No, backflow preventer installation and major repairs should only be performed by a licensed and certified plumber. Improper installation or repair can lead to water contamination, which poses serious health risks and can result in steep fines from local authorities. Special tools and training are required.
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 immediately to assess the issue.
BKN Plumbing stands behind our work with a comprehensive warranty on all backflow preventer repairs and installations. We use quality parts and hold our workmanship to high standards. Warranty details will be provided with your service agreement.
Backflow prevention is crucial because of changing water pressures, main breaks and fire flow that can drop pressure suddenly, and the potential for cross-connections from irrigation systems or industrial processes. These factors increase the risk of contaminated water entering the public supply, making a working backflow preventer a must.
A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan. Seasonal camps and cottages are usually drained and winterized each fall, and many year-round homes use heat tape and pipe insulation. Regular testing and maintenance help lengthen its service life.
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.
Most municipalities and water utilities require backflow preventers to be tested annually. This confirms the device is working correctly to protect the public water supply from contamination. We can help you schedule these regular inspections.
