Initially, I noticed water on the concrete slab which holds my Hayward SP 2807X10 pool pump and filter cartridge. I replaced all the PVC connections to ensure no leaks. Now I can see that the water is coming from under the pump. I am stuck here. What do you think the issue could be?

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

In general the process is the same for any brand...Disassemble the motor from the pump, lock the motor shaft at the end opposite the pump, spin off the impeller (which may be covered by what is called a diffuser), replace both halves of the seal (one is pressed into the pump housing and the other rides against or on the back of the impeller) and assemble in reverse order.
