As a homeowner, one of the most important things you need to keep in mind is backflow prevention. Backflow prevention is essential for keeping your drinking water safe from contamination, and it can also help you save money on your water bills. In this article, we'll be taking a look at some tips and tricks for making sure your home is properly protected from backflow. So read on to find out more! What is Backflow Prevention? Backflow prevention is a system used to protect potable water supplies from contamination or pollution. Backflow preventers are devices that allow water to flow in one direction only, preventing contaminated water from flowing back into the potable water supply. There are several different types of backflow preventers, including air gaps, double check valves, and pressure vacuum breakers. Air gaps are the most common type of backflow preventer. An air gap is a physical separation between the potable water supply and a possible source of contamination. Air gaps can be created by installing a shut-off valve in the piping between the two sources, or by placing the fixture (such as a sink) that uses the potable water supply further away from the possible source of contamination. Double check valves are another type of backflow preventer. Double check valves have two independent check valves that open and close in sequence. Water can flow through the double check valve in only one direction, preventing contaminated water from flowing back into the potable water supply. Double check valves must be installed by a qualified plumber. Pressure vacuum breakers (PVBs) are another type of backflow preventer. PVBs have a spring-loaded check valve that opens when water flows through it in the correct direction (toward the fixture), and closes when water tries to flow through it in the wrong direction (back toward the potable water supply). PVBs also have an air vent that allows Benefits of Backflow Prevention One of the most important things a homeowner can do to protect their drinking water is to install a backflow prevention device. Backflow devices prevent contaminated water from flowing back into the potable water supply. They are required by law in many states and municipalities, and are typically installed by licensed plumbers. There are many benefits to having a backflow prevention device installed in your home. Perhaps the most important benefit is that it protects your family from drinking contaminated water. Contaminated water can contain harmful bacteria and viruses that can cause serious illnesses. In some cases, contaminated water can even be fatal. Backflow prevention devices provide a physical barrier between your potable water supply and any potential sources of contamination. Another benefit of backflow prevention devices is that they help protect your home’s plumbing system from damage. When water flows backwards through your pipes, it can cause significant damage to your plumbing system. This damage can be expensive to repair, and may even require you to replace your entire plumbing system. Backflow preventers help protect your plumbing system by stopping the flow of water backwards through your pipes. Finally, backflow prevention devices can save you money on your water bill. When water flows backwards through your pipes, it can waste a lot of water. This wasted water translates into higher water bills for you as the homeowner. By preventing backflow, you can save money on your monthly water bill. Signs of a Potential Backflow Problem If you believe you may have a backflow issue, there are several signs to look out for. Water pressure that fluctuates or is suddenly much weaker than usual can indicate a backflow problem. If your water has an odd taste or smell, this could also be a sign that contaminated water is flowing back into your home. Or, if your water appears dirty or discolored, this could be an indication of backflow. If you notice any of these signs, it's important to take action right away and contact a professional plumber to come and take a look. They will be able to assess the situation and determine whether or not you have a backflow issue. If you do have a problem, they will be able to install a backflow prevention device to ensure that your water stays safe and clean. Tips for Preventing Backflow Issues Backflow is the term used to describe water flowing in the wrong direction. In a home plumbing system, this can happen when there is a change in water pressure. This can be caused by a variety of things, including a sudden drop in water pressure from the city supply or a clog in your plumbing. Backflow can also occur when there is an interruption in your power supply.
