Product details

The Pentair E-12-S2 is the spider gasket for 2 in multiport valves. It is the rubber seal that sits inside the valve body and divides the ports.

What it does

A multiport valve works by rotating a key against this gasket. The arms of the gasket seal off the ports you are not using, which is how one handle can mean filter, backwash, rinse, waste, recirculate or closed. There is nothing else in the valve doing that job.

How you know it is worn

The symptom almost everyone meets first is water running out of the waste line while the handle is set to filter, or the pool level dropping for no visible reason. That is the gasket failing to seal one port from the next. Rubber under constant compression takes a set with time, so this is a wear part rather than a fault.

Before you order

Spider gaskets are specific to the valve body. This one is carried with the 6-position top mount valve parts for 1-1/2 in and 2 in multiport models 501131, 501130 and 501231, and is also listed with 2 in BWVL-MPV DE and sand side valve parts. Confirm your valve and port size before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

What is a spider gasket?
It is the star shaped rubber seal inside a multiport valve. Its arms separate the valve ports so that each handle position sends water where it is supposed to go.
Why is water running to waste on filter?
That is the classic worn spider gasket symptom. When the rubber flattens or tears, water bleeds past the arm that should be sealing the waste port.
What size valve is this for?
It is the 2 in spider gasket.
Which valves is it listed for?
It is carried with the 6-position top mount valve parts for the 1-1/2 in and 2 in multiport models 501131, 501130 and 501231, and is also listed with 2 in BWVL-MPV DE and sand side valve parts. Match your valve body before ordering.
