would appreciate any help you can give me.

    Thank you, Brenda Adair

  4. Air can enter the pump suction when vacuuming pool if any of the following exist:

    Crack in the flange plate which rests on top of the skimmer basket and connects to the vacuum hose.
    Flange plate does not completely cover the skimmer basket opening,
    Vacuum hose swivel end connected to flange plate rather than the vacuum head which attaches to the end of the pole. The swivel end of the hose is designed to rotate (and hence will not be leak tight)to allow easier maneuverability around the pool during vacuuming. If the swivel end of the hose is connected to the flange plate in the skimmer and is out of the water, air will leak across the swivel joint allowing air to enter the pump and cause difficulty maintaining vacuum.

  5. I have a hayward super pump. After I prime it, it sometimes takes a minute to actually start really pulling the water in. Once it fills, it runs ok for a while and then the water level in the housing will drop. I also lose suction quickly when I hook up vacuum hose.I have checked every gasket and connection. Could I have a leak or crack in the actual lines that run underground from the skimmers to the pump? Any help would be most appreciated.

  6. i installed a new wayward pump and i started having bubbles
    i checked everything
    when i start it runs for five minutes no bubbles
    after five minutes bubbles appear
    what do i do now

  8. I just had a brand new Hayward system (filter and pump) hooked up to my pool and it is doing the same thing my old one was. The only thing that is the same is the cord running it and the intake on the side of the pull with the screen basket and the square pipe on the outside of the pool running from that. Everything else has been replace and it is still losing vacume and pressure on the return in 5 mins or and hour sometimes. Help

  9. Water leaking out around drain plug on Hayward Super II pump. I bought new plug with new gasket but the female threads in the pump housing don’t grip the plug enough to pull it in tightly enough for the gasket to seal. Tried lots of teflon tape and that does not do it. Any solutions? Thanks
