The CMP P-Style Slide Valve Internal Assembly (25831-004-172) is a precision replacement internal component designed for CMP P-Style slide valves used in pool and spa plumbing systems. This internal assembly controls water flow direction within the valve body, allowing the valve to open, close, or divert flow as intended during normal system operation.

Over time, internal slide valve components are subject to wear from constant water pressure, chemical exposure, and repeated operation. When the internal assembly becomes worn or damaged, valves may become difficult to operate, fail to seal properly, or allow water to bypass, leading to reduced efficiency or leaks. Replacing the internal assembly restores smooth valve operation and proper sealing without requiring full valve replacement.

Manufactured by CMP, this internal assembly is built to match original specifications for P-Style slide valves, ensuring correct fit, alignment, and long-term reliability in pool circulation systems.

Why the Internal Valve Assembly Matters

The internal components of a slide valve directly affect how well the valve controls water flow. A worn internal assembly can compromise system performance and place unnecessary stress on pumps and plumbing.

Why this matters:

• Restores proper sealing and flow control

• Prevents internal bypass and pressure loss

• Improves valve operation and reliability

• Helps extend the life of existing valve housings

• Reduces the risk of leaks and circulation issues

Replacing internal valve components early helps maintain consistent system performance and avoids more costly repairs.

Designed for CMP P-Style Slide Valves

This internal assembly is specifically designed for CMP P-Style slide valves. Proper compatibility is critical, as internal valve components must align precisely within the valve body to ensure smooth movement and effective sealing.

Using manufacturer-matched replacement parts helps preserve correct tolerances and ensures the valve operates as designed.

Durable Construction for Pool Environments

CMP engineers this internal assembly using materials suitable for continuous exposure to pool water, pressure, and chemical conditions. The components are designed to resist deformation, chemical degradation, and premature wear, even in demanding residential or commercial pool systems.

Its construction supports consistent operation through repeated open and close cycles.

Installation & Service Notes

For best results:

• Shut off pump power and relieve system pressure before service

• Disassemble the valve according to manufacturer instructions

• Remove worn internal components

• Install the new internal assembly, ensuring correct orientation

• Reassemble valve and test operation before returning system to service

Professional installation is recommended if unfamiliar with valve servicing.
