Reduced Pressure Zone Assembly Service in Ann Arbor, MI
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.

Freeze and Heat Protection for Backflow Preventers in Ann Arbor, MI
Above-ground backflow assemblies are exposed to summer sun and winter cold. Pipes in exterior walls, crawlspaces, garages and poorly insulated additions are the most common places for a freeze to cause a break. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last for years.

Frequently Asked Questions About Backflow Preventer in Ann Arbor
Backflow preventer testing in Ann Arbor, MI usually costs between $75 and $150. This fee covers the technician's visit, the test itself, and the submission of required reports to your local water authority. Complex commercial systems or multiple devices may incur higher costs.
Most municipalities, including Ann Arbor, require backflow preventers to be tested once a year. This regular testing makes sure the device is working correctly and continues to protect your potable water supply from contamination, as required by local water authorities.
Backflow preventers stop contaminated water from flowing backward into the public supply during pressure drops. Irrigation, fire lines and commercial equipment are frequent sources of contamination. Water providers require them to protect public health.
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, garages and unheated additions are the most common places for a freeze to cause a break. Regular testing and maintenance help lengthen its service life.
Constant dripping from the relief valve, low water pressure and visible cracks are common signs. Discolored water or a failed test notice also indicate a problem. Prompt repair keeps you in compliance.
CHV Plumbing stands behind our work with a comprehensive warranty on all backflow preventer repairs and installations. We use quality parts and hold our workmanship to the highest standards. Warranty details will be provided with your service agreement.
New installations and replacements often require a plumbing permit and an initial test. Requirements vary by city and water provider. We pull permits and handle the initial test.
We service all major brands of backflow preventers, including Watts, Wilkins, Febco, Conbraco and Apollo, and Zurn. Our technicians are trained and equipped to handle various models and types, so your device receives expert attention and the right parts for repair.
