Our experience with these brands means you receive a high-quality, long-lasting solution built to withstand the water conditions and pressures in Ammon plumbing systems. We can also advise on models that best fit your budget and application.

Double Check Valve Assembly Installation in Ammon
Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines. They have two spring-loaded check valves and test cocks for annual certification. Unlike an RPZ, they do not discharge water, so they can be installed in vaults or below grade where local rules permit. We size them to avoid too much pressure loss on your system.
Pressure Vacuum Breaker (PVB) Installation in Ammon, ID
For low-hazard applications, such as lawn irrigation systems in Ammon, ID, a pressure vacuum breaker, or PVB, is a common and cost-effective backflow prevention device. PVBs protect against back-siphonage by letting air into the system when pressure drops. Our certified plumbers carefully install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also check for proper clearance and drainage.
Reduced Pressure Zone (RPZ) Device Installation in Ammon, ID
For high-hazard applications in Ammon, ID where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is often required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops. HNV Plumbing is experienced with RPZ installation, making sure all components are correctly sized, positioned and set up according to state and local plumbing codes. Proper installation is essential for effective operation.
Commercial Backflow Prevention in Ammon, ID
Commercial properties in Ammon, ID often have complex plumbing systems that pose a higher risk of cross-contamination and need robust backflow prevention. Restaurants, hospitals, industrial facilities and even multi-family buildings must comply with commercial plumbing codes. HNV Plumbing provides full installation of heavy-duty backflow preventers, including large diameter RPZ assemblies, to safeguard public health and meet Idaho regulations for businesses. We handle all necessary permits and inspections.
Backflow Prevention for Irrigation Systems in Ammon, ID
Irrigation systems in Ammon, ID are a frequent source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply. Installing a dedicated backflow preventer for your sprinkler system is often a local code requirement. We are experienced in selecting and installing the correct device, such as a pressure vacuum breaker or atmospheric vacuum breaker, to protect your home's main water line from contaminants coming from your landscape irrigation.
Code-Compliant Backflow Installation in Ammon, ID
Navigating the plumbing codes for backflow prevention in Ammon, ID can be challenging. HNV Plumbing stays up to date with local and state regulations so every installation is fully compliant. Idaho uses the Uniform Plumbing Code as its statewide basis, with permits and inspections handled by the state or by local jurisdictions. From proper device selection and placement to required permits and inspections, we handle every part of code compliance. Your system works as intended and avoids fines or expensive rework down the line.

Reduced Pressure Zone Assembly Installation in Ammon, ID
RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested easily. We carry trusted brands like Watts, Febco, Wilkins and Apollo.
