Reduced Pressure Zone Assembly Installation in Topsham, ME
RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested. We carry trusted brands like Watts, Febco, Wilkins and Apollo.
Pressure Vacuum Breaker (PVB) Installation in Topsham, ME
For low-hazard applications, such as lawn irrigation systems in Topsham, ME, a pressure vacuum breaker, or PVB, is a common and cost-effective backflow prevention device. PVBs protect against back-siphonage by letting air into the system when pressure drops. Our certified plumbers expertly install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also make sure of proper clearance and drainage.
Double Check Valve Assembly (DCVA) Installation in Topsham
The double check valve assembly, or DCVA, is a common backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Topsham, DCVAs are frequently installed on fire sprinkler systems or irrigation lines. Our certified plumbers carefully install these devices, making sure both check valves operate correctly and are properly sealed to prevent backpressure or back-siphonage into the main water supply.
Emergency Backflow Preventer Replacement in Topsham
While installations are typically planned, sometimes an existing backflow preventer fails suddenly, creating an urgent need for replacement in Topsham. A compromised backflow device can lead to immediate contamination risks or code violations. BKN Plumbing offers emergency replacement service to promptly assess the situation, remove the faulty unit and install a new, code-compliant backflow preventer, restoring your water safety as fast as possible.
Residential Backflow Preventer Installation in Topsham
For homeowners in Topsham, protecting your family's drinking water is paramount. We install many types of backflow preventers, often required for irrigation systems, fire suppression lines or properties with alternative water sources. Our plumbers will assess your home's plumbing layout to recommend the most suitable device, meeting local health department regulations and protecting your potable water supply. We handle everything from small residential devices to larger systems.
Commercial Backflow Preventer Installation in Topsham
Restaurants, salons, dental offices and light industrial buildings often need multiple backflow devices on soda machines, boilers, dishwashers and process water. We survey the building, identify each cross-connection and install containment and isolation assemblies as required. Work is scheduled after hours or on weekends when needed to avoid shutting down your business. You receive documentation for each device for your records and your water provider.

Irrigation Backflow Preventer Installation in Topsham
Landscape irrigation is the most common reason homeowners need a backflow device. Fertilizer, herbicides and stagnant water in sprinkler and drip lines can be siphoned into your drinking water if pressure drops. We install pressure vacuum breakers or double check assemblies based on local requirements and the layout of your system. Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.
