My hubby replaced the sand in our pool. He can't get water to stop leaking around the clamp area of the MPV. It is a pentair valve 261886. I called the co. For help but they couldn't find the valve on their website even though I was able to bring it up. Anyway, hubby doesn't remember where the Oring was located on the valve as it connects to the filter. Can anyone help before he blows up my pool?

The oring goes below the flange on the mpv then it mates with the top of the filter, and band clamp encases to top of the filter, the o-ring and the flange on the mpv.
 
You have a Sta-Rite (owned by Pentair) Waterford sand filter.

If you asked for a valve with that number they can't find it. Your valve number is 261186. The O ring fits onto the bottom of the valve and may need to be replaced. It should be a U9-369 (Sta-Rite number) or generic.
