Slide valves play a critical role in DE filter operation by directing water flow during normal filtration and backwashing. When a slide valve becomes stiff, leaks internally, or fails to seal correctly, filter performance is compromised and water may bypass the filtration system entirely. The CMP P-Style Slide Valve Internal Assembly is a complete internal replacement designed to restore proper function to compatible P-style slide valves used on DE pool filters.

This internal assembly replaces the moving internal components responsible for sealing and flow direction inside the valve body. Rather than replacing the entire valve housing, this repair part allows pool owners and service professionals to restore reliable valve operation while reusing the existing external plumbing connections.

Designed for durability and OEM-correct fit, this replacement assembly helps return DE filtration systems to proper working order.

Restores Proper Valve Sealing and Operation

Over time, internal slide valve components wear due to pressure changes, repeated backwashing cycles, and chemical exposure. When internal seals fail, water may leak past the valve or bypass the filter grids, reducing filtration efficiency.

The CMP P-Style Slide Valve Internal Assembly restores correct internal sealing and smooth valve movement. Once installed, it allows the valve to switch cleanly between filtration and backwash modes, ensuring water flows through the filter media as intended.

This repair is often the preferred solution when external valve bodies remain in good condition.

Designed for CMP P-Style Slide Valve Compatibility

This internal assembly is manufactured specifically for CMP P-style slide valves used on DE filter systems. Proper fitment ensures correct alignment within the valve housing, maintaining reliable sealing and smooth operation.

Using the correct internal assembly helps prevent leaks, sticking handles, and incomplete valve engagement.

Durable Construction for Demanding Filter Environments

Slide valve internals are exposed to constant water pressure, chemical-treated water, and mechanical movement. The CMP internal assembly is constructed from durable, chemical-resistant materials designed to withstand these conditions without deforming or degrading prematurely.

This durability supports long-term valve reliability and reduces the need for repeated repairs.

Why Replacing Slide Valve Internals Matters

Worn or damaged slide valve internals can affect the entire filtration system.

Replacing the internal assembly helps:

• Restore proper filtration and backwash flow paths

• Prevent internal bypass and water leakage

• Improve DE filter performance and efficiency

• Extend the service life of the slide valve

Addressing internal valve issues early helps avoid more extensive plumbing or filter repairs.
