Venting Plumbing the Right Way

Ventilation is a very important part of your house’s plumbing system. Each fixture, from the toilet to the shower, has to be attached to vent pipes. The pressure of air drawn from the outside and into vent pipes helps push used water or waste down drain pipes. Not only that, as vent pipes lead to the roof, they expel all sorts of bad odours and harmful gases from a property.

Highlighted below are the things you need to do to vent plumbing property. Before everything else, make sure to be familiar with the plumbing of your property and the plumbing and building codes of your area to avoid running into problems with the authorities.

The Basics
1. Choose the right pipe material for the vent system. When choosing pipe materials, make sure that it fits your budget and needs, and is compatible with existing pipes. Many plumbing vent systems make use of small pipes that measure less than 10 inches in diameter; thus, you can use plastic pipes (ABS or PVC pipes). However, there are cases when steel, iron, or copper pipes are best. Regardless, choose strong, durable, flexible, and easy-to-join (relatively) pipes.

2. Consider pipe size constraints. Bigger pipes offer you more freedom when it comes to the number of fixtures and the distance between them.

3. Acquire the fittings and materials you need to join and support the plumbing vent system.

Dry Venting
A dry vent system is a simple system wherein every fixture has a vent pipe. It is easy to implement as you need not worry about placing different fixtures near each other or using large pipes. A disadvantage of this system, however, is having so many vent pipes sticking out of your roof, but if you can work around this, then you can go ahead and make a dry vent system.

1. Make a dry vent by having a vent pipe attached to the drain pipe of a fixture. Make sure to position it within two feet of that fixture.

2. Extend the pipe out of the building, following building regulations. Usually, the vent pipe needs to extend six inches from the roof or 12 inches from vertical walls.

3. Repeat the two steps above with other fixtures that you are installing.

Creating a vent system for your plumbing fixtures is a challenging task. In fact, you should just leave this task to plumbing professionals if you lack even one of the materials, fittings, or equipment needed.
