Product details

The Pentair 274417Z is the waste valve seal for the FullFloXF backwash valve. It is the genuine Pentair part.

What the waste seal does

A backwash valve has to hold the waste port shut every minute it is not backwashing. That job belongs to this seal. When it hardens, takes a set or nicks, the port stops closing completely and a steady trickle leaves the waste line while the system is supposed to be filtering. On a pool that is topped up automatically, that leak can run for weeks before anyone notices the water bill.

Before you order

This listing is the seal on its own. The waste seal spring is a separate Pentair part, and so are the inlet and outlet diverters. If the valve is already open and it has some age on it, look at all of them while you are in there rather than doing the job twice.

Questions and answers

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

What symptom does this part fix?
Water running or trickling out of the waste line while the valve is set to filter. That is the waste seal no longer closing off the port.
Does the spring come with it?
No. This is the seal. The FullFloXF waste seal spring is a separate Pentair part.
Is it the genuine Pentair part?
Yes, Pentair 274417Z, the factory waste valve seal for the FullFloXF.
Should I replace the diverters at the same time?
If the valve is apart and it has years on it, it is worth looking at the inlet and outlet diverters as well, since both are separate Pentair parts and both wear.
