The CMP 7-1/2" Cream Slide Valve (25831-119-750) is a 2-inch side-mount push-pull slide valve designed for pool filter backwashing on systems that use 7-1/2 inch center-to-center port spacing. This valve provides a simple way to switch between normal filtration and backwash mode, making it a practical replacement for compatible D.E. and sand filter setups.

Slide valves are commonly used on pool filtration systems because they offer straightforward operation with minimal moving parts. By pulling or pushing the handle, the valve redirects water flow to support either standard filtration or filter cleaning. When a slide valve becomes worn, cracked, or difficult to operate, it can affect water flow control and make backwashing less reliable.

Replacing the slide valve helps restore dependable filter operation and supports proper maintenance of the filtration system.

Why Slide Valves Matter

A slide valve controls the direction of water flow during normal filtration and backwashing. This is important because proper backwashing helps clean the filter media and maintain circulation efficiency.

Common problems caused by worn or damaged slide valves include:

• Difficulty switching between filter and backwash modes
• Water leakage around the valve body or handle assembly
• Reduced flow control during filter cleaning
• Worn internal seals that affect valve performance

Replacing a worn slide valve helps keep filter maintenance simple and supports proper system operation.

Designed for 2" Filter Plumbing with 7-1/2" Port Spacing

This valve is designed for 2-inch pool filter plumbing systems that use 7-1/2 inch center-to-center port spacing. It is commonly used on D.E. and sand filter systems where a side-mount push-pull backwash valve is required.

Always verify plumbing size, valve style, and port spacing before ordering to ensure compatibility with your filter system.

Push-Pull Operation for Simple Backwashing

The push-pull handle design makes this valve easy to operate during routine filter service. Pulling or pushing the handle changes the internal water path, allowing the system to switch between filtration and backwash functions without the need for a multiport valve.

This style is often preferred for its simple operation and straightforward maintenance.

Durable Construction for Pool Equipment Pads

The CMP 25831-119-750 is built for use in outdoor pool equipment environments where pressure, vibration, water exposure, and chemical contact are part of normal operation. Its durable construction is intended to provide reliable flow control and long-term service in residential pool filtration systems.

When replacing the valve, it may also be a good idea to inspect surrounding plumbing unions, filter connections, and O-rings to ensure the full backwash setup is operating correctly.
