Pentair Multi-Port Valve and Sand Filter
I recently installed a Pentair TR-60 with a multi-port valve attached. After several bad storms locally the filter needed to be backwashed to lower the pressure in the filter. Backwashing the filter for three minutes cleaned the debris from inside of the filter and allowed the pressure to return to normal. There was one problem though, the filter seemed to be making a hissing noise when the filter was running. Water was coming out into the pool at it's normal rate so I didn't really have any idea what the reason for the hissing noise was.
It turns out that it was my own error, my filter unit did not come with directions so I had nothing to refer to, but what I did wrong when I backwashed the filter was neglected to rinse the filter. That is only necessary with the multi-port valve the two position valve doesn't have a rinse setting.

After I ran through the cycle again, backwashing, and then rinse for 30 seconds then back to filter the hissing noise went away and the filter operated as it was designed to. So if you have the same system, a Pentair TR-60 with a multi-port valve the steps are backwash for three minutes, rinse for 30 seconds and then back to filter.
