An unfortunate symptom of home plumbing systems is the unwanted reverse flow of water - also known as backflow. When this occurs, it can bring a hoard of contaminants into your home’s water supply, causing unsavory water, illness and even death. In a given year, there are more than 10,000 cases of blackflow contamination. In parts of Minnesota, especially in the heavier populated areas such as the Twin Cities, the hazards are even greater.
The Minnesota Department of Health has recognized the dangers of backflow contamination by taking and installing protective measures at high-hazard cross connections. While this protects municipal water supplies, homeowners are still encouraged to take precautions to help prevent backflow contamination.
Below are some top ways to do so from the pros at Minneapolis Saint Paul Plumbing, Heating & Air:
Reduce Pressure Zone Device (RPZD): Even at the state level, reduce pressure zone devices are installed throughout Minnesota to help reduce backflow. Consisting of two independent check valves (valves that allow only one flow direction), RPZDs are installed in series with a pressure chamber in between for monitoring. As long as sufficient water pressure is maintained, the potable water supply into a Twin Cities home should be protected. Because of state regulation though, these systems need to be installed by a professional plumber and tested regularly to ensure proper usage and compliance with Minnesota plumbing code.
Plumbing Inspection: Other sources of backflow contamination can come from sewer, drain and water lines around your home. While a basic, visual inspection can determine major issues, for true security it’s recommended to conduct advanced video inspections of your plumbing system. Utilizing camera systems that enter your sewer line to find hidden issues, a video inspection can determine sources of contamination you would have never known about. This eliminates guess work in troubleshooting and can get your home back to health as soon as possible.
Sewer and Drain Cleaning: The simple fact that your sewer lines and plumbing drains have a very dirty job to undertake should be proof enough of how important backflow prevention is. One simple measure to reduce risk is to have a professional clean, inspect and repair any part of your home’s sewer and drain system. If a drain or sewer line is clogged or slow moving, the chances of water moving backward is increased, so using advanced tools and environmentally safe and effective drain cleaners can help keep your home safe.
Backflow prevention is very important for the overall wellbeing of your Twin Cities home and family. In order to maintain all the responsible systems, it’s best to work with a trusted professional plumber.
