Double Check Valve Assembly (DCVA) Installation in Idaho Falls
The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe.

Our certified plumbers carefully install these devices, making sure both check valves operate correctly and are properly sealed to prevent backpressure or back-siphonage into the main water supply.

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.

Frequently Asked Questions About Backflow Preventer Installation in Idaho Falls
Residential pressure vacuum breakers typically cost $250 to $700 installed. Double check and RPZ assemblies for larger homes or businesses range from $800 to $3,500 or more depending on size and enclosure needs.
Constant dripping or discharge from an RPZ relief valve, low pressure downstream and a failed annual test are common signs. Visible corrosion or a cracked body from freezing also means service is needed.
We regularly install high-quality backflow preventers from trusted brands such as Watts, Wilkins by Zurn, Apollo and Conbraco. Our plumbers are experienced with a wide range of devices and can recommend the best option for your application and budget.
Most residential installs take two to four hours including testing. Large commercial assemblies can take a full day, especially if piping must be reconfigured.
We install all common types of backflow preventers, including reduced pressure zone assemblies, pressure vacuum breakers and double check valve assemblies. Our team will recommend the appropriate device based on your property's hazard level and local plumbing codes in Idaho Falls.
HNV Plumbing stands behind our work with a comprehensive warranty on our backflow preventer installations. This warranty covers both the labor and the installed device, providing you with peace of mind. Specific warranty details will be provided with your quote.
Backflow preventers are usually installed as a preventive measure or because code requires them. Signs of possible cross-contamination include discolored or foul-smelling tap water, unexplained drops in water pressure or visible dirty water entering a clean water source, though these often point to broader plumbing issues as well.
In Idaho Falls, most backflow preventers must be tested once a year by a certified backflow tester to confirm they are working correctly and providing adequate protection. This is a separate service from installation but is essential for ongoing compliance and safety.
