After backwashing when putting valve back to filter and disconnecting backwash hose to the street and turning pump back on water still pours out of backwash valve..help!
I had to order a rebuild kit for my sand filter that included a spider gasket and a few other things. My handle was also not hard to operate when I had this issue. I would splurge and get the rebuld kit/gasket and read over the article I posted above.
Too bad it wasn't under happier circumstances. Do you have a push-pull valve, a multiport valve, or is the valve just a lever in the filter base?
Push-pulls have O-rings in them that can split and tear. Not a huge problem to replace if there isn;t a lot of corrosion in the pipe to resist pulling the stem out.
Multiports have a spider gasket that can fail. That's a fairly easy fix and you can find how-to videos on youtube, even.
The kind with the valve in the base (like mine) I'm sure has some kinds of O-rings inside, but I shudder to think how much work replacing them might be. That said, sometimes mine dribbles a little. I've learned to learned to leave the hose attached and run the filter a minutes to fill it, then shut it off and open and close the valve a few times and let gravity flush any stray bits of grit out, then make sure the handle is pushed all the way to the stop when closing it.
