RPZ assemblies protect against high-hazard cross-connections at restaurants, medical offices, car washes and buildings with chemical feed systems.

Proper drainage is planned for the relief port discharge.

Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides.

Insulated covers or enclosures help protect it from weather and theft.

Frequently Asked Questions About Backflow Preventer in Lawrence
Annual residential backflow testing typically costs $75 to $150 per assembly. Repairs with a rebuild kit usually run $150 to $450. New residential installation ranges from $300 to $1,200, and commercial RPZ assemblies often cost $1,500 to $5,000 installed.
A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan. Most Indiana homeowners disconnect hoses and shut off outdoor spigots before winter, and many add pipe insulation or heat tape to vulnerable runs. Regular testing and maintenance help extend its service life.
Backflow prevention is essential because of changing water pressures, main breaks and fire flow that can drop pressure suddenly, and the potential for cross-connections from irrigation systems or industrial processes. These factors increase the risk of contaminated water entering the public supply, making a working backflow preventer essential.
