Most manufacturers use modern plastic materials to make high-quality valves. They are simple assembly valves with a small mechanism on the top, and their design depends on capacity and the manufacturer. How Does Air Admittance Valves Look?Īir Admittance Valves come in different sizes, materials, and colors. It will stay closed as long as the pressure in the drainage pipes is positive. When the seal in the valve closes, it prevents bad odors from escaping the sewer system. As a result, the fresh air will come in and help to equalize the pressure.Īfter equalizing it, the sealing is automatically closed thanks to the gravity pulling it back to its position. If the lower atmospheric pressure appears in the drainage system, the seal in the valve will automatically open and lift. It is possible because these valves react to pressure in the drainage system. How Does Air Admittance Valves Work?Īir Admittance Valve (AAV) allows the air to enter the drain system and prevents bad smells from coming out at the same time. They will tell you if it is legal to install this system in the region where you live. If you are not sure what to do, you can always check with local plumbing authorities and associations. The plumbers install Air Admittance Valves regularly, and there are no legal actions against installing them so far. Several famous manufacturers make these systems on the American soil, and the majority of local hardware and plumbing shops sell them.
In the US, the legal issue of Air Admittance Valve is a bit of a grey area.
Atmospheric pressure goes through the valve and has the same effect as in the classical venting.Īctually, this system is not a rare solution in Europe and many other parts of the world. It is a simple mechanism that replaces classical venting pipe systems. In many situations, it is impossible to install standard venting for various reasons, and the installation of Air Admittance Valves can solve that problem. You may have heard that they are illegal and unreliable, but you shouldn’t believe every rumor. Instead of thinking about massive construction projects, you can use an Air Admittance Valve, well-known as a cheater vent.

How to Vent without a Ventĭon’t worry if you do not have a vent pipe in your house, or if it is blocked and you can’t fix it. Luckily, there are a few more elegant solutions. Since these pipes penetrate your roof, you will need to mend leaky roofs and ruined ceilings sooner or later.

Most houses have these pipes in the roof, far from windows and household ventilation. Therefore, venting the pipes is necessary and obligated by building laws. Moreover, you will not have problems with clogged drains and slow drainage of wastewater. As a result, there will be neither bad smell nor strange noises coming out of sewer pipes. When you flush the water in your toilet, the odor will go smoothly through the vent pipe, thanks to the process of equalizing the atmospheric pressure in the drain system. That open pipe, connected to the waste, sewer, and pipes, will supply air to the waste pipes. You need to implement one vertical vent pipe to the top of your roof, and it will vent the entire system. Since it shouldn’t be too low or too high, you need to find a way to allow the equalizing of the pressure in the pipes with atmospheric one.Īctually, it is not too hard to achieve that. If you have a closed sewage system, you will have a lot of problems with misbalanced pressure. That pressure needs to be in balance in waste pipes to allow the correct work of water supply and sewerage systems. The process is more complicated and in direct connection with plumbing and sewer pipes.Īs you know, atmospheric pressure affects everything on the planet, including our toilets. What is Venting?Įven though people usually believe that venting the American standard toilet is just quick ventilation regarding bad smells, it is not that simple. Therefore, it is a good idea to understand the venting system and why do we need it. You need to follow modern innovations in getting rid of awful odors. Nowadays, it is not enough to pay extra attention to excellent venting systems. Unfortunately, it is a regular part of the action happening in toilets, which makes proper venting an essential part of our homes. We use our toilets for flushing and disposing of our liquid and solid waste, but none of us like that awful smell.
