SEWER AND DRAINS
Your plumbing system is comprised of two parallel subsystems: the first brings fresh water into your house.
The second, which removes waste-water from your house, is the drainage system.
The latter in fact includes three components – drain, waste and vent – and is thus often referred to as the DWV system.
Your Drain System Structure
Drain lines collect water from the various fixtures; waste lines carry toilet wastes and vent pipes, which protrude from the roof, allow harmful sewer gases to evaporate, thereby also relieving pressure from the drain pipes and enabling waste to flow properly.
Originating at the various fixtures, drain and waste lines tilt downwards and are pulled down by gravity.
Their final destination is the main sewer line which, in turn, carries waste matter to a sewage facility or to a septic tank.
Shape and Size
Most drainpipes are made up of cast iron, plastic and, at times, of copper.
To reduce the chances of blockages and clogs, drainpipes are larger than water pipes, their diameter ranging between 4 and 10 cm.
Toilet drainpipes are usually 10 cm in size, shower drains are served by 5 cm pipes, whereas sinks and bathtub drains have 4-5 cm pipes.
Vents are not the only means by which hazardous gases are emitted from your house.
An additional device known as trap fills a similar function.
A trap is the curved section of the drainpipe, located next to each fixture.
Whenever a fixture is used, some of the water emanating from it flows through the trap into the drainpipe, but a sufficient amount of water stays within the trap, and in fact forms a seal which prevents sewer gases and objectionable odors from permeating your home.
Clogged Drains and Root Intrusion
Still, drain clogs do happen. To clear up a clog you can always begin by accessing the traps through their clean-out valves, and thereby remove such common obstructions as grease and hair.
All waste lines should include clean-out valves, through which your expert New York plumber can clean out the pipe. Indeed, if the clog persists, ask your plumber to use his drain cleaning equipment to solve the problem. Standard tools for clearing clogged drains include plungers, various types of augers such as plumber’s snakes and toilet augers, as well as sewer tapes.
If it is the drains outside your house that are clogged, it might be due to tree or bush root intrusion.
If roots are the case then the problem may be severe, and might end with changing to a PVC pipe.
Rooter services are provided by Domco plumbing to target effectively the reoccurring problem of root invasion.
