Plumbing is a very important part of a construction project, whether it’s a residential or commercial property. It is an industry that has been around for centuries. Modern plumbing has advanced in leaps and bounds, and there are now associations to regulate the profession. The job of a plumber involves keeping buildings and homes clean and safe to live in.

Modern plumbing involves installing and maintaining systems of pipes and drains to transport water and waste. This type of work is highly technical, and can involve a range of special skills. For example, plumbing contractors may install a water heater or repair a backflow preventer. The plumbing industry is an integral part of any developed economy due to the need to ensure clean water supply and sanitary waste collection.

There are different types of pipes for different applications. PEX pipes, for example, are flexible and can be woven through walls. They also withstand pressure well, and are usually color coded to distinguish between hot and cold water. Another type of pipe is ABS pipe, which looks like PVC pipes but is black in color. It is particularly resistant to cold weather, and is usually used in drain and vent lines.

The biggest problem with drain water systems is clogging. This can be prevented by cleaning plugs regularly. You should also keep an eye out for leaks from drain water vents. Leaks can make your house stink, and they can result in structural damage. A leak can also lead to expensive water bills.
