The Basics of Residential Plumbing
Plumbing can be understood through understanding nature. It follows the basic laws of gravity, pressure, and finding its own level. When you think of plumbing like this, you can understand the way it works and are better able to make fixes to your home’s plumbing system.
The plumbing system in your home is composed of two separate subsystems. One subsystem brings freshwater in, and the other takes wastewater out. The water that comes into your home pressurized to create flow so that it can travel through city plumbing to your house.
In order to source cold water, you simply need to tap into the main water supply. However, if you need hot water, you must heat your water in your home with a hot water heater. One pipe carries water from the municipal water system to your water heater, where a hot water line carries the heated water to all the fixtures, out-lets, and appliances in the home.
When it comes to wastewater systems, there are two basic systems that are used. Whether your home is on a sewer or septic system, the systems within your home are essentially the same. Drainage systems are not pressure dependent like supply systems, and are instead run through the pull of gravity. This is because all pipes that are installed for drainage are angled at a pitch, or downward direction. The sewer line continues this downward flow to a sewage treatment facility or a septic tank.
While this system may sound simple, it actually relies on other contributing functions to ensure proper drainage, which includes vents, traps, and clean outs. The vents stick up from the roof of houses to allow air to enter into the drainpipes to ensure proper flow. Traps are vital components of the drainage system. If you look you can see traps under every sink. They are the curved or S-shaped section of pipe under each drain.
Drainage systems involve all of these components and is usually referred to as the DWV or the drain-waste-vent system. In order for water to flow freely and waste to exit properly, all components of the DWV must be present and functional.
The supply and drainage subsystems are two distinct and separate systems. There are bridges between the two, however, and the bridges are what make the plumbing system worth having. In plumbing jargon, any bridge between the supply and drainage systems is a fixture.
Toilets, sinks, and tubs are fixtures. In addition, an outside faucet is a fixture and so is a washing machine. All devices that draw freshwater and discharge wastewater are fixtures, and all are designed to keep the supply and drainage systems strictly segregated.
