How To Repair Multiport Valve Diverter
Tutorial on how to replace the rusted spring and rebuild a PENTAIR multiport valve diverter on a pool filter multiport valve. These springs only last a few years max, and then most people buy a whole new multiport valve diverter top assembly, which costs at least $150, and I've heard pool stores charge as much as $450 for. These springs can be purchased for less than $5, and easily replaced with basic hand tools.
▼ WHERE TO BUY MULTIPORT SPRING
The multiport valve spring rusts out pretty quick and will prevent your multisport valve from sealing. Replacing the spring is a lot cheaper ($10-$40) vs replacing the whole multiport valve head ($150+). For this Pentair 2" multiport valve, the spring is 1-5/8in in diameter by 1-3/8in tall.

MULTIPORT VALVE DETAILS
The label on the top of the multiport valve says valve body part number is 261152. I believe that is incorrectly labeled, because that valve is only for DE filters (not the Triton II sans filter). The correct valve body part # for use with the Triton II sand filters is 261055. The difference is the flow direction of the valve. The top cover, handle, and diverter are the same for both variations of the valve body.
