Applications

Designed for both residential and commercial pool and spa systems, the CMP HydroSeal check valve ensures one-way water flow in circulation, heating, or chemical feed systems. It’s ideal for use in return lines, heater bypass loops, and salt or chlorination systems where backflow prevention is essential.

Installation Instructions

• Turn off the pump and relieve system pressure before installation.
• Check the flow direction arrow on the valve body before connecting to plumbing.
• Use PVC primer and solvent cement for secure, watertight joints.
• Install the valve in a horizontal or vertical position as required by the plumbing layout.
• Tighten the clear lid by hand until snug; avoid over-tightening.
• After installation, restore system pressure and verify that the valve opens and closes correctly.

Troubleshooting

• Water leaking backward: Check for debris on the seal or spring assembly; clean or replace if worn.
• Reduced flow: Inspect for obstruction inside the valve or verify correct orientation with flow direction.
• Lid leak: Ensure the lid O-ring is seated properly and free from dirt or damage.

Maintenance Tip

Inspect the valve periodically for debris or wear. Clean the internal seal and spring assembly as needed, and replace any worn parts to maintain consistent backflow prevention. Always recheck lid tightness after servicing to ensure proper operation and leak-free performance.
