Waterway did change the wet ends slightly (the difference is only minute and you wouldn't realise without meausring) and if yours is the older version you may need to change the entire wet end.

I'd advise you to take the pump to someone who can advise you and perhaps consider changing the entire wet end so that you have a new mechanical seal too.

If you're in the UK I can possibly help but I suspect that you're in the US...

the problem with the sound is the bearings inside the motor are going out. i have the same pump and i have to replace the motor. replacing the bearings is very hard and will cost you about the same after you carry the motor and new bearings to a shop to be pressed in. hope this helps!!

Need to change the seal on a PF-50-2N22C


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. If you need more specific directions, please add a comment with your question(s) or contact me using our web site at www.arrowpools.net.

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

There is a seal in there that a local pump repair shop can fix for about $30 - $50 with parts and labor. Waterway pumps use a 1000 seal that is not a seal the homeowner is usually successful at replacing themselves.
