Reduced Pressure Zone Assembly Service in St. Joseph, MO
RPZ assemblies protect against high-hazard cross-connections at restaurants, medical offices, car washes and buildings with chemical feed systems. They have two check valves and a relief port that discharges water if a check fails. We install, test and rebuild RPZ units from Watts, Febco, Wilkins and Apollo. Proper drainage is planned for the relief port discharge.
Annual Backflow Testing in St. Joseph
Most water providers require backflow assemblies to be tested at least once a year. Our certified testers connect a calibrated differential pressure gauge and check each check valve and relief valve. Test results are recorded on the provider's form and submitted for you. If the assembly passes, you are all set until next year.
Fire Line Backflow Testing in St. Joseph
Fire sprinkler systems typically use double check or double check detector assemblies to keep stagnant water out of the public supply. These assemblies need regular testing, often coordinated with fire system inspections. We test and repair fire line assemblies and document the results. We can coordinate scheduling with your fire protection contractor.

Backflow Preventer Repair and Rebuild in St. Joseph, MO
Common failures include worn check valve rubbers, debris stuck under seats and relief valves that drip constantly.

Signs of a failing backflow preventer include discolored water, unusual tastes or odors in your water, water leaking from the relief valve, or a sudden drop in water pressure. If you notice any of these issues, it is important to have your device inspected right away.
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. Pipes in exterior walls, crawlspaces and unheated garages are the usual trouble spots when temperatures drop sharply. Regular testing and maintenance help lengthen its service life.
Water providers may send follow-up notices, charge fees or eventually suspend service. Scheduling early avoids these problems. We can often fit urgent tests in on short notice.
FGV Plumbing services all major types of backflow preventers, including Reduced Pressure Zone Assemblies, Double Check Valve Assemblies, Pressure Vacuum Breakers, and Atmospheric Vacuum Breakers. We work with popular brands like Watts, Wilkins, Febco, and Conbraco.
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 a must.
The lifespan of a backflow preventer usually ranges from 10 to 20 years, depending on the type, manufacturer, water quality, and maintenance. Regular testing and timely repairs can extend its life. However, certain components like rubber seals may need replacement sooner due to normal wear.
No, backflow preventer installation and major repairs should only be performed by a licensed and certified plumber. Improper installation or repair can lead to water contamination, which poses serious health risks and can result in steep fines from local authorities. Specialized tools and training are required.
