Capping a toilet drain may seem like an overwhelming task, but it can be done easily with some basic knowledge and the right tools. Whether you’re renovating a bathroom or removing an old toilet, capping the drain can be a necessary step in the process. With this step-by-step guide, DIYers can learn how to cap a toilet drain and complete the job with confidence.
First, it’s important to understand why capping a toilet drain is necessary. If you’re removing an old toilet or relocating the fixture, capping the drain will prevent any sewer gases from entering your home. Additionally, capping the drain is necessary if you’re converting a bathroom into a different type of space, such as a laundry room or a storage area. With the right tools and a bit of patience, capping a toilet drain can be done quickly and easily.
Gather Your Tools and Materials
Gathering your tools and materials is important to begin any plumbing project. For capping a toilet drain, you will need basic plumbing tools such as pliers, a hacksaw, and a screwdriver. Additionally, you will require a PVC cap that fits the size of the toilet drain and PVC primer and glue to create a secure seal.
A hacksaw will be used to remove any existing pipe that sits above the toilet flange, while the pliers are useful for taking hold of any stubborn bolts that might otherwise be difficult to remove. Finally, the PVC primer and glue will create a strong and durable bond between the pipe and cap. By having all the necessary tools and materials at hand, you can work with greater comfort and efficiency, ensuring the success of your project.
Prepare the Toilet for Capping
Before capping the toilet drain, there are a few things that you need to prepare for. First, you need to turn off the water supply valve that is located behind the toilet. You can do this by turning the valve clockwise until it stops. After that, flush the toilet to get rid of any remaining water in the tank and bowl.
Next, remove the mounting bolts that secure the toilet to the floor. These bolts are usually located at the base of the toilet and can be easily removed with a wrench or pliers. Once you have removed the mounting bolts, lift the toilet off the floor and tip it over onto its side. Place a towel or old rag underneath to catch any water that may still be inside the toilet. With the toilet now upside down, you can proceed to cap the drain using the appropriate materials and tools.

Remove the Old Toilet Flange
The toilet flange is a fitting that connects the toilet bowl to the drain pipe in the floor. If you’re installing new flooring and want to raise the toilet, or if the flange is cracked or corroded, you may need to remove the old flange. Follow this step-by-step guide to remove the old toilet flange and install a new one:
First, turn off the water supply to the toilet and flush it to remove any remaining water in the bowl and tank. Next, use a wrench to loosen and remove the nuts securing the toilet to the flange. Once the toilet is free, carefully lift it off the floor and set it aside. Then, use a screwdriver to remove the screws that hold the flange in place. The flange may be glued or sealed to the drain pipe, so you may need to use a putty knife or scraper to loosen it before removing it completely. To ensure a proper fit, clean the drain pipe thoroughly before installing the new flange.
Insert the Cap into the Drain
Before inserting the cap into the drain, make sure that the surface is clean and dry. The cap should also be the correct size for your toilet drain. You can choose between different types of caps, such as rubber plugs or plastic caps, depending on your preference.
To insert the cap, simply place it over the open drain and push it down firmly until it is snugly in place. You can also apply some pressure to ensure that the cap is securely in place. Once you have inserted the cap, test it by running water into the toilet bowl. If the cap is properly inserted, the water should not drain out.
It is essential to properly cap your toilet drain to prevent unwanted debris from entering your plumbing system. By following these easy steps, you can cap your toilet drain easily and efficiently. However, if you are unsure or uncomfortable with doing the job yourself, it is always best to consult a plumbing professional.

Secure the Cap in Place
After placing the cap over the toilet drain, it’s important to secure it in place to prevent any leaks or damage. The first step is to apply a layer of plumber’s putty around the bottom edge of the cap to create a tight seal. Press the cap firmly onto the toilet flange, ensuring that it is centered and level. Use a wrench to tighten the bolts or screws that hold the cap in place.
Once the cap is secure, turn on the water supply and flush the toilet to check for any leaks. If there are no leaks, install the toilet bowl and attach it to the flange using the appropriate bolts or screws. Your newly capped toilet should be ready to use, but be sure to inspect it regularly for any signs of wear or damage. With a little bit of patience and the right tools, you can successfully cap your toilet drain and avoid costly plumbing repairs in the future.
Test the Plumbing System
After successfully capping off the toilet drain, it’s important to test the plumbing system to ensure that everything is working as it should. The first thing you should do is turn the water back on and check for leaks. Also, make sure that the water flow is adequate and that the toilet flushes properly without any signs of blockages or slow draining.
After you’re satisfied with the water flow and drainage, it’s important to check the toilet’s venting system. A properly vented toilet ensures that there are no unpleasant odors or harmful gases emitted into your home. To check the venting system, flush the toilet and listen for any gurgling or bubbling sounds in your sinks or other plumbing fixtures. This indicates that there’s a blockage in the venting system that must be cleared. Lastly, be sure to clean up any debris or tools from the job and dispose of them properly.

Finish Up and Reinstall the Toilet.
Once you have capped the toilet drain, it’s time to finish up and reinstall the toilet. Start by removing the towels or rags you had placed over the drain and give the area a quick clean up. Examine the cap to make sure it’s secure and there are no leaks. Run some water down the drain to check for any leakage. If everything looks good, proceed with reinstalling the toilet.
Start by placing the wax ring on the flange and then carefully lower the toilet over the drain. Gently push down on the toilet to ensure the wax ring seals properly. Once the toilet is in place, reconnect the water supply line and tighten the nuts. Finally, install the toilet seat and lid. Don’t forget to flush the toilet a couple of times to make sure everything is working smoothly, and you’re done! By following this simple guide, you’ll be able to cap your toilet drain without any trouble and save a lot of money on plumbing services.
