A stormwater backflow valve is a device that prevents raw sewage from entering your home. These devices are often used in homes where the sewer is located in the basement. They are installed by a licensed plumber. In some cases, these valves are required by law.
These devices can be automatic or manual, but they are generally located near the drain piping in your home. They are a critical part of any stormwater system and can prevent flooding. They should be checked regularly. Usually, they have easy-to-remove covers. They are also available in different designs and sizes. It is important to install the right one.
The first step in installing a backwater valve is to locate the valve access panel. A plumber can inspect your drainpipe and make recommendations. Depending on your local codes, you may have to apply for a permit. In addition, you may have to dig a portion of the main sewage line. It is a good idea to get at least three quotes from qualified plumbers. You can ask to see references from similar projects.
The next step is to design a system that will prevent any backups. Typically, this is done by separating flows into those that do not need protection. For example, if you have a low-level fixture in the basement, you should connect that fixture to the floor drain instead of to the sanitary sewer.
The second step is to install a valve that will keep your sewage from getting into your home. The stormwater backflow valve most common type is a manual backwater valve. These are typically located six inches under the water. They are easy to open and close. You can remove the lid for cleaning. If you use an automatic backwater valve, you should install it at the end of the pipe. You should choose a device that is designed for a low slope. This will ensure that the sewage will flow downhill.
In addition to preventing sewage from being pumped into your home, these valves also help protect your family. Whenever you are cleaning, wear rubber gloves. This will help protect your hands and prevent the spread of bacteria.
In the event that a backwater valve becomes clogged with debris, you should call a professional to clean it. You will also want to take care to remove the cover. This will also help to maintain the valve’s performance.
The third step is to determine which type of valve is best for your situation. Some types are specifically designed for stormwater. These include ball check valves, pressure vacuum check valves, and floatable ball check valves. They come in varying sizes and are rated for up to seven years of operation. They are designed to prevent debris from clogging the valve’s seat.
If you are considering a backwater valve, it is best to consult a licensed master plumber. You should also check with the municipal government to see if your home insurance policy covers backups. The last thing you want is to get a bill for repairs because your plumbing was not up to code.
