How to Install Plumbing in a New House
Working on the simple water in and out concepts, plumbing entails three things namely; the water supply system, the appliances and the drainage system, which varies depending on the location but in most places, the procedure of plumbing is dependent on the local plumbing codes and the layout of the building with some communities requiring the installer to be a licensed plumber or to be working under the instructions of a licensed one.
With the following paragraphs giving more information about each installation, the timetable is normally set that; the installation of the sewer accommodation stubs comes first before the concrete foundation has been laid, rough-in plumbing and duct installation comes in next when the wiring is being done after the wall framing has been set up but the dry wall has not been installed, and you should finally put the main drainage in the floor, install the water pipes, fit in the sinks, toilet flanges and tubing.
For the plumbing fixtures, most of them need to be installed before finishing on the walls because most of them are large in size, with examples being bathing tabs and shower units that both require to be covered using old blankets, rugs or cardboard to prevent their damage while finishing on the walls and laying the flooring, after which you should set and connect commodes and sinks.
The water supply system consists of pressurized water that come in two lines, with one taking water to warm in the heater, and the other bringing in cold water to every appliance just like the one from the heater does, but other homes have water supply manifold system, which has blue and red valves that control cold or hot water entering the fixture and this is advantageous because it makes it easy to shut out the supply of water to only one appliance when there is need to without having to shut out the entire house from water supply.
The drainage system mainly has a main stack that runs from below the ground floor to the top as the backbone where it takes waste from each floor and takes it downwards to the main sewer drain, and then exit the house below the frost line where it is connected to the municipal sewer system or is directed to a personal septic system.
Without a constant supply of air, there can be water locks in drainpipes which cause clogs, and a single vent behind a sink is installed to act as ventilation. Below the sinks, showers and tub drains, are drain traps that help prevent sewer gases from getting back to the house by retaining some water in their u-shape.
