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 standard test usually takes 20 to 45 minutes per assembly. Water is temporarily shut off during testing. Repairs may add an hour or more.
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.
Most municipalities, including Gainesville, require backflow preventers to be tested annually. 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.
HDF Plumbing stands behind our work with a full warranty on parts and labor for all backflow preventer services. The warranty period will be outlined in your service agreement, but generally, new installations come with a manufacturer's warranty on the device and our warranty on the installation.
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.
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. Specialized tools and training are required.
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 requirements.
