The most important function of a drainage system is to convey used water to the sewage system. If you’re wondering what drainage is, the easiest way to remember it is that all used water leaves your house through pipes.
It’s important to understand that your drain pipes only work by gravity. The closer the drainage system is to the vertical pipes, the faster and easier the water will move away. Since this is often difficult to achieve in standard home construction, most drain pipes are angled to keep used water flowing toward sewage. In today’s guide, we’ll take a look at what drainage systems are and eight of the best drainage system manufacturers in China. Read on to learn more.
1. How drainage systems work
It’s easy to understand how a drainage system works. It works entirely on gravity and does not use any pressure to move water through the pipes. All water appliances, sinks, and toilets in the home are connected by pipes.
When you flush or turn on a faucet, wastewater first enters a small pipe in your home and then connects to a larger sewer pipe down the road. This sewage then flows into the municipal sewer network and all enters the sewage treatment plant.
2. House drainage parts
It is crucial to be familiar with most of the components of your drainage system when needed. Most drain parts and components are well hidden under our sinks, behind walls, or under floors, but knowing which component is responsible may save you time, effort, and potentially money.
- Fixed Drain – This is the visible part of the sink or shower drain that everyone is familiar with. It is open and usually comes with some blocking mechanism.
- U-Bend or P-trap – Immediately after the unit drains, there is a P-trap, usually a curved pipe in the shape of the letter “P” or “U.” It holds standing water and prevents sewage gases from rising.
- Toilet Trap – Sometimes built-in, a toilet trap is similar in shape and function to a P-trap – it blocks sewage gases.
- Washing Machine Standpipe – While most washing machine ducts may be hidden, standpipes are often exposed. The washing machine drain pipe carries the water up to the standpipe and then into the waste pipe.
- Branch drains – These run horizontally and connect a fixed drain elbow to the main drain pipe. They are usually hidden behind walls.
- Main Drain – Hidden beneath your foundation slab or basement floor, the main drain connects to the municipal sewer line and carries all of your home’s wastewater into it.
- Pipe Shutoff – A shutoff valve is usually located near the water meter and must prevent flooding or water damage.
