Plumbers not only install water, heating and gas sytems, but also test them to ensure they are working properly. A plumber is required to repair appliances which are connected to water supply and drainage systems. They may need to repair cracked pipes or a heater that has broken down. Appliances which burn fuel and boilers are quite complex and therefore require regular servicing, normally once a year.
