Backflow prevention is a legal requirement in most municipalities — and a direct safeguard for the drinking water your household relies on every day. UrbanValve Works installs, repairs, and tests certified backflow assemblies in Charlestown with same-day availability and code-compliant documentation.
Backflow occurs when water pressure in the supply line drops or reverses — allowing contaminated water from irrigation systems, pools, boilers, or chemical dispensers to flow backward into the clean water supply. In Charlestown, pressure fluctuations caused by main breaks, firefighting operations, or peak demand can trigger backflow events without warning.
Without a functioning backflow preventer, pesticides, fertilizers, pool chemicals, and even sewage can enter the potable water that comes out of your kitchen tap. Health departments in MA treat backflow contamination events as public health emergencies, and property owners can face liability if an uninspected or uninstalled preventer is discovered after an incident.
Aging backflow assemblies are a particular concern. The rubber seals and check valves inside a preventer degrade over time, and a device that passed inspection five years ago may fail silently without obvious signs. An assembly that leaks, drips, or fails the annual pressure differential test must be repaired or replaced promptly to maintain code compliance in Charlestown.
UrbanValve Works technicians are trained to identify the correct device type for your application — reduced pressure zone assemblies, pressure vacuum breakers, double-check valve assemblies — and to install them where municipal inspectors in MA require them: at the water meter, at irrigation connections, and at any cross-connection point with a potential contamination source.
We evaluate your water pressure, line size, and connection type to determine the correct backflow assembly classification required by MA plumbing code and your local water authority.
Our licensed plumbers install the approved device, ensuring proper orientation, clearances, and shutoff valves as required. All installations comply with the latest code adopted in Charlestown.
Every installation is tested on-site by our certified backflow tester using calibrated differential pressure gauges to confirm the assembly operates within specification before we leave.
We file the required test report with the Charlestown water authority and provide you with a copy for your records. You receive a reminder when your next annual test is due.

Backflow prevention requirements vary significantly between municipalities, and Charlestown has its own water authority specifications for approved device models, installation heights, and annual testing deadlines. UrbanValve Works has worked directly with local inspectors and is familiar with the exact documentation format the Charlestown water department accepts.
The water distribution system in Charlestown experiences the same pressure variability found throughout MA — seasonal demand spikes, infrastructure maintenance shutoffs, and occasional main breaks all create conditions that stress backflow assemblies more than manufacturers' ratings assume. We size and select devices with these local operating conditions in mind, not just minimum code compliance.
We also handle the annual testing requirement that many Charlestown property owners let lapse. Missing a testing deadline can result in a notice of violation from the water authority and a mandatory shutoff order in serious cases. Our reminder system keeps your assembly in compliance year after year without requiring you to track the deadlines yourself.
"Our irrigation system failed its annual backflow test and the water company gave us 30 days. UrbanValve Works replaced the assembly the next morning and filed the paperwork the same afternoon. Couldn't have been smoother."
— Homeowner in Charlestown"I had no idea my older home didn't have a backflow preventer on the boiler connection. The technician caught it during a routine visit, explained the risk clearly, and installed the right device that day."
