Reduced Pressure Zone (RPZ) Assembly Installation in Kent
RPZ assemblies offer the highest level of backflow protection and are often required for high-hazard applications in Kent. These devices feature two independent check valves and a relief valve that opens to discharge water if pressure differentials indicate a backflow condition. FHN Plumbing focuses on precise RPZ installation, with proper sizing, placement and testing to meet all regulatory requirements for residential and commercial properties. We work with top brands like Watts and Febco.

Pressure Vacuum Breaker (PVB) Installation in Kent, WA
For low-hazard applications, such as lawn irrigation systems in Kent, 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 carefully install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also make sure of proper clearance and drainage.
Pool and Spa Fill Backflow Protection in Kent, WA
An auto-fill line or hose connection on a pool or spa creates a straight path for chlorinated water to reach the supply. We install the correct device on pool fill lines and check that hose bibbs have vacuum breakers. This simple step protects your household water and keeps you in line with local code. We can add the work when a pool is being built or remodeled.
Double Check Valve Assembly Installation in Kent
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.
Reduced Pressure Zone (RPZ) Device Installation in Kent, WA
For high-hazard applications in Kent, WA 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. FHN Plumbing specializes in 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 Kent, WA
Commercial properties in Kent, WA often have complex plumbing systems that pose a higher risk of cross-contamination and require robust backflow prevention. Restaurants, hospitals, industrial facilities and even multi-family buildings must comply with commercial plumbing codes. FHN Plumbing provides complete installation of heavy-duty backflow preventers, including large diameter RPZ assemblies, to safeguard public health and meet Washington regulations for businesses. We handle all required permits and inspections.
Backflow Prevention for Irrigation Systems in Kent, WA

Frequently Asked Questions About Backflow Preventer Installation in Kent
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.
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.
An RPZ, or reduced pressure zone device, provides the highest level of protection and is used for high-hazard applications where contaminants could be toxic. A DCVA, or double check valve assembly, is used for low-hazard applications where contaminants are non-toxic. The choice depends on the risk of contamination at the cross-connection point.
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.
You probably need a backflow preventer if you have an irrigation system, a fire sprinkler system, a swimming pool or any auxiliary water source that connects to the main water supply. Local regulations in Kent often mandate these devices for certain applications to protect public health.
Most residential backflow preventer installations can be finished within 2 to 4 hours. More complex commercial systems or installations requiring significant pipe changes might take longer. We always aim to complete the work promptly while keeping our quality standards high.
We install backflow preventers from leading manufacturers known for quality and reliability. Our go-to brands include Watts, Febco, Zurn and Apollo, so you receive a durable, effective device that meets all industry standards.
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 can also point to broader plumbing issues as well.
