How to ventilating a toilet without a vent?

A good pipeline system will have a specific set of pipes, each of which connects to individual drain p-trap. These pipes also extend to the main pipe that sticks to the roof through the house.

This set up is not feasible for some homes, so it is necessary to find alternate ways to vent a toilet.

We use our toilets to flush our liquid and solid waste, but none of us like that bad smell. Unfortunately, it is a normal part of what happens in the bathroom, and proper ventilation becomes an important part of our home.

People generally believe that toilet ventilation is fast to remove bad smell, however, it is not so easy. The process is more complex and it has a direct relationship with the plumbing and sewer pipes.

Atmospheric pressure affects our toilets and the pressure in the waste pipes needs to be balanced to allow for the proper working of the water supply and drainage system.

When the toilet water is flushed, the smell is passed to the vent pipe and equalize the atmospheric pressure of the drainage system. As a result, there will be no weird smell or noise from the sewer.

Let’s see how to vent a toilet without a vent:

If your house does not have a vent pipe, or it is blocked and you cannot fix it. Instead of thinking about large-scale construction projects, you can use an air admittance valve, also known as a ‘Cheat Vent’.

Some people say that this is illegal and unreliable, but you should not believe these gossips. In many cases, it is impossible to install standard ventilation for a variety of reasons.

The installation of Air Admittance Valves solves that problem and this is a simple procedure.

It can be done by replacing classical venting pipe systems. Atmospheric pressure passes through the valve and affects the same as the classical venting.

Plumbers regularly install Air Admittance Valves and so far, no legal action has been taken against their installation. You can always check with your local plumbing authorities and associations and they will tell you if it is legal to install in your region.

If local building rules allow the use of Air Admittance Valves, you should choose a quality product. There are many models available in the market, but a good valve should be able to prevent sewer gas from leaking back into your home and offer the least noise when water flows through it.

If there is low atmospheric pressure in the drain system, the valve seal will open and lift automatically. As a result, fresh air enters and helps balance the pressure.

After equalizing, the seal closes automatically and returns it to its position due to gravity. When the valve seal closes, it prevents the bad smell from escaping from the sewer system. It will remain closed as long as the pressure in the drain pipes is present.

If you have an apartment, you don’t need much space and you can place it under the sink in your kitchen or bathroom. The size of the site should be matched to the dimensions of the valve and the tee sanitary waste pipe. It is enough to determine the valve throughput and the number of units required.

If you have a house, you can install the system anywhere, such as in the attic above the insulation or in the basement connected to the sewer. If there is a cavity in the wall, you can install the Air Admittance Valve there. In this case, you will need to purchase a model that has recesses and grills to allow air in and out.

Many domestic and foreign manufacturers make these systems and they vary in design, capacity, material, and temperature where they can operate. You need to choose the most reliable brand and the model with the longest warranty.
