1. Supply System

The supply system in your house is responsible for bringing clean treated water into your home for drinking cooking showering and other everyday activities. This system consists of –
  • Pipes – These are the main conduits that carry water from the municipal water supply or a well into your home. Pipes are typically made of materials such as copper PVC or PEX.
  • Shut off valves – These valves allow you to shut off the water supply to specific fixtures or areas of your home in case of a leak or other emergency.
  • Water heater – This appliance heats water for use in showers sinks and appliances like dishwashers and washing machines. Water heaters can run on electricity gas or propane.
  • Fixtures – These include sinks toilets showers and tubs where you access the water supplied by the system.
The supply system is essential for providing clean water for daily activities and ensuring that water pressure is consistent throughout your house.

  • Vents – These pipes allow air to enter the drainage system preventing vacuum pressure and ensuring smooth drainage. Vents are usually located on the roof of your house.
