Guide to Installation of Plumbing in a New Home
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.
Below is an explanation about the processes of installation of each plumbing components and the other hand, the timetable is detailed out in a way that the drainage system is set first, before the concrete foundation has been laid, then comes the duct installation and rough-in plumbing, which is done alongside wiring, after the installation of the wall frame but before the dry wall is installed, and after that, you need to install the main drains in the floor, install the water pipes, tubing and toilet flanges and install the sinks.
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 has pressurized water coming in in two lines where one supplies cold water and the other is directed to the water heater and each fixture and appliance is then connected to both hot and cold water while some homes have a water supply manifold system that has large panels that have both red and blue valves with each valve controlling one cold or hot water tube supplying water to the fixture and this makes it easy to end supply of water to a single appliance without shutting out supply to the entire house.
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. Drain traps are also essential to prevent gases from the drainage systems from getting back to the house by retaining some water in the neck of their u-shape and they are installed under sinks, showers and tubs.
