Even though residential and commercial buildings have evolved over the decades there are three main types of plumbing systems used throughout. These are made up of a combination of different pipes, subsystems, fixtures, joints and parts. Local Plumbers London are here to go through each plumbing system so you know if your property’s water usage is as effective as it can be and if you need a local plumber to help you or not.


Supply Lines

This system involves piping lines which supply and transfer clean hot and cold water from your boiler or water tank to the desired outlets within your home or building. Outlets such as bathrooms and kitchens which have taps, showers and faucets. This supply system is usually made of piping made of copper, plastic and or plastic resin called Polybutylene. Another aspect about the supply line system is the use of a water motor which supplies the pressure to move the water to the necessary outlets. The use of a water motor will depend on the position of your water tank and how much gravity is acting against the water flow or direction of the piping subsystems.


Water Drains

Drainage systems are designed to transport waste water from your outlets to external or public drainage lines. A combination of iron or CPVC pipes create pressure either in single pipe arrangements – often known as the soil stack used within modern buildings, or two-pipe arrangements – common within older types of buildings, is the general setup of a drainage system. For single pipe arrangements, all of the basins, baths, showers and toilets will flow towards this main drainage pipe. Two-pipe arrangements involve the waste and soil water being kept separate until they reach the underground drain.



Vent drains are the third type of drainage system and usually positioned at building roof tops and are important because plumbing systems often store toxic gasses which should not tarnish the clean water or restrict waste water flow.


It’s good to know about these plumbing systems because efficient plumbing systems can not only save you money but can prevent fixing costs in the future. It can also help you and your local plumber target any potential problem areas so you can put the necessary preventative measures in place. Bear in mind that the home or building owner must take responsibility of their drainage system to the point where it enters the main sewer. In addition, drainage system are a part of Building Regulations and not your water company and therefore enforced by your local council. If you need to modify any part of your draining system then your Building Control officer must be consulted.
