Backflow Preventer Brands We Install in Madison
HKV Plumbing works with leading backflow preventer brands known for reliability and durability. We regularly install devices from manufacturers such as Watts, Wilkins by Zurn, Apollo and Conbraco. Our experience with these brands means you receive a high-quality, long-lasting solution built to handle the water conditions and pressures in Madison plumbing systems. We can also advise on models that best fit your budget and application.
Backflow Testing and Certification in Madison
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.
Pool and Spa Fill Backflow Protection in Madison, WI
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.
Reduced Pressure Zone (RPZ) Assembly Installation in Madison
RPZ assemblies offer the highest level of backflow protection and are often required for high-hazard applications in Madison. These devices feature two independent check valves and a relief valve that opens to discharge water if pressure differentials indicate a backflow condition. HKV 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.

Backflow Preventer Installation Cost Comparison in Madison, WI
A residential pressure vacuum breaker is the most affordable option, while larger RPZ assemblies for commercial buildings cost significantly more in parts and labor. Size, brand, enclosure needs and how much existing pipe must be modified all affect the price. Replacing a failed old device with a new one is usually cheaper than repeated rebuilds. We give you an itemized quote that includes the initial certification test.
