Need to replace top valve - Sta-Rite T-180WF

I need to replace a top valve to a Sta-Rite T-180WF sand filter. Not sure of the part number. Your recommendation?

Hi LRG0351,

You will require the 261186 Top Valve which is the replacement valve the original WC112-148 valve that came with the Sta-Rite T-180WF filter. The WC112-148 valve was discontinued and replaced by the 261186. The 261186 valve will work on your T180 WF-H Sta-Rite Waterford filter, however, the ports on the valve are not in the exact same location so some re-plumbing is required.
