Hey there - this may be a long shot but we need to replace the multiport valve on our sand filter as it is leaking through backwash line when on filter. The sand filter is old and all identifying information has long wore off. I cannot find a multiport valve that looks anything like ours, everything Ive seen attaches with screws. Ours does not. Has anyone seen this before? Any idea where to find a multiport valve replacement like this one?
