We make sure your family's drinking water stays clean and your home meets all local water safety rules.
Irrigation Backflow Preventer Installation in Topsham
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 proper height. Insulated covers or enclosures help protect it from weather damage and theft.
Reduced Pressure Zone Assembly Service in Topsham, ME
RPZ assemblies protect against high-hazard cross-connections at restaurants, medical offices, car washes and buildings with chemical feed systems. They have two check valves and a relief port that discharges water if a check fails. We install, test and rebuild RPZ units from Watts, Febco, Wilkins and Apollo. Proper drainage is designed for the relief port discharge.
Backflow Preventer Repair and Rebuild in Topsham, ME
Common failures include worn check valve rubbers, debris stuck under seats and relief valves that drip constantly. We isolate the assembly, disassemble it and replace the worn parts with the manufacturer rebuild kit. Then we retest to verify it passes. Rebuilding usually costs much less than replacing the entire assembly.

Whether you are installing an irrigation system, a fire suppression line, or require a new backflow preventer for your domestic water supply, BKN Plumbing provides professional installation services. We assess your property's needs and local Topsham plumbing codes to recommend the most appropriate device type and size. Proper installation is key to lasting protection against contamination.
Backflow Preventer Testing in Topsham
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 necessary 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 Topsham, ME
Above-ground backflow assemblies are exposed to summer sun and winter cold. Frost reaches deep into the ground, so water and sewer lines in Maine must be buried safely below the frost line. 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 for years.

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.
