Freeze and Heat Protection for Backflow Preventers in Durham, NH

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

Most municipalities, including Durham, require backflow preventers to be tested once a year. This regular testing makes sure the device is working correctly and continues to protect your potable water supply from contamination, as required by local water authorities.
The lifespan of a backflow preventer usually ranges from 10 to 20 years, depending on the type, manufacturer, water quality, and maintenance. Regular testing and timely repairs can extend its life. However, certain components like rubber seals may need replacement sooner due to normal wear.
Signs of a failing backflow preventer include discolored water, strange odors from your tap, a sudden drop in water pressure, or visible leaks around the device itself. If you notice any of these, contact a professional plumber right away to assess the issue.
New installations and replacements often require a plumbing permit and an initial test. Requirements vary by city and water provider. We obtain permits and handle the initial test.
