Backflow prevention devices ensure that contaminated water does not enter potable water systems. This can be an issue with older residential boilers and other heating/cooling systems, pumps controlling water drainage or distribution, lawn or garden irrigation, laundry sinks and pressurized washers.
My Favorite Plumber offers the following services to prevent backflow:
Backflow prevention options include an atmospheric vacuum breaker (AVB), double check valve and reduced pressure zone device (or RPZ valve).
Keeping a backflow device in good working order is essential to avoid contamination of drinking water. If you notice a problem or issues are revealed during an inspection, call My Favorite Plumber right away—we can fix all types of backflow devices and install a replacement if necessary.
Backflow prevention is not just a nice-to-have: it’s a must-have, both for health and to avoid violating the law. Backflow preventers are mandated in any situation where the reverse flow of polluted water could enter the “potable” (drinking) water system.

Many local ordinances require the use of backflow preventers. My Favorite Plumber can take care of any testing and certification requirements, performing yearly certification inspections and submitting paperwork to the water company.
Yearly certification helps ensure that no contaminated water enters your fresh supply from sources such as sprinkler systems or boilers. Call My Favorite Plumber if you are not sure how long it’s been since your devices were inspected.
