Sand filter at 40psi. No return and skimmers seem to be leaking? HELP!!

Have you tried backwashing your filter? It could simply be completely stopped up.

If you've got a multi-port valve with a rotating handle, there's not really a way I know of for them to fail by obstructing flow. Leaking, yes. But blocking the flow, when in "Filter" position? Not so much.

I tried backwashing for about 2 minutes and it seems to have helped a little. The gauge never creaped above 30psi yesterday. Is there a proper way to backwash? A time? I was looking for a new valve and it says clear buble to know when the backwash cycle is over. Is there something to be looking for? Also I went to the pool store and bought some polyquat thanks for the tip it cleared my water up in about 10 hours green to blue is nice :). To make matters worse for me my motor is now making a screeching noise that I am guessing is bearing so a motor replacement is in my future. Thanks again for the help so far.

You should inspect your sand.

Also, to troubleshoot your installation, you'll need to take and send pictures. Send them to either poolforum.pic AT gmail DOT com or just poolforum AT gmail DOT com
