How to Move Toilet Drain

For example, if your waste line diameter is three inches, your toilet must be no closer than six feet from the stack. The toilet must be located at least 10 feet away from a waste line that has a diameter of 4-inches. Check out this article to learn more about moving your toilet and the distance between the toilet and stack.

Distance Between The Toilet And Main Stack

It depends on the diameter of the waste line how far the toilet is from the main stack. The toilet should not be more than six feet from the stack if the waste line has a 3-inch diameter. However, if the waste line is 4-inches wide, the toilet should not be farther away from the stack than 10-feet.

The diameter of the waste line changes the slope of the waistline, thus affecting the distance between the toilet and stack. Pipe drops should always be between 14 and 16 inches per horizontal foot. To maintain the proper slope, the toilet should be placed far away from the stack, the larger the diameter.

How to move a toilet

The pipes that supply water to the toilet, along with the fixture, need to be moved whenever a toilet is moved. Fixtures are the easiest parts to move; however, water supply lines and drainage lines are also tricky.

The toilet drain needs to be moved

In the bathroom, there are several drainage pipes. The normal diameter is three to four inches, and the tubes crisscross between joists and other pipes. Waste must be drained correctly through drainage pipes that are controlled by gravity.

It’s recommended to drop drainage pipes by 14.5 inches vertically for every foot horizontally. Because of this, it is necessary for the toilet to be located a sufficient distance from the stack in order to maintain this slope rate. Waste lines with diameters of 3 inches should be fitted The stack should be as far as possible from toilets with a 3-inch diameter. Toilets should not be closer than 10 feet from the stack if the diameter of the waste line is 4 inches.

Providing Water from a Moving Source

You can move the water supply once the toilet drain has been moved. Since the toilet does not have to be close to the main stack, this aspect is easier. It is easier to move water supply pipes since they are smaller. A nearby toilet line could be connected to the relocated supply line.

Toilet Moving Instructions 

Toilets are notoriously difficult to move. The project should only be undertaken by someone who has experience renovating toilets and installing toilets. When it comes to renovating your bathroom, hiring a professional is an excellent option if you are not comfortable doing the work yourself. To help you move your toilet, here are the steps to take.

Toilets should be removed. Avoid breaking or chipping the fixture if you are reusing the toilet. It is better to dispose of your old toilet responsibly if you are not planning to reuse it. Once you’ve cleared the drainpipe, place a rag inside it to prevent tools from falling down the pipe and gas from rising.

1. Gain access to the site

To reach these drain lines, you will have to dismantle the bathroom floor. A drainage line can be accessed from either above or below. The subfloor can be accessed from above by cutting out about an eighth inch with a saw blade. The drywall ceiling must be demolished from below to access from above.

2. Remove the Flange

Take the toilet flange off the drainpipe by unscrewing it with a screwdriver or drill driver. In instances where the toilet flange has been sealed down, you may need a hammer or reciprocating saw.

3. Remove the bend in the toilet

The previous bend in the toilet should be cut away with a reciprocating saw. The waste vent stack should be as near to the water heater as possible.

4. Determine the location of the new drain

Place the drain in its proper location. To be safe, the length of the drain should exceed 15-inches from the center to any sidewalls, such as the bathtub or shower.

5. Install new drainage

Connect the new drain to the waste vent stack at the new toilet location. Place the toilet in the correct position relative to the stack. It is recommended to place the toilet at least six feet from the stack if the pipe has a diameter of three inches.

The distance between the toilet and wall stack should be no greater than 10 feet in the same case if the waste line has a diameter of 4 inches.

Where you severed the old drain, install a wye fitting. You must bend the pipe 90 degrees to ensure that it reaches the toilet. Use appropriate glue to join the pieces. When you glue, make sure the lines incline at a slope of 13.5 inches per vertical foot toward the stack.

6. Connect the stub-out hose to the drain

A drain stub-out must be installed. The new drain should be glued with a 90-degree bend. You should also place a 6-inch pipe through the ground into the upward-facing socket.

7. Connect the water pipes

Connect the pipe with the water supply via the joists. Tubing can be connected to copper pipes in a number of ways. Find the technique that suits you best. When a pipe emerges through a wall, install a copper elbow with a flange and stud nails.

8. Flange installation

Subfloors should be replaced and drainpipes should be cut flush with the finished floor. Overlay the flooring with the toilet closet flange.

9. Setting up the toilet

On top of the toilet closet, mount the toilet. The water supply should be connected to the fixture, and it should be turned on. Further Reading.
