Quick overview

  • Genuine Pentair Factory part number 513352 for the HydroSkim skimmer.
  • Weir door only This is the flap itself, not a complete skimmer.
  • Speeds up the surface The weir narrows the opening so water accelerates across it and pulls floating debris in.
  • Traps what it catches Once the pump stops, the weir swings shut and keeps leaves from floating back out of the throat.
  • A visible failure A weir that has cracked at the hinge or gone missing shows up as leaves drifting back onto the pool.
  • Check the water level A weir only works when the water sits at the middle of the skimmer mouth, so set the level before blaming the part.

Product details

Pentair 513352 is the weir door for HydroSkim skimmers. It is the genuine Pentair replacement for the hinged flap in the skimmer throat.

What the weir actually does

The weir is a small hinged door that floats against the water surface. By narrowing the skimmer opening, it makes water accelerate as it crosses the lip, and that faster sheet of water is what drags leaves and film off the surface instead of letting them drift past. When the pump shuts off, the weir falls closed and holds everything it collected inside the skimmer rather than releasing it back onto the pool.

Signs it needs replacing

Leaves that reappear on the surface after the pump stops, a flap that has cracked at the hinge, or a weir that no longer swings freely all point at this part. Before you order, confirm the water level sits around the middle of the skimmer mouth. A weir riding too high or too low cannot do its job no matter how good it is.

Questions and answers

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

What does the weir do?
It is the hinged flap in the skimmer throat. It narrows the opening so surface water speeds up and carries floating debris in, and it swings closed when the pump stops so the debris stays put.
Which skimmer is this for?
Pentair HydroSkim skimmers.
My skimmer keeps letting leaves back out, is this the fix?
If the weir is cracked, stuck or missing, yes. Also check that the water level sits around the middle of the skimmer mouth, because a weir cannot work at the wrong level.
Is this the whole skimmer?
No. It is the weir door on its own.
