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.

Freeze and Heat Protection for Backflow Preventers in Kennebunk, ME
Above-ground backflow assemblies are exposed to summer sun and winter cold. Seasonal camps and cottages are usually winterized each fall, and many year-round homes use heat tape and pipe insulation. 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.

Frequently Asked Questions About Backflow Preventer in Kennebunk
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.
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.
Most municipalities and water utilities require backflow preventers to be tested every year. This confirms the device is working correctly to protect the public water supply from contamination. We can help you schedule these regular inspections.
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.
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.
Most municipalities, including Kennebunk, 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.
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 steep fines from local authorities. Special tools and training are required.
Water providers may send follow-up notices, charge fees or eventually suspend service. Scheduling early avoids these problems. We can often fit urgent tests in on short notice.

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.
