    pentair pushpull backwash valve stuck

    Hello everyone I am trying to replace either the o-rings or the whole push pull assembly...however I can't get the assembly out of the pvc valve. I have removed the screws on top of the assembly and the screws attaching it to the pvc valve..I don't know how much force to apply to pull assembly out. I would appreciate any ideas on how to get this thing out...I'm assuming it is something to do with the large o-rings being old. The pushpull backwash valve is old Pentair attached to Triton sand filter. Pool built in 1987, it is an inground plaster pool.

    no problem, I had my pool person get it out with brute force, it broke, however most of the assembly was out and it was no problem getting last piece out..But it solved the problem of whether to replace o-ring or entire assembly. thanks

    Sometimes, that's how you get it out. Its amazing how stuck those pistons can get. An fyi, every 3 months, or whenever the piston starts to get stuck, remove it and lube it.
