Backflow: Professional Plumber Advice | Las Vegas, NV

If you’ve ever experienced backflow in your plumbing, you know how frustrating it can be. Backflow is the unwanted reversal of flow in your plumbing system, and it can cause all sorts of problems, from water contamination to flooding. This article will explain some of the most common causes of backflow in plumbing and advice from a plumber so you can be better prepared to prevent it from happening in your home.

Defective Backflow Prevention Devices

One of the best ways to prevent backflow is to install backflow prevention devices, also known as cross-connection control devices. By using these devices, you can be sure that unclean water will not mix with your clean water. However, if they are not installed correctly or damaged, they can cause backflow. That’s why it’s so important to have a professional install and maintain your backflow prevention devices. If you have a backflow preventer installed in your home, it is important to have it regularly inspected by a plumber to ensure that it is functioning properly.

Improperly Installed Check Valves

Check valves are an important part of any plumbing system and play a vital role in preventing backflow. Unfortunately, if they are not installed properly, check valves can be a source of backflow problems. In most cases, backflow occurs when water is forced back into the piping system due to a change in pressure. This can happen if there is a sudden drop in water pressure or the system is not vented properly. Check valves are designed to prevent this by allowing water to flow in one direction only. However, if installed upside down or backward, they can cause backflow. As a result, it is important to ensure that check valves are installed correctly to avoid problems.


Flooding is one of the most common causes of backflow because it puts too much pressure on your drains and allows water to flow in the wrong direction. When your home is flooded, the water level in your sewer line can rise above the level of your drains, forcing sewage and other contaminated water back into your home. In addition, flooding can damage or destroy backflow prevention devices, making it even easier for contaminated water to enter your home.

To avoid problems with backflow due to flooding, it is important to have a professional plumber install strong backflow prevention devices in your home. These devices can help prevent water from flowing back into your house during a flood. It’s also critical to keep your drains clean and free of debris so that water may flow away from your property.

If you live in an area prone to flooding, it is also a good idea to have a backup plan in case your primary backflow prevention devices fail. This may include having a pump or generator on hand to keep your drains clear and prevent water from flowing back into your home.

Blocked Vents

Another common cause of backflow in plumbing systems is blocked vents. Vents are installed in plumbing systems to allow air to enter and equalize pressure. When vents become blocked, air can no longer enter the system, and this can cause water to be forced back through vents and into homes or businesses. In addition to causing backflow, blocked vents can lead to various other problems, including slow drains, gurgling toilets, and sewage odors. As a result, it is very important to ensure that vents are clear and unobstructed at all times. The best way to do this is to have them regularly inspected by a qualified plumber.

Clogged Drains

When drains are clogged, they cannot release pressure properly. This can cause backflow because the clog creates a blockage that traps water in the pipes. As a result, the water level in the pipes can rise and eventually force water back through vents and into your home or business. Clogged drains are often caused by grease, hair, soap scum, and other debris that build up over time. To prevent backflow from clogged drains, it is important to keep them clear and debris-free. This can be done by regularly cleaning your drains with a plunger or drain snake. If you have a clogged drain causing backflow, have it repaired as soon as possible by a qualified plumber.

Improperly Sized Pipes

In some cases, backflow can be caused by improperly sized pipes. If the pipes in your plumbing system are too small, they may not be able to handle the volume of water that flows through them. As a result, water can back up into your home or business. In addition, if the pipes are too small, they may not be able to ventilate the system, which can also cause backflow properly.

If you suspect that your pipes are too small, it is important to have them inspected by a qualified plumber. They will be able to determine if the pipes need to be replaced or if they can be enlarged.

Keep Your Plumbing Safe From Backflow

Backflow is a serious problem that can contaminate your water supply and lead to serious health hazards. It is important to be aware of the causes of backflow so that you can take steps to prevent it from happening in your home or business. If you suspect a backflow problem, you should contact a professional plumber in Las Vegas, NV, immediately so that they can diagnose and repair the problem before it gets worse.
