At Call Out Plumbers, we understand the importance of maintaining a fully functioning plumbing system in your home. Many homeowners overlook the significance of their plumbing until it becomes a major issue.

To help you better understand your home plumbing system, we’ve created this comprehensive guide. From the water supply to the drainage system, we’ll cover everything you need to know to keep your plumbing running smoothly.

Water Supply

Your home’s water supply is the source of all the water that flows through your taps, showerheads, and appliances. Most homes are supplied with water from a municipal supply, while some rely on private wells.

The water supply enters your home through the main water valve, which is typically located near the water meter. From there, the water flows through the main water line and into your home’s plumbing system. It’s essential to know where your main water valve is located so that you can quickly shut off the water in case of an emergency.

Pipes and Fixtures

Your home’s plumbing system is made up of pipes and fixtures that work together to distribute and drain water. Pipes are typically made of copper, PVC, or galvanized steel and come in different sizes to accommodate various water flow rates.

Fixtures, such as taps, showerheads, and toilets, are connected to the pipes and allow you to control the flow of water. It’s important to keep these fixtures in good working condition to prevent leaks, which can lead to water damage and other issues.

Drainage System

The drainage system in your home is responsible for removing waste and wastewater from your fixtures and appliances. The system consists of pipes, vents, and traps that work together to transport waste to your home’s sewer or septic system.

The drainage system is designed to prevent foul odors from entering your home by using traps, which hold water to create a seal and prevent sewer gas from entering your home. Regular maintenance of your drainage system, such as removing clogs and debris, is crucial to prevent backups and other issues.


To keep your plumbing system in good working condition, regular maintenance is essential. Some tips to maintain your plumbing system include:

  • Regularly inspecting pipes and fixtures for leaks and other issues
  • Checking and cleaning fixtures to ensure proper flow
  • Avoiding flushing non-degradable items down the toilet
  • Properly disposing of cooking oils and grease
  • Regularly scheduling professional drain cleaning services
  • Having your plumbing system inspected annually by a licensed plumber


By understanding your home’s plumbing system, you can prevent costly repairs and avoid any plumbing mishaps. Remember to perform regular maintenance and inspections to keep your plumbing running smoothly. If you have any questions or concerns, don’t hesitate to contact a licensed plumber for assistance.
