Frequently Asked Questions About Backflow Preventer in Hockessin
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 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. Hard freezes are usually short here, but a single cold night can still split an outdoor faucet left connected to a hose. Regular testing and maintenance help extend its service life.
No, backflow preventer testing and repair must be performed by a licensed and certified backflow prevention assembly tester. Delaware enforces a statewide plumbing code based on the International Plumbing Code, and plumbers must hold a state-issued license. Improper handling can lead to serious water contamination.
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 compliant.
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 due date.
Backflow preventers stop contaminated water from flowing backward into the public supply during pressure drops. Irrigation, fire lines and commercial equipment are common sources of contamination. Water providers require them to protect public health.
New installations and replacements often require a plumbing permit and an initial test. Requirements vary by city and water provider. We obtain permits and handle the initial test.
Signs of a failing backflow preventer include discolored water, strange odors from your tap, a noticeable 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.
