Systems that convey waste, gas, and water are essential components of contemporary infrastructure, and plumbing work is an integral part of this. All types of buildings use it to ensure the smooth and incident-free operation of their water supply and sewage systems.

What is plumbing work basics?

A building’s plumbing system consists of the fixtures, pipes, and other equipment put in to distribute water and remove waste. These are some of the basics of plumbing work.

  1. Water Supply System
  • Types of pipes

Some of the most common materials used are galvanized steel, PEX, PVC, and copper.

To keep sewage gases out of the building, there is a U-shaped pipe that runs beneath sinks and other water fixtures.

  • Purpose

Various appliances and fixtures can empty it into the septic or sewer system.

  •  Components

Vents, drains, pipes, and traps.

  1. Fixture installation

Three Stages of New Construction Plumbing

There are multiple steps involved in new building plumbing to guarantee a safe, efficient, and dependable system. The three main steps in the plumbing process are as follows:

  1. Groundwork

This stage involves laying the foundation for the plumbing system. Usually, we pour the foundation before this stage.

  • Inspection

A building inspector verifies that the rough-in plumbing work satisfies all regulations in the area.

  • Water Supply Lines

Putting in the pipes that provide water from the mains to the residence.

  • Sewer and Drainage Lines

The process involves installing sewer lines and subterranean drainage systems. This includes branch lines and major sewer lines.

  • Site Preparation

Grading and excavation may be necessary to prepare the site.

  1. Top-Out

Upon completion of the framing but before wall closure, this stage entails inserting plumbing components into the ceilings and walls.

  • Inspection

Everything is double-checked to make sure it follows all the rules.

  • Appliances and Fixtures

Installing rough-in fixtures such as shower pans and bathtubs.

  • Drain, Waste, and Vent System

Putting in pipes for venting and waste removal.

  • Water Lines

The process involves connecting plumbing devices such as showers, toilets, and sinks to the water main.

  1. Final Plumbing

This finishing phase involves placing the appliances and plumbing fixtures that are visible to the eye after the floors and walls are complete.

  • Installation of Fixtures

This entails installing faucets, toilets, sinks, and other plumbing fixtures.

  • Water Heater

Installation of and connecting the water heater.

  • Appliances

Connecting appliances such as water filters, washing machines, and dishwashers.

A thorough examination of the plumbing system is conducted to ensure its efficiency, correct drainage, and the absence of leaks.

  • Final Inspection

During the final inspection, everything is double-checked for proper installation and functionality, as well as conformity with regional construction regulations.

These phases ensure the proper, effective, and code-compliant installation of a building’s plumbing system. This gives the facility a dependable waste management and water supply system.

Three main types of plumbing

  1. Water Supply System
  • Galvanized steel, PVC, copper, and PEX pipes are the only ones used.
  • The system that transports water from a public or private well includes the necessary fixtures, fittings, pipes, and valves.
  •  Brings potable water to residences and other structures.
  1. Drainage System
  • uses cast iron pipes, PVC, and ABS often.
  • The system of pipes and fittings that lead wastewater from fixtures like appliances, toilets, sinks, and showers to a municipal sewer system or septic tank.
  •  Clears buildings of sewage and wastewater.
  1. Gas Plumbing System:
  • Corrugated stainless steel tubing, copper, black steel, and brass are common materials used.
  • This category encompasses gas regulators, fittings, pipes, and valves.
  •  Delivers gas, either propane or natural, to home appliances for use in heating, cooking, and cooling.

To make sure these systems work and are safe to install, you need to use certain materials and follow certain procedures.


Plumbers need to be well-versed in various building codes and regulations, as well as skilled with a wide range of materials and tools. They must also be able to read and understand technical drawings and blueprints when it comes to plumbing work. To ensure the legal and safe operation of their trade, plumbers are frequently required to get specific certificates and licenses.
