Pool and Spa Fill Backflow Protection in Lawrence, KS
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.

Irrigation Backflow Preventer Installation in Lawrence
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.
Backflow Enclosures and Freeze Protection in Lawrence, KS
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Many Kansas homeowners let faucets drip and open cabinet doors on the coldest nights to keep water moving. We install insulated enclosures, freeze blankets or heated cabinets based on your location. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and service.
Reduced Pressure Zone Assembly Installation in Lawrence, KS
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 trusted brands like Watts, Febco, Wilkins and Apollo.
Backflow Testing and Certification in Lawrence
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 on the spot with genuine parts. We submit passing results so you avoid compliance letters or service interruption.
Reduced Pressure Zone (RPZ) Assembly Installation in Lawrence
RPZ assemblies offer the highest level of backflow protection and are commonly required for high-hazard applications in Lawrence. These devices feature two independent check valves and a relief valve that opens to discharge water if pressure differentials indicate a backflow condition. KRV 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 trusted brands like Watts and Febco.
Commercial Backflow Prevention in Lawrence, KS
Commercial properties in Lawrence, KS often have complex plumbing systems that pose a higher risk of cross-contamination and need robust backflow prevention. Restaurants, hospitals, industrial facilities and even multi-family buildings must comply with commercial plumbing codes. KRV Plumbing provides complete installation of heavy-duty backflow preventers, including large diameter RPZ assemblies, to safeguard public health and meet Kansas' regulations for businesses. We handle all necessary permits and inspections.

Pressure Vacuum Breaker (PVB) Installation in Lawrence, KS
For low-hazard applications, such as lawn irrigation systems in Lawrence, KS, 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 expertly install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also make sure of proper clearance and drainage.
