Understanding the Basics of Plumbing Systems

In any building, the plumbing system is a network of pipes, drains, fittings, and valves designed for one central purpose: to distribute potable water for consumption and domestic use, and to effectively remove wastewater. It’s critical to understand the basics of a plumbing water supply system, as it has a direct impact on the health and safety of the building’s occupants.

Definition and Purpose of a Plumbing System

A plumbing system is an interconnected network designed to manage the flow of water in and out of a building. The main function of this system is to provide clean, potable water for drinking, cooking, cleaning, and bathing. At the same time, it efficiently removes wastewater and sewage, thus maintaining hygiene and preventing waterborne diseases.

The Three Main Types of Plumbing Systems

There are three primary types of plumbing systems in any building: potable, sanitary, and stormwater.

  1. Potable Plumbing System: This system transports clean, drinkable water from the municipal supply or other sources to various points of use within the building. It’s crucial to ensure this system is free from cross-connections with wastewater to prevent contamination.
  2. Sanitary Plumbing System: This system handles the removal of sewage and wastewater from the building. It includes fixtures like toilets and drains, and pipes that lead to the sewer or septic system.
  3. Stormwater Plumbing System: This system manages the flow of rainwater. It includes roof gutters, downpipes, and drains, directing stormwater away from the building to prevent flooding and water damage.

Key Plumbing Terms

Understanding common plumbing terms can help you better comprehend how a plumbing water supply system works:

  • Backflow: This is an unwanted flow of water in the reverse direction, which can contaminate the potable water supply.
  • Back Siphonage: This occurs when negative or reduced pressure in the water system causes water to flow back into the distribution pipes.
  • Branch: A pipe in the plumbing system that extends from a soil, waste, or vent pipe to connect directly with a fixture.
  • Building Drain: The lowest part of a drainage system that receives discharge from soil, waste, or other drainage pipes inside the walls of the building.
  • Drain: A pipe that carries waste and waterborne wastes in a building drainage system.
  • Interceptor: A device designed to separate and retain deleterious, hazardous, or undesirable matter from normal wastes while permitting normal sewage or liquid wastes to discharge into the drainage system by gravity.
  • Potable Water: Water that is suitable for drinking.
  • Septic Tank: An underground tank where sewage is collected for it to decompose through bacterial activity before draining by means of a soakaway.
  • Trap: A fitting or device that provides a liquid seal to prevent the emission of sewer gases without materially affecting the flow of sewage or wastewater through it.
  • Vent Stack: The vertical pipe installed to provide air circulation to and from the drainage system and to protect the trap seals from siphonage and back pressure.
  • Water Flow Controls: Devices or technologies used to regulate the flow of water in a plumbing system.
  • Water Supply System: A system of pipes, fittings, valves, and fixtures that conveys water from the water source to the building’s interior.

Components of a Plumbing Water Supply System

The plumbing water supply system plays a crucial role in delivering potable water to the various fixtures within your home or business. This system is more than just a network of pipes, it’s a well-planned and organized arrangement that ensures efficient water flow. Let’s delve into the key components of this system.

Overview of the Water Supply System in Plumbing

The water supply system is a network of pipes, fittings, and valves that convey water from the source to your taps, showers, and appliances. This system is designed to maintain the right water pressure, ensuring a steady flow. It can be broken down into several key components: pressure pipes, pipe junctions, water sources, and end-users.

Role of Pressure Pipes, Pipe Junctions, Water Sources, and End-Users

  • Pressure Pipes: These pipes carry water from the source, whether it’s a municipal water supply, a private well, or a reservoir. The water pressure within these pipes ranges from 35-75 PSI (pounds per square inch), with the ideal range being 40-60 PSI.
  • Pipe Junctions: Junctions are the points where pipes branch out, allowing water to be directed to different areas of the property. Each branch should ideally have a shutoff valve, allowing water to be cut off to a specific area without affecting the rest of the property.
  • Water Sources: The source of your water supply can be a municipal water supply, a well, or a reservoir. The water passes through a curb valve near the street, which is typically owned by the city, before entering your property.
  • End-Users: These are the various fixtures and appliances within your property that use water, such as sinks, showers, toilets, and washing machines.

Hierarchical Arrangement of Water Supply System

A well-designed water supply system follows a hierarchical arrangement. It starts from the water source, travels through the main supply line, and then branches off to various parts of your property.

The supply line first feeds into the water heater, creating a parallel hot water main. From here, secondary branches of hot and cold water snake through your property, reaching every fixture. This kind of system ensures that water pressure is maintained and every fixture receives an adequate water supply.

At Go Pro Plumbing, we have extensive experience designing and maintaining effective water supply systems. We ensure that every component, from the pressure pipes to the end-users, is working efficiently, providing a reliable water supply for your home or business.

Materials Used in Plumbing Water Supply Systems

In the world of plumbing, the material of your pipes plays a crucial role in the overall efficiency and durability of your plumbing water supply system. Not all materials are created equal, and understanding the differences can help you make informed decisions about your plumbing needs. Here at Go Pro Plumbing, we work with various pipe materials, each offering unique advantages.

Galvanized Steel

Galvanized steel pipes were once the most common type for water supply lines. They’re made of steel and coated with zinc to prevent corrosion. While durable, they can be labor-intensive to install and typically have a lifespan of about 40 years. If your home was built before the 1960s, you might have these pipes in your system.

Pros: Durable and resistant to rust.
Cons: Labor-intensive to install, has a limited lifespan.


Copper is a popular choice for both hot and cold water distribution. It’s long-lasting, resistant to corrosion, and works well in both underground and above-ground applications. However, as copper ages, it can thin out, leading to leaks. Plus, it’s more expensive and requires more labor to install than some alternatives.

Pros: Long-lasting, resistant to corrosion.
Cons: Can thin out over time, more expensive than other options.


PVC, or polyvinyl chloride, is commonly used for drainage but is rarely used for potable water applications due to safety concerns. PVC pipes are often white and can come in various colors to indicate their use.

Pros: Cost-effective, lightweight.
Cons: Not safe for drinking water in many jurisdictions.


CPVC, or chlorinated polyvinyl chloride, is a type of PVC that’s been chlorinated via a free radical chlorination reaction. This process makes it safe for potable water and also boosts its temperature resistance.

Pros: Safe for drinking water, resistant to high temperatures.
Cons: Less durable than metal pipes, can become brittle over time.


PEX, or cross-linked polyethylene, is a type of plastic that’s becoming increasingly popular for water supply lines. It’s flexible, easy to install, and resistant to both freezing and high temperatures. It’s also less prone to leaks because it doesn’t require as many joints.

Pros: Flexible, easy to install, resistant to freezing and high temperatures.
Cons: Cannot be used outdoors as it degrades in sunlight.

At Go Pro Plumbing, we understand the importance of choosing the right materials for your plumbing water supply system. Regardless of the type of pipes in your home or business, we’re here to provide top-notch services to ensure your system remains efficient and reliable.

Types of Hot Water Delivery Systems

To maintain an efficient plumbing water supply system, it’s essential to understand the various types of hot water delivery systems. Primarily, there are four basic types: trunk and branch, core, whole-house manifold, and demand hot water delivery systems. Each system has its unique configuration and concept, designed to cater to different needs and preferences.

Trunk and Branch Systems

Trunk and branch systems are the most traditional hot water delivery system. This system operates on a simple principle. It comprises a large (trunk) pipe that runs the hot water from the water heater to multiple smaller (branch) pipes. These branch pipes then deliver hot water to the fixtures throughout the house. It’s a straightforward, cost-effective system that’s easy to install and maintain. However, it may take a while for the hot water to reach the furthest fixtures due to the distance from the water heater.

Core Systems

Core systems, also known as home-run systems, take a unique approach to hot water delivery. In this system, each fixture has a dedicated line running directly from the water heater. This direct line ensures that hot water reaches the fixtures faster and maintains a steady temperature. While this system may require more piping, it can significantly cut down on water and energy waste by reducing the waiting time for hot water.

Whole-House Manifold Systems

Whole-house manifold systems are a type of home-run system that uses a central manifold to distribute water to each fixture. Each line running from the manifold to the fixture is the same length, ensuring equal water pressure and temperature at all fixtures. This system is incredibly efficient and minimizes water and energy wastage. However, it may be more expensive and time-consuming to install due to the extensive piping required.

Demand Hot Water Delivery Systems

Demand hot water delivery systems, or tankless water heaters, provide hot water only when needed, making them a highly efficient choice. When a hot water tap is turned on, cold water travels through a pipe into the unit, where a gas burner or electric element heats the water. Consequently, these systems deliver a constant supply of hot water without waiting for a storage tank to fill up. They can save energy and reduce costs, but upfront costs may be higher than traditional systems.

At Go Pro Plumbing, we’re experts in installing and maintaining all these types of hot water delivery systems. Our experienced team can help you choose the best fit for your home based on your individual needs, ensuring you always have a reliable and efficient plumbing water supply system.

Plumbing Building Codes and Standards

In the world of plumbing, understanding codes and standards is crucial for the safety and efficiency of a plumbing water supply system. These rules exist to ensure that every plumbing installation, repair, or maintenance project meets a set of minimum requirements.

Decoding the Plumbing Jargon: Codes, Standards, and Licenses

Building codes are mandatory regulations set by local or national authorities. They define the minimum acceptable levels of safety for buildings, including plumbing systems. A building standard, on the other hand, is a set of guidelines developed by industry experts. While not legally required, standards outline best practices for design, installation, and maintenance of various building systems, including plumbing.

A plumber’s license is a credential that proves a plumber has undergone the necessary training and has the expertise to carry out plumbing work in compliance with local codes and standards. As a licensed plumbing company, Go Pro Plumbing is committed to providing services that meet and exceed these requirements.

The Importance of Complying with Plumbing Building Codes

The building codes relevant to your plumbing water supply system depend on your climate zone. For example, in regions where freezing temperatures are common, the codes might require specific insulation for pipes to prevent freezing and bursting.

Compliance with these codes is crucial. It not only ensures the safety and longevity of your plumbing system but also avoids potential fines or penalties for non-compliance. Additionally, if your plumbing system isn’t up to code, it can negatively impact the value of your home or business.

The EPA WaterSense® New Home Specification

The EPA WaterSense® New Home Specification is a set of water-efficiency criteria for new and significantly renovated homes. These guidelines can help reduce a home’s water use by approximately 20% compared to traditional homes.

By incorporating WaterSense® approved fixtures and energy-efficient appliances, we can help build a home that not only meets local building codes but also conserves water and energy. This not only benefits the environment but can also result in significant cost savings over the life of the home.
