PVC fitting on filter

As stated on another thread, I had to do an emergency shut down when I found a leak on the pvc fitting from the backwash side of the filter. Now that the temp is in 70's I'm ready to reconnect and start the pump again. I unscrewed the connection and there is nothing behind it so I'm assuming the teflon tape was just old and I just need to add new tape and reconnect. Anthing else I need to think about, or am I missing something? Sometimes when things seem so simple...well you know!

Update: I rewrapped teflon tape on connection, got everything hooked back up and started filling the pool back up. As the water got back to skimmer level I sat and watched for leaks...now I know the real problem....the water is actually draining out the back flush hose not the connection! What does that mean??? I stopped filling the pool. Please help!!!

Probably have a problem with the multi-port valve on the filter. Quite common. There is a gasket in it that looks somewhat like a spoked wagon wheel and some call it a spider gasket. It is prone to popping out of the channels molded in the valve body and when this happens you get leaks between the ports. I am assuming that is the kind of valve you have. If so, put the handle in between positions to release spring tension and remove the 6 screws. Comes apart easily and the problem should be obvious by visual inspection. Before you pull the two halves apart just mark them so you orient them correctly during assembly. Nothing will fly apart. If we're on the right track post back and we'll walk you through replacing the gasket.

Al,
Thanks for the reply. Yes it was the spider gasket, unfortunately I had to buy the whole diverter valve assembly. It was $40, so not too bad. Everything put back together and working fine! Added 2 gal of bleach, ran pump all day, pool is ready to open...well as soon as we have a few more 80 degree days!
Thanks again, Robert

Glad it was a simple fix, and relatively cheap also.
