Pool leaks from the backwash port.  Have replaced the spider gasket three times and the valve compression spring, gaskets and washers.  Still leaking.  Looking for suggestions.  Thanks in advance.

At this point, I would recommend replacing the complete valve. The valve body could be the issue. What is the make and model of the valve?

The SM20-3 is a style of multiport valve that is used on several filters. The plumbing arrangement will depend on the filter. What is the make and model of your filter?
