Irrigation Backflow Preventer Installation in South Gate
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 layout 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 Assembly Installation in South Gate, CA
RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested. We carry proven brands like Watts, Febco, Wilkins and Apollo.

Frequently Asked Questions About Backflow Preventer Installation in South Gate
Residential pressure vacuum breakers usually 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.
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 South Gate often require these devices for certain applications to protect public health.
Signs of a failing backflow preventer include discolored or foul-smelling water, a noticeable drop in water pressure, visible leaks around the device or water discharging from the relief valve on an RPZ. If you notice any of these, contact us for an inspection in South Gate.
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 comes down to the risk of contamination at the cross-connection point.
