A plumbing system involves pipes, fittings, and faucets that can provide smooth water to a building’s citizens. It is the lifeline of the building. 

Imagine you live in a house where there is no water coming from the pipes or no water to flush the toilet. It adversely affects your daily routine. Again, if unhygienic water comes from your faucet, it will affect your health badly. So, a sound plumbing system is quite essential when building a house.

Now, let’s discuss some other important aspects of plumbing in new construction.

1. Ensure The supply of Clean Water

If you don’t install proper plumbing while building your house, it can pose problems. Poor plumbing can connect sewage pipes to clean water pipes, which can further cause serious health hazards.

A well-designed plumbing system provides clean water which you can use for cooking, drinking, or bathing.

A properly installed plumbing system helps to dispose of wastewater from the building.

The essential components of a new construction plumbing are as follows.

1. New Construction Plumbing Pipes

The plumber will install various pipes in the newly constructed house. Some pipes will supply clean water, which you can use for various purposes, like drinking and cooking. There will also be drainage pipes whose main work is to dispose of wastewater from the building.

The type of pipe used anywhere in your building depends on its purpose and location. For example, if you want to transport hot water in a pipe, use copper pipes as they are heat resistant.

Gas supply lines can consist of black steel because of its robustness properties. The drainage system pipes used in the building consist of PVC or ABS because they are durable and strong.

2. Fixtures

You interact directly with plumbing fixtures in your building. I am listing below some of the fixtures

  • Sink¬†
  • Toilet
  • Appliances in your building that use water of your building like washing machines, dishwashers
  • Faucets
  • Bathtub

The plumber must correctly install these faucets and connect them further to the home pipes.

3. Sewer Lines And Septic Tanks

Sewer lines and septic tanks are the next aspects of the plumbing system. The plumber installed the septic tanks 10-25 feet deep into the building’s ground. A septic tank separates solid and liquid waste. The solid waste stays in the tank and is removed, while the liquid waste is transported to the leach field.

4. Shut off Valves

Every building has shut-off valves that control the entire water supply of a house. But in some houses, you will find shut-off valves for various appliances like toilets. If a plumbing emergency arises, you can quickly turn off the shut-off valve. It will disconnect the water supply from your entire house.

Building Codes And Regulations Of Plumbing

Plumbing or Building codes regulate the design and inspection of various plumbing systems. Most residential buildings follow these codes to ensure that the plumber will adhere to the safety and structural integrity of the building. 

The building codes regulate almost everything, i.e., from the pipe depth to the type of trap used in your building. The primary purpose of building codes is as follows.

  • Building codes specify materials and methods for governing them, helping prevent leakage and water contamination. The plumber must follow the design standards to use the proper pipes, fittings, vents, and other plumbing appliances.
  • The building code provides a technical framework to ensure that the plumbing system installed in your building will work effectively.
  • The building code provides specifications for pipe diameters, pressure limitations, and many more to optimize the performance.
  • The building codes regulation will urge plumbers to use water-efficient fixtures and environmentally friendly installation techniques.

If the plumber does not follow the rules associated with building codes, it may result in legal penalties and fines. The building owners will face various problems, such as getting insurance or selling.

Again, the building may lead to expensive repairs and potential health risks to the occupants. The inspector will inspect the building from the installation stage to the maintenance stage.

So, I recommend that you always depend on professionals. You can consult a good plumber with many years of construction experience.

8. Always Install Plumbing In An Easily Accessible Area
