Proper water flow through a pool skimmer is critical for both surface cleaning and pump protection. When water levels drop or skimmer flow becomes restricted, a pool pump can begin pulling air instead of water, leading to loss of prime, overheating, and potential pump damage. The CMP Pool Skimmer Float Valve (25140-000-700) is designed to automatically regulate suction inside in-ground pool skimmers, helping maintain safe, consistent water flow to the pump.

This float valve sits inside the skimmer and responds to changing water levels. When the water level is normal, it allows balanced suction between the skimmer and main drain. If the water level drops too low, the float valve closes off skimmer suction and redirects flow to the main drain, preventing air from entering the system. This automatic response protects the pump without requiring manual adjustment.

This is a purpose-built pool safety component, not an optional accessory.

Why a Skimmer Float Valve Is Essential

Pool pumps are designed to move water, not air. When a skimmer begins to draw air due to low water level, clogged baskets, or heavy surface debris, the pump can lose prime and run dry. Even short periods of dry running can cause seal failure, overheating, and premature pump wear.

The CMP skimmer float valve acts as a safeguard, maintaining suction integrity and protecting expensive equipment. It also improves circulation balance by ensuring the pump always has a reliable water source.

Designed for In-Ground Pool Skimmer Systems

This float valve is designed specifically for in-ground pool skimmers that use a float-style suction control system. It installs directly into compatible skimmer bodies and operates automatically without electronics or adjustments.

Because it is molded to proper tolerances, it moves freely within the skimmer and seals correctly when water levels drop, providing dependable operation over time.

Built for Continuous Pool Operation

The CMP Pool Skimmer Float Valve is manufactured from durable pool-grade materials designed to withstand constant water exposure, chemical treatment, and temperature changes. Its simple mechanical design makes it reliable and low-maintenance.

For service professionals, it helps prevent pump damage complaints. For pool owners, it provides peace of mind during hot weather, evaporation, or temporary water loss situations.

When to Use the CMP Pool Skimmer Float Valve

This skimmer float valve is recommended when:

• The pool has an in-ground skimmer with a float-style valve system

• Water levels may drop due to evaporation or splash-out

• Protecting the pump from running dry is a priority

• Skimmer suction needs to balance safely with the main drain

• Replacing a worn, stuck, or missing float valve

Installing a functioning float valve is a simple step that can prevent costly pump repairs.

Practical Protection for Pool Owners and Service Professionals

For pool owners, this float valve provides automatic pump protection without daily monitoring. For service professionals, it is a critical component that helps prevent callbacks related to pump priming issues or dry-running damage.

A properly functioning skimmer float valve keeps circulation stable and protects the heart of the pool system.
