RPZ Testing & Installation in Hot Springs, AR

Certified Backflow Prevention Services for Residential & Commercial Customers

Anchor Plumbing offers professional RPZ testing, installation, and inspection services for residential, commercial, and new construction properties. Backflow prevention is essential for keeping your water supply safe from contaminants, especially in systems connected to irrigation, fire suppression, or commercial equipment.


Our licensed technicians ensure your Reduced Pressure Zone (RPZ) valve is compliant with all local and state codes.

What Is an RPZ Valve and Why Is Testing Important?


An RPZ backflow prevention device is designed to protect your potable water system from contamination caused by backflow. If pressure changes cause water to reverse direction, dangerous substances like fertilizers, chemicals, or bacteria can be siphoned into the main supply.


Routine RPZ valve testing is required by law in many municipalities to ensure the device is working properly. Anchor Plumbing is fully certified to perform these tests.
