Simple Basics About Plumbing & Drainage

Your home plumbing system consists of 2 subsystems, fresh water and drainage, which work together, moving fresh potable water in and carrying dirty waste water out. Here are a few basic facts that you should know about plumbing drainage systems to understand plumbing problems before calling a professional plumber.

A water drainage system in residential properties usually works on the principal of gravity, with the drains being sloped and constructed along a plan to carry waste water out using gravitational pull. Although this sounds simple enough on the surface of it, it is actually far more complicated than it sounds and it is important to hire a professional plumbing service with adequately trained plumbers to lay your pipes both for inlet supply of water as well as for draining waste water. Public drainage systems further take sewage to a municipal sewage treatment facility or you may have a septic tank installed. In the absence of a professional plumber involved in the planning stage it is most likely that you will have drainage and plumbing issues that lead to water damage and costly repairs in the future.

A drainage system consists of a system of traps, vents and clean out valves. Traps are present and clearly visible under every bathroom sink! A drain trap is the "S"
 shaped portion under the sink. A drainage trap lets out the water that you use n the sink while still maintaining a level of water in the S-shaped portion to effectively block out sewer gas that will make your bathroom stink. Plumbers will install traps and plugs under wash basins, in pipes and even under bathtubs. Clean out valves are placed along sewage lines to assist in the cleaning out of blockages easily.

The last part of the drainage plumbing system is the vent. A vent lets air in and out of the drainage plumbing pipes, letting water flow out smoothly. Drain vents are usually found sticking out of the roof of your home or in apartment blocks in shafts.
