How to Do Rough-In Plumbing
The term "rough in" in relation to plumbing deals with the necessary steps that it takes to prepare the area that you are going to build or renovate in your bathroom. The technique will vary slightly depending on what item is being installed. We will use the toilet for the purpose of this article.
- Measure the area for the toilet. You will need to measure out 10 inches away from the wall to the middle of the toilet flange.
- Attach your flange. Using stainless steel nail screws, secure your toilet flange to the subfloor.
- Attach the elbow to the flange. Make sure that the elbow is at least 4 inches in diameter. Attach it to the floor flange at a 90-degree angle. Attaching at this angle will help to avoid any future leaking problems.
- Place a vent nearby. Use a vent that is at least 2 inches in diameter and place it at least 5 inches away from the floor flange.
- Install a clean out for the toilet. This is especially necessary if you are installing a toilet in the basement of a home. Most basements have concrete flooring so you will need to have a clean out to fit into the crawlspace area.
- Connect your water supply. When hooking up the cold water supply for your toilet, make sure to install it 10 inches from the ground and it needs to be put in about 5 inches on the left side of the toilet. You also need to include a compression fitting on this side as well to secure the tubing.
