In most modern plumbing, a waste-water-venting system is actually part of an integrated system that allows outside air to access a home’s plumbing system in order to keep proper indoor air pressure so that the discharge of graywater and sewage can be maintained at a reasonable rate. The graywater and sewage are usually produced by fixtures such as sinks, toilets, and showers.
As water flows through the sewer pipe or sewer line, it collects and accumulates. These accumulations can be as small as a tiny puddle in the corner of the shower drain or as large as the solid refuse that accumulates behind the toilet bowl drain on every flush. Graywater and sewage are not only a major problem but also a health hazard if they accumulate in a building for several months. This makes it necessary to have a waste water venting system installed.
When this drainage venting system is in place, the entire drainage system is brought under pressure which helps to prevent the buildup of grease, dirt, grease and other materials in the drain pipe. When this type of venting system is installed, it allows the air from the venting unit to pass through the pipe and into the room where the drain is located. The outside air in the duct system then carries away the dirt and grease that might otherwise accumulate.
There are a number of plumbing drainage venting systems available on the market today, however many are not properly installed. It is therefore important to use a plumber that has experience installing drain vents in various types of plumbing. There are even some venting units that are designed with a built in trap that traps any excess air from escaping as the pipe is being vented.
Drain venting units are generally a simple solution to a problem and can often be purchased with no major alterations to the home’s plumbing. Plumbing drain vents can be connected to a separate outlet to vent to a faucet or other location in the house.
Before deciding to install drain vents, a plumber will advise you of any and all plumbing problems that could potentially be a result of the venting unit. The plumber will also provide you with a checklist to ensure that the venting is installed correctly and that the venting units are properly attached and connected to their respective outlets.Wayne Saman
