Whether you’re having a new house built from the ground up or adding onto an existing home, the new bathroom’s plumbing is extremely important. Bathrooms need some extra attention to the plumbing system because they have a toilet, sink/s, and a shower (and possibly a separate bathtub). Therefore a combination of fresh water, sewage, and wastewater need to be handled. Good attention to detail is imperative with any plumbing project.

Follow Your Local Plumbing Codes

The most important rule is to have the bathroom inspected to ensure it meets or exceeds the plumbing code in your area. These codes are based on the National Standard Plumbing Code (NSPC) in the United States. The code is meant to ensure your safety and provides standards for a properly working plumbing system. All local codes must meet or exceed NSPC standards.

A licensed plumber should be familiar with the local codes and have no problems with their work passing inspection.

Think of these inspections as a safety net; meant to double-check the work that has been done. It’s better for any potential problems to be found early on, when they can be easily fixed, rather than when the construction is done and repairs might mean cutting out newly-installed drywall.

The following are some best practices for new construction bathroom plumbing projects. These tips will save both time and money.

1. Know the plumbing code in your area.

This is mentioned again because it’s so important. The last thing you want is to have the work redone because it doesn’t meet the basic standards. The plumbing codes are meant to keep you safe and they ensure the job is done properly. The plumbing inspector will double-check all the work that has been done.

2. Start with a detailed drawing.

Before the first pipe is installed, a diagram of where all drainage and venting pipes will be should be drawn. It must be to scale (or as close as possible), with the correct angles. This drawing is usually given to the plumbing inspector to show how the pipes will be laid out and to show that your work will meet or exceed the plumbing code.

3. Proper venting.

The drainage venting is extremely important. If the vents are too far from the drainage pipes then they won’t vent properly. When the water goes down a drain it can create a vacuum. Vents break that vacuum, allowing water to flow freely.

4. Shutoff valves for every fixture.

Imagine having to turn off the main water line to your house every time there’s a problem. Sounds like a pain, right. Well, it is. Installing shutoff valves for all fixtures and appliances will help isolate problems while keeping the water running in the rest of the house.

5. Use a licensed plumber.

Many licensed plumbers will have the experience installing the plumbing in a new bathroom. Further, they know the “tricks of the trade” and can get the work done in a reasonable timeframe.

Coordination With Other Contractors

It’s imperative that the plumber coordinate with other contractors, like the electrician, to maximize efficiency and avoid getting in each other’s way. Generally, the toilet, shower/bathtub, sinks, vanity, etc will need to be installed before the electrician begins wiring.

Bathrooms are an integral part of every house. It goes without saying that having a functional bathroom with plumbing that is properly installed must be a top priority, regardless if your home is a new construction or you’re building an addition onto an existing home. Getting the bathroom built right the first time will not only save money but prevent a lot of the stress that usually comes with new construction projects.
