I have a Hayward DE filter and due to my neglecting timely service needed to open it to break loose the DE clog.
In the process I dropped a very nice Snap-On combination wrench into the filter and it slid all the way down to the bottom. Out of reach. I tried to disconnect the vane assembly from the standpipe, but it did not want to part company. Rather than damage it with excessive force I put the filter back together with my wrench in the bottom of the housing.
So how much force does it take? I was pulling pretty hard. And assuming I don't damage it, is there an o-ring I need to replace to make the seal? The diagram is not very detailed - it appears there is a seal of some sort and I am assuming it's an o-ring.
Any advice would be appreciated!
