Fire Line Backflow Testing in Gorham
Fire sprinkler systems usually use double check or double check detector assemblies to keep stagnant water out of the public supply. These assemblies need regular testing, often coordinated with fire system inspections. We test and repair fire line assemblies and document the results. We can line up scheduling with your fire protection contractor.

Irrigation Backflow Preventer Installation in Gorham
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 Repair vs. Replacement Cost in Gorham, ME
Repairing a failed assembly with a rebuild kit is often the most affordable choice. Replacement makes sense when the body is cracked, parts are discontinued or the device is the wrong type for the hazard. We compare repair and replacement costs on the spot. You choose the option that fits your budget and compliance requirements.
Backflow Preventer Testing in Gorham
BKN Plumbing provides certified backflow preventer testing required by many Maine municipalities. We use calibrated equipment to check the device, making sure it properly prevents reverse flow. Our technicians are licensed to perform these annual tests and submit all required reports to your local water authority, helping you avoid fines and stay compliant. We test all common types, including RPZs, DCVAs, and PVBs, with accurate readings and careful checks.
Freeze and Heat Protection for Backflow Preventers in Gorham, 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.
