INSTALLATION & USE
Installing the CV14S-MxM Check Valve
- Shut off water supply and relieve system pressure before installation
- Apply thread sealant tape to male 1/4" MNPT threads on both sides of the valve
- Thread the check valve into your system with flow direction matching the arrow on the valve body
- Hand-tighten, then use a wrench to snug an additional quarter turn—do not overtighten
- Restore water pressure slowly and inspect connections for leaks
COMPATIBILITY
System Integration
The Hydronamic CV14S-MxM check valve works with reverse osmosis systems, booster pumps, water filtration equipment, and any application requiring backflow prevention with 1/4" male NPT fittings. Ideal for preventing reverse flow from storage tanks, protecting pump seals, and isolating system stages. Compatible with potable water applications and suitable for use with standard municipal water supplies.
🔧 Pro Tip: Install check valves after booster pumps and before storage tanks to prevent backflow that can damage pump internals and cause pressure fluctuations during system shutdown.
