The pump seal is leaking and needs replacing and requires removing four 3/8 bolts (9/16) wrench and removing the motor then the diffuser to get to the impeller and seal . A 7/16 wrench holds the rear motor shaft behind the springs and impeller spins off to reveal the seal which has two parts one on the impeller with a spring and one in the seal plate is white ceramic/ porcelan whatever they use. Part number is an SPX1600KA on super pumps and 1500KA wassome above grounds. When replacing do not touch the mating white and black surfaces with your fingers.

Hayward pool pump leaking from underneath motor


The leak is an indicator the shaft seal has failed. It leaks by design to let you know to replace the seal before water gets into the motor and ruins it. Replace the seal right away.

My pump is leaking .What causes that and how do I fix it


Thank youfor posting your question here on Fixya.com. The leak is likely caused by a defective pump seal. If you look at the parts breakdown at http://www.star-pool.com/assets/Hayward-Pool/Hayward-Manuals/Hayward-SP2610X15-Super-Pump-Parts-Diagram.pdf you can see the seal and the other parts that must be separated in order to replace the seal.

THE HARD WAY! Once you are sure the seal is defective you need to buy a new one along with a diffuser gasket, a pump housing gasket and some pump gasket grease.

The 4 housing cap screws and the impeller must be removed in order to remove the 4 motor cap screws. The hardest part of this process is removing the impeller. The cover on the other end of the motor should be removed and the motor shaft held with a wrench. The impeller must then be removed by turning it with a large pump pliers or by inserting a screw driver into one of the holes on the outer edge of the impeller in order to turn it counterclockwise with the shaft held with the wrench. If this damages the impeller it should be replaced.

Now remove the 4 motor cap screws and everything is apart except the seal. Half of the seal can be removed from the motor shaft and the other half from the seal plate. Placing a socket on the back side of the seal that is on the seal plate allows the seal to be removed by tapping it with a heavier tool (hammer or pump pliers). Clean this area, apply a little silicon adhesive to the area and insert the new seal half into the seal plate using the instructions that are included with the seal.

Use pump gasket grease on the pump impeller gasket and reassemble the completely reassemble the pump.
THE EASY WAY!
Remove the piping from the motor and the electrical conduit and wires from the end of the motor. Bring the pump to Leslies pool supplies (I don't work there or own any of their stock) . If they are not very busy then they will do the above and only charge you for the parts while you wait.

I have replaced so many seals I almost always do it myself at the pool site but it is not easy for the first timer.

Thank you for posting your question here on Fixya.com.


The pump would have gotten very hot running all that time dry...the best way to fix your situation would be to replace all the o-rings/gaskets and the pump seal. All told the parts are about $20 and should include:

SPX2700Z4 - STRAINER COVER O-RING
SX220Z2 - DIFFUSER O-RING
GMX600F - HOUSING O-RING
SPX2700SA - SEAL ASSEMBLY

If you are still having a leak, replace the drain plugs and the gaskets at the union connectors on the inlet and outlet. Here it gets a little tricky. Hayward sells them as parts kits: the plugs are SPX4000FG; the unions SP2700UNKIT. You can probably buy a bag of o-rings from a local power transmission supply house that will work for far less...something like $6 for each bag. Take one of each there and they can ID the best o-ring to use.

At this point you have spent upwards of $40 on all these pieces...if you still have a leak the damage was worse than expected. A warped housing, damaged cover or something else, perhaps even in the pipe(s) closest to the pump need to be checked. The best way for that is to call in a plumber or leak detection service to pressure test the lines and equipment. It will run a couple hundred dollars but will be the only reliable way to locate the issue and fix it.

I have a Hayward super pump. I just changed the housing gasket, but it is still leaking from somewhere at the bottom. I can't see where it is exactly leaking because there is no clearance between the pump...


You forgot to replace the most important part...The" shaft seal".It is behind the impeller. Be sure to remove all the pieces of the old seal off the impeller ,(they always come off in pieces) and put silicone on the rubber part that sets in the pump housing. Make sure you keep the white porcelain surface perfectly clean, and you will also need to replace the ribbon gasket again.

I replaced the motor on my super 2 pump with a new shaft seal. Put it all back together including electrical and now it's leaking from the bottom. I retightened the screws to make sure they weren't loose...


Most likely leaking from either the shaft seal, or the valute seal (big seal plate o-ring). When you replaced the motor you should have also replaced the shaft seal. If not go back and do that whether it's leaking or not. If you get your head down and look at the bottom of the pump while it's running you should be able to see the water coming from the joint between the seal plate, and the seal plate housing, or just behind that from the bottom of the motor probably from the vent holes in the motor housing. If it's coming from the motor then the shaft seal is leaking, and the water is traveling along the shaft and out the bottom of the motor. This will eventually get into the motor and seize up the bearings. If it's coming from the valute seal, then you need to either replace or re-seat the seal. As a general rule you should always replace the shaft seal, and diffuser and seal plate o-rings when you replace the motor or split the seal. I'm not as familiar with the 2 speed hayward super 2, but the standard super 2's have a small ribbon seal, often called a rubber band. They are infamous for going bad especially after pulling the pump apart.

One or more of a couple issues is at play here. First would be the seal replacement. Even if you used the correct seal if you touched the surfaces or failed to install it properly it can and will leak. Second, inspect the housing around the seal fit and the stem of the impeller for cracks. A hairline crack is enough when placed under pump operating pressure to allow a leak. Somewhere in there is your solution.
