Commercial Backflow Preventer Installation in Lakewood
Restaurants, salons, dental offices and light industrial buildings often need multiple backflow devices on soda machines, boilers, dishwashers and process water. We survey the building, identify each cross-connection and install containment and isolation assemblies as required. Work is scheduled after hours or on weekends when needed to keep from shutting down your business. You receive documentation for each device for your records and your water utility.

Reduced Pressure Zone (RPZ) Device Installation in Lakewood, WA
For high-hazard applications in Lakewood, 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 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 critical for effective operation.
Double Check Valve Assembly Installation in Lakewood
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 excessive pressure loss on your system.
Residential Backflow Preventer Installation in Lakewood
For homeowners in Lakewood, protecting your family's drinking water is paramount. We install many types of backflow preventers, often required for irrigation systems, fire suppression lines or properties with alternative water sources. Our plumbers will assess your home's plumbing layout to recommend the right device, meeting local health department regulations and protecting your potable water supply. We handle everything from small residential devices to larger systems.
Backflow Preventer Installation Cost Comparison in Lakewood, WA
A residential pressure vacuum breaker is the most affordable option, while larger RPZ assemblies for commercial buildings cost a good deal 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 usually cheaper than repeated rebuilds. We give you an itemized quote that includes the initial certification test.
Irrigation Backflow Preventer Installation in Lakewood
Landscape irrigation is the most common reason homeowners need a backflow device. Fertilizer, herbicides and stagnant water in sprinkler and drip lines can be siphoned into your drinking water if pressure drops. We install pressure vacuum breakers or double check assemblies based on local requirements and the design of your system. Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.
Reduced Pressure Zone (RPZ) Assembly Installation in Lakewood
RPZ assemblies offer the highest level of backflow protection and are commonly required for high-hazard applications in Lakewood. 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 specializes in 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.
