CMP B-38 Floating Weir – Replacement Weir Door (B38) for Pool Skimmers
The CMP B-38 Floating Weir (B38) is a direct replacement skimmer weir designed to restore proper surface skimming and debris control in residential swimming pools. Installed inside the skimmer throat, the floating weir regulates water flow into the skimmer while preventing leaves and debris from washing back into the pool when the pump cycles off.
Manufactured by Custom Molded Products (CMP), this weir is built to OEM standards for fit and durability. Its balanced buoyancy allows the door to open and close smoothly with changing water levels, helping maintain consistent suction and improving overall circulation efficiency.
Replacing a worn, warped, or brittle weir door helps your skimmer operate as intended, keeping surface debris moving toward the filter and reducing strain on your pool’s circulation system.
Why the Floating Weir Matters
A properly functioning weir is essential for effective surface cleaning.
Why this matters:
-
Maintains steady skimmer suction and water flow
-
Prevents debris from floating back into the pool
-
Supports efficient circulation and filtration performance
Even a small weir failure can significantly reduce skimmer effectiveness.
Durable, Pool-Grade Construction
The CMP B-38 Floating Weir is molded from chlorine-resistant, UV-stabilized plastic designed to withstand constant exposure to sunlight, chemicals, and outdoor conditions. This construction helps prevent cracking, warping, and fading over time.
Its smooth hinge action and floating design ensure reliable operation throughout daily pump cycles.
Easy, Tool-Free Installation
This weir is designed for quick replacement and installs easily without tools, adhesives, or hardware. Most pool owners or service technicians can complete installation in minutes during routine skimmer maintenance.
Always measure your existing weir or skimmer opening to confirm compatibility before purchase.
