Every home has a different setting and configuration, hence the working of the residential plumbing system is different according to each household.

If you have plans to carry out plumbing work in your home, then it’s required that you understand the basics of your home’s plumbing system. In this article, we’ll discuss some things you should know about your residential plumbing. 

How Does Residential Plumbing Work

What is Plumbing?

The residential plumbing system consists of two major systems which include the water supply system and drainage system.

  • Water Supply System

The water supply system is designed to bring fresh and clean water into the home. If you buy water from your community, it is supplied through the main pipeline that runs alongside your street. The water then passes through a smaller supply line that runs through your home. Every plumbing pipe running through your home is yours to install and maintain.

  • Drainage System

Your drainage system and water supply system are the major plumbing systems in your home, however, they’re connected in any way. Instead, plumbers use fixtures such as sinks, faucets, washing machines, etc to bridge the gap. The water supply system will bring in water into these fixtures and the water the water leaves using the drainage pipes. The incoming water is mainly pressurized, but your drainage system only requires water to flow out through a series of pipes, traps, and vents.

Interior Plumbing: The Kitchen

Your kitchen plumbing is usually done in conduit style; this means that the pipes are hidden behind the walls or beneath cabinets. The kitchen plumbing consists of cold water lines (connected directly to the main supply lines) and hot water lines (connected to the water heating system). You may also connect other items such as dishwashers, coffee makers, or ice makers to your incoming cold water supply line. But other fixtures such as sinks and faucets are connected to your drainage system which allows water to flow out of the house.

Interior Plumbing: The Bathroom

Your bathroom faucets, sinks, and showers get their supply of water from the cold water line. In some homes, they use a secondary source to fill their toilet tanks; however, most homes fill their toilets from the main supply line. The drainage system in your toilets and bathrooms is connected to the same lines that lead water out of your kitchen sink. This is why then there’s a clog, it affects almost every part of the drainage system.
