Whether you are installing a new irrigation system, fire suppression system, or need to replace an outdated device, BWM Plumbing handles professional backflow preventer installations. We assess your property's needs and local plumbing codes to recommend the correct type and size of backflow preventer.

Annual Backflow Testing in Somerville

Test results are recorded on the provider's form and submitted for you. If the assembly passes, you are done until next year.
Irrigation Backflow Preventer Installation in Somerville
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.

Protecting the assembly helps it pass testing and last for years.
