Frequently Asked Questions About Backflow Preventer in Hilton Head Island
Annual residential backflow testing usually 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.
No. Testing must be performed by a certified backflow tester using calibrated equipment. Water providers only accept reports from licensed testers.
Constant dripping from the relief valve, low water pressure and visible cracks are typical signs. Discolored water or a failed test notice also indicate a problem. Prompt repair keeps you in compliance.
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 crawlspaces, exterior walls and unheated garages are the ones most likely to burst during a South Carolina cold snap, since many homes were built with little insulation around them. Regular testing and maintenance help extend its service life.
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 usually used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code rules.
A standard test usually takes 20 to 45 minutes per assembly. Water is briefly shut off during testing. Repairs may add an hour or more.
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.
Yes. Parts carry the manufacturer warranty and our workmanship is guaranteed. Every repair is retested to verify it passes before we leave.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
