It is important to make sure your home’s plumbing system is properly vented. The purpose of venting a basement plumbing system is to ensure proper drainage of the water coming in from the main line and any other pipes going to other parts of the house. Without proper ventilation, air can become trapped inside of plumbing pipes and cause problems, such as a drain line backing up and potential flooding. Here are some of the positive benefits of venting your basement plumbing.

1. Prevents Negative Air Pressure

When a large volume of water pressure enters a basement plumbing system, it can create negative air pressure which can cause back-siphonage. This is when contaminated water is able to travel back up into a home’s plumbing system. Vents are able to block this from happening.

2. Creates a Safe Environment

Venting a basement plumbing system also helps to create a safe indoor environment, as it prevents any toxic gas building up in areas of the home. This could be caused from the drainage water’s decomposing substances.

3. Reduces Noisy Pipes

Opening up a vent for your basement plumbing system will also help to reduce the noise that pipes can make. Pipes such as the ones in a bathroom running water for a bath or shower will automatically become less noisy when air is allowed to escape.

4. Reduced Risk of Water Damage

When the air pressure in a plumbing system is too high, it can cause pipes to burst and overflow; it can also become submerged in stagnant standing water. When the pressure is regulated, a basement plumbing system is much less likely to experience serious water damage.

Ventilating a basement plumbing system can be beneficial, as it helps to prevent issues with back-siphonage, create a safe environment, reduce the noise made from running pipes and reduce the risk of water damage. It is a good idea to make sure when a basement is being built that the plumbing system is properly vented in order to avoid any problems in the future.
