Hey all, over the weekend I started having a leak in the backwash valve and I'm lost as to what the cause may be. It initially started after I did a routine backwash and recharge of my DE filter. After starting the pump back again the backwash pipe had a substantial amount of water coming from it (steady stream). I turned off the pump, opened the multiport to see what was going on. The gasket looked fine, no warping or wearing visible. The O ring has an area where its not 100% sealed (picture with red arrows). The handle feels and operates just fine too. The interesting part is that after I put the multiport back on, the leakage was reduced from the steady stream to about 3 drops per second, a huge improvement but still not what it was before I did the backwash.
Other things I noticed, with the pump off every time I rotate the handle there is some water spitting out of the backwash. I'm not sure if this is normal since I usually have a hose connected to the backwash running down hill, so I normally never see if anything is coming out of it when using the multiport. Also, I found the same thing when unscrewing the multiport, there was some water coming out for a couple of seconds then stopped after multiport was removed.
Any help is greatly appreciated!
