Reduced Pressure Zone Assembly Service in Highlands Ranch, CO
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 designed for the relief port discharge.

Irrigation Backflow Preventer Installation in Highlands Ranch
Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the required height. Insulated covers or enclosures help protect it from weather damage and theft.
Backflow Preventer Cost & Value in Highlands Ranch, CO
The cost of backflow preventer services in Highlands Ranch, CO varies depending on the type of service, such as testing, repair, or installation, and the device involved. While there is an upfront investment, a working backflow preventer provides important protection for your health and avoids potential fines or costly contamination cleanup. We offer clear pricing and detailed estimates before any work begins.
Annual Backflow Testing in Highlands Ranch
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 done until next year.
Commercial Backflow Compliance in Highlands Ranch
Commercial properties may have several assemblies on domestic water, irrigation, fire lines and equipment. We track test dates, schedule them together and submit all reports. Property managers receive a summary of every device and its status. This keeps you ahead of notices and avoids unexpected shutoffs.
Commercial Backflow Services in Highlands Ranch, CO
Businesses in Highlands Ranch often have more complex backflow prevention requirements due to higher water usage and diverse plumbing systems. GFR Plumbing provides full-service commercial backflow services, including large-scale testing, repair, and installation for multi-unit properties, industrial facilities, and restaurants. We understand the demands of commercial operations and work quickly to minimize disruption, keeping your business compliant and your water supply safe.
Freeze and Heat Protection for Backflow Preventers in Highlands Ranch, CO
Above-ground backflow assemblies are exposed to summer sun and winter cold. Hard freezes are a normal part of winter in Colorado, and pipes in exterior walls, crawlspaces, and garages are particularly vulnerable. 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 longer.

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 significant fines from local authorities. Special tools and training are required.
Most water providers require testing at least once per year. Some require testing after installation, repair or relocation as well. Your provider's notice will list the deadline.
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.
An RPZ, or Reduced Pressure Zone assembly, offers the highest level of protection, suitable for high-hazard cross-connections. A DCVA, or Double Check Valve Assembly, provides moderate protection and is typically used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code rules.
Signs of a failing backflow preventer include discolored water, strange odors from your tap, a sudden drop in water pressure, or visible leaks around the device itself. If you notice any of these, contact a professional plumber right away to assess the issue.
