Whenever you decide to build a new house, the first and foremost thing that should not be neglected is the complete plumbing system. There is no point of having a beautifully decorated house if your washroom pipes are not functioning properly or your sink pipes in the kitchen are completely clogged or maybe some pipe is leaking which is dropping water from the ceiling.Also, not to forget that a good plumbing system can actually protect the community from many water borne diseases. It can keep the surrounding and inside your house hygienic. Hence, you need a strong and efficient plumbing system while building your house.
There are three main components of the plumbing concept. They are:
The appliance or fixture set.
The water supply system.
The drainage system.
Usually, a plumber must hold a license for plumbing. In a lot of communities, they do not approve a plumber unless he holds a license. All the houses have a standard plumbing system but then the pipe routing diagram, pipe size or the fixture placement is completely dependent on that individual home layout.
Points to Remember While Building a New House
So before setting the concrete foundation, sewer accommodation stubs need to be set. Rest of the plumbing is done later. Once the framing is done of the house, rough in plumbing starts in conjunction with the installation of the wiring and ducts. This is done before drywall is hung. Next, the main drains are installed in floors and they are connected to the stack. For sinks and tubs, rough in drain fittings need to be installed. Also, toilet flanges need to be set and water supply pipes and tubing has to be installed.Before framing the walls, shower units and tubs are installed because of their larger sizes which can be difficult to set if the walls and doorways are framed. Once these are set, it needs to be protected from getting scratched since a lot of construction is going to take place. You can use an old blanket or a cardboard to cover such fixtures. Once the floors and the walls are completely done, you can set and connect the commodes and the sinks.
Water supply system is the backbone of the house. So, once it enters the house, it gets split into two lines. One of these lines gets connected to the water heater which is used for hot water supply and the other one simply supplies cold water. These lines further supply water to the appliances and fixtures.You can also use a water supply manifold system. It features a large panel with blue valves on one side and red valves on the other side. These valves keep a control on each cold or hot tube which is used to supply water to all the fixtures and appliances. Thus, if you shut off the supply of water of one tube then it will not hamper the water supply to rest of the fixtures.
Drainage pipes need to be installed vertically from the ground to the rooftop. These are usually 4 inches in diameter. So, these pipes connect to the stack and direct all the wastes downward and dispose it to the main sewer drain. This is eventually exited out of the house and disposed to the main municipal sewer system. Also, it can be disposed to a personal septic system.Vent pipes of at least 2 inches in diameter needs to be connected to the stack in the attic. This can provide ventilation to the drains, other water blocks can be formed in drainpipes and as a result, it will cause clogs. When a common vent is too far from the fixture, you can use an extra vent pipe for connecting to the stack and separately exiting the roof which is completely dependent on the layout of the house.
A drain trap is used for connecting to the shower, bottom of the sink or a tub drain. This pipe is in U shape which prevents the house from the odor of the sewer gasses by retaining a small amount of water. Drain traps are mandatory for all the plumbing fixtures. The only exception is a commode which usually has a built-in internal trap linked to its base.
