Written by on January 9, 2022 in Home Maintenance, Repairs & Improvement with 0 Comments

Home plumbing is a complex system of pipes, even in a small house. If you are ever to need Blocked Drain Repair Strathfield services, it is a good thing to have some knowledge of your home’s plumbing system. There are a number of sub-systems in a residential plumbing system, with the incoming clean water and the outgoing drain water systems being the main ones. This guide introduces these different systems and their key features and components.

Water Supply System

Your home’s water supply system is responsible for routing municipal water to your home. The supply then routes water to different outlets in your home, including faucets, toilets, showers, bathtubs, and appliances. The components of this system include:

  • Water pipes
  • Service valves
  • Fittings
  • Faucets

These components can be made of PVC, galvanized iron, or copper.

Drain Water Vent System

The Drain Water Vent (DWV) System, as the name suggests, carries wastewater and sewage from your home to the public sewer or septic tank. It will remove sewage or wastewater from bathtubs, sinks, toilets, showers, and appliances such as washing machines, and dishwashers.

These two home plumbing systems are designed not to overlap. There are 3 key components to the DWV systems:

  • Drain Pipes: These components are downward angled pipes that remove water from the fixture to the sewer line. Since the DWV system relies on gravity, it is a more complex system than the water supply system.
  • Drain Traps: These are U-shaped pipes preventing backflow into the plumbing system.
  • Drain Vents: This system runs from the roof and into the drain pipe. It works by releasing air into the plumbing, thus enabling smooth drainage.

Vent pipes are connected to sinks, toilets, and other fixtures to allow sewer gases to move up and out of your home. They also help with air pressure to enable wastes to flow freely.

Kitchen Plumbing System

The kitchen plumbing system most commonly develops issues and requires you to call your Wollongong Plumber. A typical home kitchen plumbing system is moderately simple and includes the following components:

  • Hot/cold water supply lines connected to the faucets
  • Gas supply pipe
  • Waste line for sinks
  • Connections for the dishwasher, icemaker, disposer, and instant hot water

These components are connected to the water supply and/or DWV system.

Bathroom Plumbing System

A home bathroom has its own plumbing system that is connected to the water supply and drain-waste-vent systems. The plumbing system is designed to handle both water delivery and removal from all the fixtures in the bathroom in an efficient and well-organised manner. The common fixtures in a bathroom include showers, sinks, toilets, and bathtubs.

The water intake and removal systems both work together in your home’s plumbing system to ensure efficient operation. The knowledge of these systems will make it easier for you to identify some signs of plumbing issues. This will further make it easier for you to explain an issue to your Plumber whenever you need their services.
