Rough-in plumbing is an essential process during a building’s construction or renovation. It involves installing all necessary pipes, drains, and vents before walls are closed with drywall. This ensures the plumbing system is in place and ready for fixtures later.
If you’re unfamiliar with rough-in plumbing, don’t worry we’ve got you covered! This article will walk you through the key steps involved in this crucial process.

Step 1: Plan your layout
Before beginning any construction work, it’s crucial to have a well-thought-out plan in place. This is especially true when it comes to rough-in plumbing. Your plumbing layout should minimize the amount of piping needed while still meeting all code requirements.
Using your building plans, identify where fixtures such as sinks, toilets, and showers will be located. You can determine the best supply lines and drainage pipe routes from there. It’s essential to take into account factors such as access to water and sewer mains and any obstacles or obstructions that may affect the placement of your plumbing.
Step 2: Install supply lines
With a solid plan in place, it’s time to start installing supply lines. These are the pipes that deliver hot and cold water to your fixtures. When laying out supply lines, it’s crucial to ensure they are appropriately sized for the intended fixtures and have enough clearance to fit comfortably within walls.
Copper, PEX, or PVC are common materials for supply lines. Each has benefits, and choosing the right one for your project is essential. Copper is a durable and long-lasting option, but it may be more expensive than other materials.
Step 3: Install drainage pipes
Once supply lines are in place, it’s time to move onto drainage pipes. These pipes carry wastewater from your fixtures and home through a main sewer line or septic system. Like supply lines, drainage pipes must be appropriately sized and placed to ensure proper flow and prevent clogs.
When installing drainage pipes, it’s essential to consider their slope. They should be positioned at a slight downward angle towards the main sewer line or septic system to allow gravity flow. Improperly sloped pipes can lead to standing water and blockages in your plumbing system.
Step 4: Add vents
Vents are essential to any plumbing system. They allow for proper air circulation and help prevent unpleasant odors from escaping into your home. These vents run vertically from your drainage pipes through your home’s roof, allowing air to enter the system and maintaining pressure balance.
When adding vents, it’s important to follow local building codes and ensure they are properly spaced for the size of your pipes. Vents can also be used with drainage pipes to create a trap, preventing sewer gases from entering your home.
Step 5: Test your system
With all the necessary components, it’s time to test your plumbing system. This allows you to identify leaks or issues before drywall closes walls. To perform a test, turn on the water supply and run fixtures such as faucets and toilets to check for proper flow and drainage.
If any problems arise during testing, address them before moving on to the next step. Fixing problems at this stage will save you time and money in the long run.
Step 6: Close up walls
Once your plumbing system has been tested and verified, it’s time to close up walls with drywall. This is an essential step as it not only completes the appearance of your space but also protects your plumbing from damage or accidental punctures.
Before closing up walls, ensure all fixtures have been securely installed, and there are no visible leaks or issues with your plumbing system. It’s also a good idea to take pictures of your rough-in plumbing for future reference in case any problems arise.
Conclusion
The rough-in plumbing process may seem daunting, but it can be completed efficiently and effectively with careful planning and attention to detail. By following these key steps, you can ensure that your plumbing system is properly installed and ready for fixtures to be added.
Remember, if you need clarification on rough-in plumbing, it’s always best to consult a professional plumber. So, the next time you start a construction project or renovation, remember these key steps for a successful rough-in plumbing process.
