Frequently Asked Questions About Backflow Preventer Installation in Yakima
The cost for backflow preventer installation in Yakima, WA typically ranges from $400 to $1,500, depending on the type of device, its size and the complexity of the installation. A basic residential PVB for an irrigation system is generally on the lower end, while a commercial-grade RPZ assembly costs more because of material and labor requirements.
Backflow is when water flows the wrong way through a pipe and carries contaminants into the clean water supply. It can happen from back siphonage during a pressure drop or back pressure from pumps and other equipment.
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 help with scheduling these annual tests.
You likely 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 Yakima often mandate these devices for certain applications to protect public health.
Installing a backflow preventer is a complex task that requires plumbing knowledge, tools and certification to meet local codes and effectively protect your water supply. Incorrect installation can lead to ineffective protection, fines or health risks. It is always recommended to hire a licensed professional like FHN Plumbing.
FHN 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 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.
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.
