Toilets need to be properly vented to ensure that it functions properly all the time. Poor ventilation and/or clogging can cause problems with flushing, bad smells emitted, and other unpleasant things you might experience when you’re inside the restroom.

Homeowners can easily tell whether the problem with their plumbing is drainage ventilation. They can see bubbling in the water in the toilet which is a sign of trapped air. Water levels changing in your toilet can also tell you that there is a problem.

This problem can also be seen when you use a toilet plug regularly and the flushing problem keeps recurring. Water in your toilet that slowly goes down is also a ventilation problem when you ask a plumber.

In construction, vent pipes are now a requirement so that the air doesn’t get trapped inside them while also moving waste efficiently through the drainage. Even though pipes are hidden, here are some expert tips to make sure you know whether you have a ventilation problem or not.

Under the Sink

Vent pipes connect the drain and sink connection found on the wall under your sink. You can find this spot if you trace the pipe that runs down the drain to the wall. Check whether there is a vented pipe that connects the pipes in that plumbing section.
Prying the hole with a knife where it passes through will allow you to check to see the vented pipe. If it’s there then, you know your plumbing is ventilated. Usually, a single vent pipe for a bathroom is good enough to make it function well.

Attic Vented Pipes

Pipe connections that run through the attic will be a good indicator if whether your bathroom has vented pipes. It connects that drain pipe and the bathroom piping so that it allows air to escape in the attic to the roof.
Venting methods like these are usually done for bathroom that are far away from the main ventilation section of a house. Plumbing fixtures will dictate how many of these types of vented pipes can be found in your home.

Roof Vents

Pipe vents on the roof can be checked by two people. Locate the vent pipe under the roof that runs from the bathroom. Have a partner stay there while you flush the toilet downstairs. The sound of running water will indicate that the pipes are not clogged.

This can be done all throughout your house where your vent pipes are in the roof. It can be the sink, the drains, or other bathrooms. It will help you determine whether your ventilation problem comes from so you can address it.

Vented Pipe Functions

These types of vented pipes function to equalize the pressure on your drainage system. Clogged or uneven water levels show that air is trapped within the pipes and it needs to get out through the ventilation.
Gurgling water can be heard through the pipes when you try to flush your toilet. Don’t hesitate to call your plumber if you’re seeing these signs on your drainage pipes. Professional plumbers will know how to address this problem with the right solution.
