Product details

The Pentair 516315Z is the weir gate assembly for Bermuda gunite skimmers, in black. It is the genuine Pentair part.

Why the weir matters

The weir is the hinged door that floats in the mouth of the skimmer. It sits just at the waterline and forces the incoming water to pass over a narrow lip, which speeds the surface flow up and pulls floating leaves, pollen and oils toward the skimmer instead of letting them drift past. It also acts as a one way gate: when the pump shuts off, the weir drops closed and keeps the contents of the basket from washing back into the pool.

When it needs replacing

Weirs crack, warp and lose buoyancy. If yours is stuck flat, floating too high to seal, chipped at the hinge or simply gone, the skimmer is doing far less than it should and debris will sit on the surface.

Questions and answers

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

What does the weir gate actually do?
It is the hinged floating door in the skimmer throat. It raises the water speed at the surface so debris gets drawn in, and when the pump stops it closes and keeps what is in the basket from floating back out.
Which skimmer is it for?
Pentair Bermuda gunite skimmers. It is the genuine Pentair part, 516315Z.
How do I know mine needs replacing?
Common signs are a weir that is cracked, stuck flat, floating too high, or missing entirely. Leaves circling the surface without being pulled in is the usual complaint.
Is it a complete part?
Yes. It is supplied as the weir gate assembly.
