Pentair OEM Check Valve Rebuild Replacement Flapper Spring Kit 263042Z
Aug 23, 2016
Easy to replace
This is the second time in 12 years I've rebuilt this valve: it's great to be able to just install the replacement flapper assembly (versus having to replace the entire valve like with so many other check valves). No cutting, no glues; just 8 screws--takes about 5 minutes.
