Product details

The Waterway 505-3010 is the multi-port valve split nut assembly for Carefree, ClearWater and TWM sand filters. It is the clamp that holds the valve onto the top of the tank.

What it does

The multi-port valve does not thread into the tank. It sits on top and is held there by a split nut that pulls it down evenly against the seal. Everything about how the valve behaves under pressure depends on that clamp being intact and pulling square.

Why they get replaced

Split nuts are plastic and they are the first thing someone over tightens when a valve starts to seep. Once the nut is cracked or has stripped, no amount of turning will bring the valve down evenly, and the leak comes back every time. A fresh assembly restores the clamping load the seal was designed around.

Questions and answers

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

What does the split nut do?
It clamps the multi-port valve down onto the top of the sand filter tank so the valve seals against it.
Which filters does it fit?
Waterway Carefree, ClearWater and TWM sand filters.
Is it one piece or two?
It is supplied as a complete split nut assembly, so you get the full clamp rather than a single half.
Why do these fail?
Over tightening. The nut is plastic and gets cranked down hard when someone chases a leak, and once it cracks it cannot pull the valve evenly.
