The Telltale Signs of Poorly Vented Plumbing Drain lines

Are you aware of the signs of poorly vented plumbing drain lines? If you are, then you should take note of them because they might cause serious problems later.

The plumbing system is one of the most important parts of your home. It helps us get water from the source to our sinks and toilets. However, it also has its share of issues. One of these is the drainage pipes. They are responsible for carrying away waste water from the sink or toilet. This is why it is very important to ensure that they are properly installed and maintained.

There are some common signs that indicate that your plumbing drain line is leaking. These include the presence of water stains around the area, slow draining of the tub or shower, and foul odors emanating from the drains. If you notice any of these, then you should immediately contact a professional plumber.

What Happens if a Drain is not Vented Properly?

If you have an unvented drain, then there will be no ventilation in the drain pipe. As a result, the water inside the drain pipe will become stagnant and start collecting. Over time, this can lead to several problems.

The first problem is mold growth. Mold grows when there is moisture present in the air. When there is no proper ventilation in the drain pipe, then the moisture stays inside the pipe and starts growing mold. This can result in the formation of black spots on walls and ceilings.

Another problem with having an unvented drain is that it could increase the chances of flooding. There is nothing wrong with having a few puddles here and there. But when the amount of water increases, then it becomes a major issue. This is especially true if you live in a flood prone area.

How Can You Prevent Unvented Drains From Becoming Problems?

You need to make sure that your drainpipe does not collect too much water. To do so, you need to remember to turn off the faucet whenever you are done using it. Also, make sure that you flush all the toilets before leaving the house.

You must also make sure that you keep your drains clean. This means that you need to remove all food particles and other debris from the drain. In addition, you should regularly check for blockages. Any buildup of debris can prevent the flow of water through the drain.

Also, make sure that you use only approved products for cleaning your drains. The chemicals used by non-approved companies may damage the lining of your pipes.

How Do You Fix Leaks in Your Plumbing System?

When you find out that your plumbing system is leaking, then you need to fix it as soon as possible. The longer you wait, the more likely it is that the leak will worsen. Therefore, you need to act fast to avoid further damage.

To repair leaks, you need to identify where the leak is coming from. Once you know which part of the system is leaking, then it is easier to pinpoint the cause. For example, if you see water dripping from the ceiling, then you know that the leak is coming from the roof. Similarly, if you hear gurgling sounds coming from the bathroom, then you know that it is coming from the pipes under the floor.

Signs of Poorly Vented Plumbing Drains Lines

There are some common signs that show that your plumbing drain line has a leak. Some of these signs include:

1. Slow Drains

If your drains are slow, then there is something wrong with them. One of the most common causes of slow drains is the presence of clogs. Clogs occur because of the build up of hair or other foreign materials. These clogs restrict the flow of water through your drains.

2. Water Damage

One of the biggest problems with poorly vented plumbing drains is that they can lead to water damage. If your drains are not properly ventilated, then this leads to condensation.

Condensation occurs when the temperature of the air drops below the dew point. As such, if you leave your home without turning off the water supply, then you risk getting water damage.

3. Weak Flushing Toilets

Another sign that your plumbing drain line is leaking is weak flushing toilets. When your toilet is flushed, then it sends waste down into the sewer pipe. However, if your toilet is not working well, then it is unlikely that you will be able to get rid of all the waste.

4. Sewer Odors

Sewer odors are another indication that your plumbing drain line needs fixing. If your drains smell like sewage, then you need to contact a plumber immediately.

6. Pipes Bursting

Pipes bursting is another sign that your plumbing drain lines are leaking. This happens when the pressure inside the pipes increases and they burst open.
