Causes if Backflow in Plumbing

August 18, 2022

What is plumbing backflow? Plumbing backflow is when water flows backward through your plumbing system. The most common cause is a sudden change in water pressure. This can cause contaminated water to flow back into your home or business, leading to serious health problems. What are the main causes of backflow in plumbing?

1. Backward Pressure

Every other water system is designed to work under pressure. Backflow can occur when there is a sudden change in water pressure. A drop in water pressure can be caused by several things, including a pump failure, a power outage, or even a broken water main. When water pressure drops, it can cause dirty water to flow back into your home through the plumbing system. Therefore, it’s important to have a backflow preventer installed in your home or business to protect against this type of contamination.

2. Cross Connection

A cross connection is another common cause of backflow in plumbing. This occurs when there is a connection between your potable water supply and a contaminated source. Cross connection can happen if you have a garden hose connected to your water supply or a swimming pool or hot tub that is not properly isolated. A sudden change in water pressure can cause dirty water to flow back into your home through these connections. Again, a backflow preventer can protect against this type of contamination.

3. Improperly Installed Fixtures

If fixtures are not installed properly, they can cause backflow in plumbing. This is most common with shower heads since they are often installed incorrectly. If the shower head is not installed at the correct angle, it can create a siphoning effect that can draw dirty water back into your home. Therefore, it’s important to ensure that all fixtures are installed properly to avoid contamination.

How To Deal With Backflow in Your Plumbing

As you already know, backflow in plumbing can be a serious problem. If you suspect your home or business has backflow, it’s important to take action immediately. The first step is to contact a professional plumber who can assess the situation and determine the best course of action.

They may recommend a backflow preventer be installed to protect against future contamination. In some cases, they may also recommend flushing the entire plumbing system to remove any contaminants that may have already entered. Second, you should also contact your local water supplier. They can test the water to see if it has been contaminated and take the necessary steps to purify it.

You also need to ensure that you take the necessary steps to avoid backflow in the future. This includes installing a backflow preventer and ensuring that all fixtures are installed properly. You should also avoid using garden hoses and other connections that could create a cross-connection. By taking these steps, you can protect yourself and your family from the dangers of backflow contamination.

Conclusion

The issue of plumbing backflow is often overlooked until it’s too late. Backflow can lead to serious health problems, so it’s important to be aware of the causes and take steps to prevent it. The most common cause of backflow is a sudden change in water pressure, but cross-connections or improperly installed fixtures can also cause it.
