Backflow Testing and Certification in Porterville
Most water providers require testable backflow assemblies to be certified at installation and then once a year. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Backflow Enclosures and Freeze Protection in Porterville, CA
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Mountain and foothill homes in Northern California see real winters, so pipes there need insulation, heat tape, or careful draining when a cabin sits empty. We install insulated enclosures, freeze blankets or heated cabinets based on your local climate. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and repairs.
Double Check Valve Assembly (DCVA) Installation in Porterville
The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Porterville, 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.
Pressure Vacuum Breaker (PVB) Installation in Porterville, CA
For low-hazard applications, such as lawn irrigation systems in Porterville, CA, a pressure vacuum breaker, or PVB, is a common 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 check for proper clearance and drainage.
Reduced Pressure Zone Assembly Installation in Porterville, 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 easily. We carry proven brands like Watts, Febco, Wilkins and Apollo.
Double Check Valve Assembly Installation in Porterville
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.
Pool and Spa Fill Backflow Protection in Porterville, CA
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 renovated.

Irrigation Backflow Preventer Installation in Porterville
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.
