CMP Pool Skimmer Float Valve – In-Ground Models | 25140-000-700
Maintain Proper Water Flow and Prevent Pump Damage
Keep your pool system running smoothly with the CMP Pool Skimmer Float Valve (25140-000-700)—a precision-engineered replacement designed for in-ground pool skimmers. This automatic flow control valve helps regulate suction between your pool’s skimmer and main drain, maintaining consistent water flow to your pump and protecting it from running dry.
Built from durable materials and designed to fit most CMP® in-ground skimmer bodies, this genuine replacement part ensures long-lasting reliability and easy installation for homeowners and service professionals alike.
What the Float Valve Does — and Why It’s Important
The skimmer float valve plays a critical role in your pool’s circulation system. Located at the bottom of the skimmer well, it automatically adjusts suction flow to ensure your pump always draws water—even if your skimmer basket becomes clogged or water levels drop.
Key functions include:
-
Maintaining continuous suction to prevent pump starvation.
-
Balancing flow between the skimmer and main drain.
-
Sealing off the skimmer line when the water level is low.
-
Protecting your pump and motor from running dry.
Without a properly functioning float valve, your pump can overheat or lose prime—leading to costly repairs or system shutdowns.
Designed for CMP In-Ground Skimmers
The CMP 25140-000-700 Float Valve is a genuine replacement for CMP’s popular in-ground skimmer models. It fits directly into the skimmer well with a snug, watertight fit and requires no special tools for installation.
Compatible with the following CMP models and equivalent systems:
-
CMP In-Ground Skimmer Series 25141 and 25142
-
Hayward®-style in-ground skimmers with similar configurations
-
Other skimmer bodies accepting standard float valve dimensions
If your original skimmer valve shows signs of wear, cracking, or sticking, this is the correct replacement part to restore reliable operation.
Premium Materials for Long-Term Durability
Manufactured from chemical- and UV-resistant ABS plastic, the CMP Float Valve withstands constant exposure to chlorinated water, sunlight, and fluctuating temperatures. Its precision-balanced float disc and corrosion-proof spring components ensure smooth motion and airtight sealing during operation.
Every CMP valve is built for years of consistent performance—no sticking, warping, or premature failure.
Easy Installation and Maintenance
Replacing your skimmer float valve is simple and requires no plumbing modifications.
-
Turn off your pool pump.
-
Remove the skimmer lid and basket.
-
Lift out the old valve assembly.
-
Insert the new CMP Float Valve (25140-000-700) into the skimmer well.
-
Replace the basket and restart your system.
The valve will automatically begin regulating water flow between the skimmer and main drain as your pump operates.
For best results, inspect your valve regularly and keep the skimmer basket free of large debris that could obstruct the flow path.
Prevents Pump Damage During Low Water Levels
If your pool’s water level drops too low—due to evaporation, splash-out, or leaks—the float disc inside the valve rises automatically, sealing off the skimmer line and forcing suction to draw from the main drain instead.
This automatic protection prevents your pump from losing prime or drawing air, keeping your system safe even when you’re not there to monitor it.
Compatible with Most 1.5” and 2” Suction Lines
The CMP Float Valve Assembly fits standard suction plumbing configurations commonly found in residential in-ground pools. Its dual-port design manages flow between the skimmer suction port and the equalizer or main drain line, ensuring proper balance for consistent circulation.
If you have a dual-suction setup or an equalizer line, this valve is an essential part of maintaining system efficiency and safety.
