no, based on the Watkins model # you gave it should be an Aquaflo FMHP pump.the correct part # should be 92290015 & o-ring 5120-06, if you can verify you have a Starite DJ series pump then the part # you have is correct.

Leaking at plug. Poor circulation

Written on 6/12/2019 by Guest

I was having trouble with good circulation when cleaning the pool. When I switched from backwash there was hardly any pressure. I had noticed some water on the floor of the pump house in the past but I never knew where it was coming from. This time I saw it dripping from the plug and I noticed it was loose.

It came out when I tried to tighten it. I thought it was the o-ring and purchased one at a local hardware store, but then I realized the threads on the plug were stripped. I made a temporary repair with plumbers tape to keep the plug in.

This is an old Sta-Rite pump and I found this part on the website when I googled for it.

$11.00 and a few days fixed my problem.

Were these instructions helpful?
