How to Install Plumbing in a New House
Plumbing requires to be done by a licensed plumber or a person working under a licensed plumber in most places and the process is dependent on the plumbing requirements of the locality and the house layout of the individual but it is always done in the simple concept of water in and water out and involves three components namely the appliances, the drainage system and the water supply system.
The sewer accommodation stubs, which are part of the drainage system are set before the concrete foundation is laid with the other part of plumbing being done later, the duct installation and rough-in plumbing takes place next alongside wiring after the wall framing has taken place but the dry wall is yet to be hang, after which you should put in place the main drains in the floor, fit in the sinks and install the water pipes, tubing and toilet flanges, and the following paragraphs gives details about each installation.
Plumbing fixtures need to be installed before you have set the walls, which is mainly caused by how big they are such as how shower units and bath tabs are and should be covered using soft or hard materials like rugs, cardboard or old blankets to avoid damage while finishing on the walls, after which you should 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 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.
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.
