Searched the forums & did not see this issue addressed.
Replaced the spider gasket in my multi-port valve 9 months ago. Now when backwashing, the water empties out of the waste line. The valve assembly itself (spring, plate, etc) is in good shape, but the spider gasket seems a bit raggedy.
Before I replaced the the spider gasket the 1st time I researched the internet & I seem to remember several recommendations to install a shut off valve on the waste line because spider gasket, reportedly, can be problematic and often leaks.
And, from an engineering perspective (yes I am one of those, an engineer) the whole multi-port design seems pretty dodgey at best anyway. So I was wondering instead of replacing the spider gasket (there is no leaking when with the valve in the filter mode) are there any ramifications to installing instead a shutoff valve on the waste line then turning it off when backwashing? Would this adversely affect the backwash function or other filtering functions?
Thank you.
