PB's -Question on Multiport Valve issue..
Have a Praher SM20-2 Multiport Valve (Pentair?) on our Jandy DE filter. After first backwash of the season was completed and valve reset to "filter", I started up the spa and noticed quite a bit of water coming out of the backwash line. Shut down the pump and rotated the valve to backwash and then back and tried again, same result. After moving the valve around a bit, I did finally manage to get the backwash water to stop.
Is this a result of a bad gasket? Something that can be replaced easily? Or is it just because it was the first time since closing that the valve had been moved and it just needed to soften up a bit again.
Any suggestions would be appreciated. New multiport is around $200, not bad, but would rather replace a gasket if I could...
