CMP HydroSeal 2" Socket Union Serviceable Check Valve | CPVC 25830-734-000

Protect your pool equipment from backflow with the CMP HydroSeal 2" Serviceable Check Valve. Engineered for high-performance and durability, this 25830-734-000 model features a unique union design that allows for easy internal access and cleaning without ever having to cut into your plumbing. Made from high-temp black CPVC, it is ideal for demanding applications like spa spillovers and plumbing lines between chlorinators and heaters.

Key Features

• Serviceable Design: The threaded union locking nut allows you to quickly remove the internal assembly for cleaning or flapper replacement without disturbing the pipe connections.
• High-Heat CPVC Construction: Built to withstand higher temperatures and pressure (up to 50 psi), making it the perfect choice for heater discharge lines.
• Corrosion-Resistant Hardware: Features a premium spring and pin designed to resist harsh pool chemicals, ensuring a long-lasting, watertight seal.
• Full Flow Porting: The 2-inch socket connections provide a large internal diameter to minimize flow resistance and keep your pump running efficiently.
• Clear Lid Compatibility: Compatible with CMP clear-view lids (sold separately) for instant visual inspection of the internal flapper.
