6 Facts About Everyone Thinks Are True

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.
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.
The plumbing fixtures sometimes need to be set before the walls are framed mainly due to their large size with examples being shower units and tables where you should then cover them with cardboard, rugs or blankets to avoid damage, after which you should finalize by setting the sinks and commodes after framing the walls and laying the floor.
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 consists of one stack that runs from below the ground floor up to the roof line collecting waste from each floor and directing it down to the main sewer drain which exits the home in the frost line and is connected to a personal septic system or the municipal sewer system.
There should also be ventilation, which prevent water locks that cause clogs, and this is done by installing a vent behind sinks. 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.
