What Is a Pressure Reducing Valve (PRV)?

A pressure reducing valve (PRV) controls the water pressure entering your home to keep it at a safe, consistent level.

What a PRV Does for Your Home’s Plumbing System

A pressure reducing valve (PRV), also known as a water pressure regulator, is installed on your main water line to control the pressure coming into your home from the municipal supply. In many Austin and San Antonio neighborhoods, incoming water pressure is higher than what residential plumbing systems are designed to handle.

The PRV reduces that pressure to a safe level, helping protect your pipes, fixtures, and appliances from long-term damage.

  • Prevents pipe stress: Reduces the risk of leaks and bursts
  • Protects appliances: Helps extend the life of water heaters, dishwashers, and washing machines
  • Maintains consistent pressure: Keeps water flow stable throughout your home

At Radiant, we help homeowners ensure their PRV is working properly so their entire plumbing system stays protected.
