Protect your reverse osmosis system with the LiquaGen Pressure Reducer Valve (PRV). Designed to regulate incoming water pressure, this valve helps prevent leaks, housing cracks, and premature filter damage caused by high city water pressure.
Compatible with all standard RO systems and water filtration brands.
1/4" Push Connect
Fits most residential reverse osmosis systems, under-sink filters, refrigerator lines, and inline filtration setups.
High incoming water pressure can:
Crack filter housings
Cause O-ring leaks
Damage RO membranes
Shorten filter lifespan
Create constant dripping at fittings
Installing a PRV before the first filter housing protects your entire system and ensures stable performance.
We offer 3 pressure options to match your setup:
Ideal for homes with very high city pressure (80–120 PSI).
