Hello all, and thanks for accepting me as a member. I have a Pentair FNS Plus 48 filter. The normal flow and backwash valve got stuck mid way. I went to the local pool supply and they showed me how to wiggle and pull the whole valve up and out. Mine must be the one they forgot to lubricate, I unscrewed the cap, wiggled and pulled it up and out about three inches, but it will not wiggle or raise anymore. I would hate to replace the entire assembly. Any tricks or tools to keep pulling the valve assembly up and out? We are at 101 Farenheit here in the OC, so I will wait until later tonight to keep working on it.
