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.

Welcome to TFP!!!Sorry you have not gotten any responses, and I am no help. Bumping it up.
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.
Ok. So this is how I removed the valve piston. Embedded in ABS where the SS pin is place is a 5/16 hex head. Used 5/16 socket/ratchet turned CC ones the assembly started to turn I pulled up slightly while turning rachect. Assembly came out no issuea. I lubed orings and reinstalled for now. I believe there is possible issue with orings used. There are different oring material other than what is used on this application. I think it’s EPMD. I might have the acronym wrong. Maybe Kalrez or Teflon incapsulated they are both used in chemical and acid solution environments. I will be installing a Multiport valve instead of replacing the piston assembly. Hopefully that will work better than the Push/Pull Valve. Picture hard to make out but you can see the hex head top of shaft
