Multiport/tank seal/o ring needs replacing. Can’t even budge the valve. Tried strap wrench and dead blow hammer after soaking with WD40. Suggestions appreciated.
Hi Steve, we are sorry to hear about that. You have the Pentair Tagelus Fiberglass Sand Filter, correct? There are 2 versions of valves depending upon the age of the filter - screw-on or clamp-on. Does yours have the clamp?
Screw on, no clamp. It came with a 1989 Kayak pool.
Got it - thank you!
It should unscrew in the normal direction, and you said you tried a strap wrench which would be my first plan of attack as well. Try to wiggle it back and forth or around in a counter-clockwise circular pattern a few times. That might loosen or break up the sand that is stuck in the threads.
I got it to turn 360° by threading a fitting into the return port and beating on the fitting with a 1 lb dead blow hammer. It’s getting ever so slightly easier to move but it’s still a b—h.
That’s great to hear! Add some lubricant (gobs of it) to the threads when you reinstall it to (hopefully) prevent sand from getting up in the threads.
I finally got it off. Lots of dirt/sand in the threads. Definitely gonna lube everything before I reassemble it
Thanks for your help.
