Question about Hayward 1HP Super Pump II Inground Pool Pump
I have a Hayward Super Pump II that is leaking. It is leaking between the seal plate and the pump/strainer housing.I have replaced the housing gasket but it still leaks. Any ideas?
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.

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.
