CMP Pool Skimmer Float Valve – In-Ground Models | 25140-000-700
Automatic Protection for Your Pump & Perfect Surface Skimming
Keep your pool running smoothly and your pump protected with the CMP Pool Skimmer Float Valve – 25140-000-700. Designed for in-ground skimmer systems, this replacement float valve automatically regulates the flow of water between your skimmer and main drain, helping to maintain consistent circulation, protect your pump from air damage, and ensure more efficient debris removal from the pool surface.
Whether you're replacing a worn-out valve or upgrading your system for improved performance, the CMP float valve is an essential part of a properly balanced pool. It's a small component that plays a big role in system protection, energy efficiency, and long-term maintenance savings.
Prevents Pump Damage from Low Water Conditions
One of the biggest threats to pool pumps is running dry. If your pool water level drops—due to evaporation, splashing, or neglect—and the skimmer begins pulling air instead of water, it can severely damage your pump motor. That’s where the CMP 25140-000-700 Float Valve shines.
This smart component uses a built-in float mechanism to automatically redirect suction from the skimmer to the main drain if the water level gets too low. By maintaining a safe flow of water into your system, it protects your pump from airlock, cavitation, and burnout.
This simple feature can save hundreds of dollars in pump repairs and replacements, making it one of the most cost-effective safety components in your entire pool plumbing system.
Balances Suction Between Skimmer & Main Drain
Optimal circulation means drawing from both the skimmer and the main drain—but balancing this flow can be tricky without a float valve. The CMP float valve ensures that suction is properly split between the surface and bottom of your pool, giving you a cleaner surface and improved water clarity throughout.
It helps skim off leaves, bugs, and surface oils faster while also promoting better chemical distribution and heating. This results in more consistent chlorine levels, fewer algae blooms, and less time spent manually skimming or brushing the pool.
High-Quality Build for Long-Term Use
Manufactured by CMP (Custom Molded Products), a trusted name in pool parts and components, this float valve is made from high-strength thermoplastics designed to resist corrosion, UV degradation, and wear from chlorine or saltwater exposure. The internal float is equally durable, ensuring dependable performance season after season.
Whether you’re maintaining a high-use community pool or a private backyard oasis, this float valve is built to withstand daily use and harsh pool environments without failure.
Easy to Replace & Compatible with Standard Skimmers
The 25140-000-700 model is designed to fit most common in-ground pool skimmers, including CMP, Hayward, and similar models that use a dual-port bottom design. It drops right into the skimmer housing and connects directly to the equalizer line and main drain line, providing a tight and secure fit without tools.
Installation is typically as easy as:
-
Removing the skimmer lid and basket
-
Pulling out the old float valve (if applicable)
-
Inserting the CMP replacement valve into the skimmer base
-
Verifying a snug fit and proper float movement
No glue, threading, or tools are needed—just a quick drop-in installation.
Energy Efficiency and Filter Performance
An often-overlooked benefit of proper skimmer function is energy efficiency. When your float valve helps balance suction and reduce air intake, your pump and filter system work more smoothly, drawing in less air and filtering more water with each cycle.
This improves overall filtration, extends the life of your pool equipment, and can even reduce your monthly energy bill by decreasing strain on your pump motor.
Additionally, a properly functioning skimmer and float valve combo helps trap debris in your skimmer basket before it reaches the filter, minimizing clogging and extending the time between cleanings.
