Product details

The Waterway 711-6400 is the skimmer gasket for the float valve. It is the genuine Waterway part and appears in the Renegade gunite skimmer parts diagram.

What the float valve is for

Pool water level drops with evaporation, splash out and backwashing. If it falls below the skimmer mouth, the skimmer starts pulling air instead of water and the pump loses prime. The float valve is the mechanical answer to that: it drops with the water and closes the skimmer port before air can get through. The gasket is what makes that closure an actual seal rather than a plastic part resting on another plastic part.

When to change it

Gaskets seal by compressing. Once the material has hardened, taken a permanent set or gone brittle from chlorine and sun, it stops compressing and the valve leaks past even though nothing is visibly broken. If the skimmer is open for any reason and the float valve is out, this is a small part worth renewing while you are there.

Questions and answers

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

Which skimmer is this for?
It appears in the Renegade gunite skimmer parts diagram. Check your skimmer against that diagram before ordering, since skimmer bodies and float valve designs vary between families.
What does the float valve do?
It is the safety that stops the skimmer drawing air when the water level falls below the skimmer mouth, which protects the pump from running dry.
Is this a genuine Waterway part?
Yes. It is Waterway part 711-6400.
Do I need to replace it if it looks intact?
If the gasket is hard, compressed flat or has taken a permanent set, replace it. It can look fine and still fail to seal, because a gasket seals by squashing and a hardened one no longer can.
