Why May You Want to Add a Toilet to the Existing Plumbing?

1. To Prevent Overcrowding

One of the most common reasons for wanting to add a toilet to the existing plumbing is to prevent overcrowding in the bathroom. This can be especially helpful when there are multiple people living in the same home, and it can reduce waiting times for each person’s turn in the bathroom.

2. To Increase Home Value

Adding an extra toilet to your existing plumbing can also increase the value of your home, as prospective buyers will appreciate having more than one toilet in the house. This could potentially give you a better return on investment if you ever decide to sell the house.

3. To Provide Guests with Easier Access

Having an extra toilet may make it easier for guests to access your home, as well as provide them with their own private bathroom to use while they are visiting. This can make it more comfortable for your guests and reduce the chances of any disagreements or conflicts over who gets to use the main bathroom.

4. To Increase Convenience

Having an extra toilet can also be a great way to increase convenience and make it easier for people to access the bathroom when they need to. This can be especially helpful if you have a large family or often entertain guests in your home.

5. To Save Time and Money

Adding a toilet to your existing plumbing can also save you time and money in the long run, as it eliminates the need to install an entirely new plumbing system. This can be especially beneficial if you are on a tight budget or don’t want to invest in an expensive renovation project.

Overall, adding an extra toilet to your existing plumbing is a great idea for many different reasons. It can help to prevent overcrowding, increase home value, provide guests with easier access, increase convenience, and save time and money. 

If you are considering adding a toilet to your existing plumbing, be sure to consult a professional plumber for advice on the best way to go about it. They will be able to provide you with the necessary information and guidance to ensure that the project is done properly and safely.

How to Add a Toilet to Existing Plumbing in 5 Easy Steps

Step 1: Gather All the Necessary Supplies

The very first step is to gather all the necessary supplies. This includes a toilet, wax ring, bolts, and washers. You may also need an adjustable wrench if your existing plumbing connections are too tight to remove without one.

Step 2: Turn Off the Water Supply

The next step is to turn off the water supply for the area you will be working in. This is important to avoid any water damage during the installation.

Step 3: Remove the Existing Toilet

Once the water supply has been shut off, you can now remove the existing toilet. Use an adjustable wrench to loosen and remove any existing bolts. Once all of the bolts have been removed, carefully lift up on the toilet and set it aside.

Step 4: Install the New Toilet

Step 5: Connect the Toilet to the Plumbing System

Now that the new toilet is installed, you can connect it to the existing plumbing system. Use a wrench to loosen and remove any existing connectors and then attach them to the new toilet. Once everything is connected, turn on the water supply and flush the toilet several times to make sure everything is working properly.

Once the above steps have been completed, you should now have a functioning toilet that has been successfully added to your existing plumbing system. With just a few simple steps and some basic tools, you can easily add a toilet to an existing plumbing system. Good luck and happy plumbing!

Some Additional Tips to Add a Toilet to Existing Plumbing

1. Do Not Make any More Concrete Cuts

After the old toilet is out of the way, it is important to avoid making additional cuts beyond those that are necessary for the new installation. The more concrete cuts you make, the weaker your foundation becomes, and it could create future plumbing issues.

2. Use a Toilet Flange Extender for Existing Pipes

If there is an existing drain pipe that is too low, it can be raised by using a toilet flange extender. This will ensure the drain line connects properly to the new toilet without having to cut and replace the old pipe.

3. Check for Leaks

Once the new toilet has been installed, it’s important to check for leaks and ensure the connection is secure. This should be done before the flooring around it is replaced. If any water is leaking from the connections, tighten them further or call a plumber if necessary.

4. Use a Toilet Wax Ring

For a secure seal between your new toilet and the drain pipe, use a toilet wax ring. This will ensure that there is a tight seal and that no water escapes from the connection.

5. Add a Shut-Off Valve

Another important step in installing a new toilet is to add a shut-off valve. This will allow you to turn off the water supply for the toilet without having to shut off the entire house. This can also be helpful in the event of an emergency or accident.

6. Test the Flush

Once everything is installed and secure, it’s important to test the flush. This will help ensure that the toilet is working correctly and that there are no leaks or other problems before you close up the project.

Following these steps will ensure that your new toilet is installed properly and securely connected to existing plumbing. The process may seem intimidating, but with the right supplies, it’s a relatively simple task that can be done by DIYers. With the help of this article, you can now confidently add a toilet to existing plumbing.  Good luck!
