Drain waste and vent piping are the two most important components in plumbing. These are the systems that take water away from your home. Let us examine how do they work.

Drain Waste-Vent System and Gravity

Earlier galvanized caste iron was used in the piping system, but now-a-days PVC piping is generally used. PVC piping is much better than the galvanized caste iron, as the later one clogs much easier. This distribution PVC piping system brings the water to the toilet bowl and the drain waste-vent system takes all the used water and waste away from the home to the sewer or septic system.

The functions of most sewer systems are based on gravity. That is the reason why everything goes down. In this process, the wastewater runs down the drain, enters the waste line, and finally leaves the bowl. Supply lines in the drainage system are fitted at forty or ninety degree angles. This drainage specification goes with the flow and helps the gravity of the sewer system to move the wastewater.

The Venting System

Venting system is a piping system and one of the most important components of drainage. The venting system consists of pipes. You must have noticed several pipes sticking up through the roofs of the houses in your neighborhood. These pipes are the venting system.

This system is also an essential requirement by the building code, as it prevents the water to draw out of the traps that are under sinks. Moreover, the other main function of this system is to allow gases to escape. It also helps wastewater to drain properly by relieving air pressure.

House Trap and Lateral Line

When the plumber ties the waste water pipes into the sewer line, he/she also installs house trap and lateral line. The main function of the house trap is to keep the waste and odors flowing out of the home, while the lateral line ties the house to the municipal sewer line.

This lateral line first goes into a sewer system down the street, and then it collects through a main distribution line, and finally goes to a sewer processing plant.

Air Admittance Vents

Air admittance vents are fitted under the sink. It helps sewer gases from coming out while drawing a bit of air in from under the sink. This way, these vents save money for you by reducing the amount of waste line vent stacks that you run. Moreover, they also help in reducing the possible number of penetrations through the roof.

Other Important Things

 - The sewage lines coming into the house must be higher than where they go to connect to the city sewer line. This is an essential requirement, as we know that the sewage moves by gravity.

 - There must be at least 2%-3% fall in your sewer system. However, it depends on the elevation of your home as well as the elevation of the city, which is the location of the connection.

 - The fall the drain waste-vent system that carries fluids through the sewage system must be at least 0.25 inch per foot.

 - There must be two-degree fall into the main line for the lateral.

Hence, here we see what are the components of a drain waste-vent system, and how do they work.

Basement bathroom plumbing work needs considerable skill, experience and care. It is advisable to hire the services of a plumbing contractor for carrying out basement bathroom plumbing work. The existing floor needs to be busted and in the process drainpipes may also get broken if adequate safety measures are not taken up.

Often, the concrete of the basement needs to be broken. Marks are made on the surface along some demarcations and the concrete is chipped away usually employing a jack hammer. The debris thus obtained has to be cleared and new plumbing pipes are well glued to the original setup. After completion the new setup has to be covered up with concrete.

Another approach to basement bathroom plumbing is installation of a plastic sump beneath the basement floor. A sewage ejector pump or lift pump is used to pump out the waste as the sump becomes full. The pumps have devices to grind solids. In case the pump fails the toilet will not be draining properly.

There may be some houses where the building drain lies below the basement level. So, no pump is needed. A plumber can help in this regard by providing various estimates of drain line locations and plumbing setup plans.

Again, there may be homes where the main drain lies at floor level. To help out in such cases you may build a false floor for the bathroom. Of course your ceiling needs to be high enough in such case. The false floor erection would ensure that the fixtures are higher than the sewer line. This will do away with the necessity of installing a sewage ejector pumping unit.

Normally, with only one button and drag the joints are all that is necessary. Sometimes new thread seal will be installed.

In a bonded joint, but the city is cut off and replaced by a new glue, because there is no possibility of a seal without breaking apart joints. In most cases, these types of repairs in the basement will be under the house. Sometimes leaks occur, this type of water heater and hot water pipes. This is due to water pressure and heat.

The hot and cold water left on the right side with cold water to the toilet. Normally, everyone knows, but if a plumber is lying on his back in a house, it is possible to confuse left and right.

The drain pipes in a house should have slope 1 / 4 inch every 10 feet of drain. If you bring a good point, it will back up or at least has the potential for such. These deficiencies are not usually caused by the installation of water supplies clothes hangers on the appropriate distance.

To test DWV systems, you need to make the leak in your sinks and bathtubs and running water nearby to see whether it contains water or not. If it does not leak, then open the drain and let the water drain in the hunt at the same time your toilet (s). Thus, the drainage pipes under the house will fill with water so that you can check for leaks and proper flow of drainage.
