Pressure Vacuum Breaker (PVB) Installation in Kennewick, WA
For low-hazard applications, such as lawn irrigation systems in Kennewick, WA, a pressure vacuum breaker, or PVB, is a popular and cost-effective backflow prevention device. PVBs protect against back-siphonage by letting air into the system when pressure drops. Our certified plumbers expertly install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also check for proper clearance and drainage.
Backflow Preventer Installation Cost Comparison in Kennewick, WA
A residential pressure vacuum breaker is the most affordable option, while larger RPZ assemblies for commercial buildings cost significantly more in parts and labor. Size, brand, enclosure needs and how much existing pipe must be modified all affect the price. Replacing a failed old device with a new one is often cheaper than repeated rebuilds. We give you an itemized quote that includes the initial certification test.
Double Check Valve Assembly Installation in Kennewick
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 allow. We size them to avoid too much pressure loss on your system.
Emergency Backflow Preventer Replacement in Kennewick
While installations are typically planned, sometimes an existing backflow preventer fails suddenly, creating an urgent need for replacement in Kennewick. A compromised backflow device can lead to immediate contamination risks or code violations. FHN Plumbing offers emergency replacement service to promptly assess the situation, remove the faulty unit and install a new, code-compliant backflow preventer, restoring your water safety as fast as possible.
Backflow Testing and Certification in Kennewick
Most water providers require testable backflow assemblies to be certified at installation and then once a year. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it on the spot with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Frequently Asked Questions About Backflow Preventer Installation in Kennewick
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.
Most residential backflow preventer installations can be finished within 2 to 4 hours. More complex commercial installations or those requiring extensive pipe changes might take a full day. We always aim for prompt service with minimal disruption to your water supply.
Backflow preventers are often 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 can also point to broader plumbing issues as well.
Most municipalities require annual testing of backflow preventers by a licensed, certified backflow tester. This verifies the device is working correctly and continues to protect your potable water supply from contamination. We can also assist with scheduling these annual tests.
Most residential installs take two to four hours including testing. Large commercial assemblies can take a full day, especially if piping must be reconfigured.
It depends on the hazard and local rules. Irrigation often uses a PVB or double check, while high hazard connections like commercial kitchens or chemical injection require an RPZ.
Most manufacturers offer one to five year warranties depending on the model. We also warranty our installation labor and will review the coverage with you.
Backflow preventers are installed at cross-connection points where non-potable water could enter the potable water supply. Common locations include irrigation system connections, fire sprinkler lines, boiler systems and connections to auxiliary water supplies, often just after the main water meter or at the point of hazard.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
