Every building has an elaborate plumbing system, but few people take the time to learn how they work. In fact, its seems like the only time people think about their plumbing systems is when they have a problem. A typical house has four systems that make up the plumbing system. These are; cold water supply, hot water supply, sewerage and gas supply systems. An accredited plumber is the most qualified person to install, repair and maintain these plumbing systems.

Cold Water Supply System

This is the main water supply system in any building. During construction, the plumber connects a copper, or plastic, water pipe to the city’s main water supply line. The pipe connects to a water meter before it branches off into several water pipes that connect different cold water outlets to the main water supply. A certified plumber would also install emergency stop valves in different parts of the house. For instance, there should be one for the bathroom and another in the kitchen. In case a tap gets damaged, or a pipe bursts, you will not need to run outside to turn the main shut-off valve.

Hot Water Supply System

The main component of this system is the hot water heater. The tank has a cold water inlet and a hot water outlet as well as a heating system that can either be electric or gas-powered. Whatever the case, cold water is heated to the desired temperature and sent to hot water taps and showers through a network of hot water pipes. These pipes should be insulated to minimize heat loss. Nowadays, there are electric shower heads, which heat water instantly when you run the shower. There are also tank-less water heaters, which heat water when hot water taps and showers are opened. These water-heating systems are considered much more energy-efficient as they produce hot water instantly.

Drain System

This is one of the most important systems in any plumbing system as it takes out used water and semisolid wastes. There is usually a main drain pipe outside the house, which takes all the effluent from the house into the city’s sewer system, or a septic tank. A network of drain pipes, from the kitchen sink, washing machine, toilets, bathroom drain and bathtub, take effluent to the main drain pipe. Since there are usually foul gasses inside the sewer system, a P-trap is usually installed at the mouth of each drain in the house. Accredited plumbers normally install at least one vent in the sewer system to expel sewer gases and allow for smooth flow of effluent inside the drains by making sure the pressure inside the sewer system is the same as atmospheric pressure.

Gas Supply System

The average home uses gas for cooking, water heating and space heating. Since the plumbing is usually similar to the water supply system, an accredited plumber is the best person to design and install the gas supply system. Flexible stainless steel and flexible copper pipes are the most popular pipes for gas supply lines, but black iron pipes can also be used.
