Residential Backflow Preventer Installation in Olympia
For homeowners in Olympia, 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 bigger systems.

Backflow Prevention for Irrigation Systems in Olympia, WA
Irrigation systems in Olympia, WA 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 specialize 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.
Pool and Spa Fill Backflow Protection in Olympia, WA
An auto-fill line or hose connection on a pool or spa creates a direct 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 (DCVA) Installation in Olympia
The double check valve assembly, or DCVA, is a common backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Olympia, DCVAs are often installed on fire sprinkler systems or irrigation lines. 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.

We handle all necessary permits and inspections.
Double Check Valve Assembly Installation in Olympia
Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines.

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.
