House connection is a plumbing installation that connects a home to the public water supply and sewer system. It is necessary for homes to have house connections in order to access these utilities. House connections are also known as service lines, since they provide a line of service between a home and utility infrastructure. The process of installing a house connection involves laying down pipes from the utility line into the property, connecting it to the main water supply, and ensuring that it meets local regulation standards. Once installed, plumbers typically use standard fixtures such as taps and valves in order to control the flow of water within the house connection system. Plumbers may also use specialized plumbing materials such as plastic or copper tubing depending on their needs. Additionally, some house connections require additional components like backflow preventers or pressure reducing valves in order to ensure safe usage of water within the home.
