If you live in a small, cramped home or apartment, connecting two toilets to a single soil pipe might be a clever solution. You can save time, space, and money on plumbing bills by connecting two toilets to a single soil pipe.
But how to connect two toilets to one soil pipe? To connect two toilets to a single soil pipe, you must first attach a tee fitting to an existing soil pipe and connect the waste pipes from each toilet to the tee fitting.
Check out the article below for a step-by-step guide on how to connect two toilets to one soil pipe.
Connecting Two Toilets To One Soil Pipe: A Step-by-step Instructions-
You can connect two toilets using one soil pipe if they are on the same side in your house. It will allow the waste from both toilets to flow into the same soil pipe. Thus, it will be carried out of the building to the main sewer line or septic system.
You should make sure the pipes are installed in the right order and at the right size to prevent blockage.
The following instructions will give you a proper idea of how to connect two toilets to a single soil pipe:
The tools you will need for this process
- PVC soil pipe
- Saw or pipe cutter
- Access plug
- T-shaped pipe fitting
- Rubber joints
- Measuring tape
- PVC cement
Step 1: First, turn off the water supply of the existing toilet. After that, unbolt the soil pipe from the flange, remove it, and then drain the pipes.
Step 2: You need to plan ahead of time the location of the second toilet. Then use a marker to mark the location of the new flange. The flange should be approximately 4 inches.
Step 3: Measure the length of the soil pipe that needs to be removed. Then, use a pipe cutter to remove a portion of the soil pipe to make a place for the T-shaped pipe fitting.
You should make sure to keep the soil pipe slightly longer than the tee fitting to connect the tee fitting and the soil pipe securely.
Step 4: Once the pipes have been cut, you must use sandpaper to smooth down any uneven or rough edges.
Step 5: Now, the T-shaped pipe fitting must be installed onto the soil pipe by joining the cut ends of the soil pipe to its branches. To keep the connection secure, use a pipe wrench to tighten the nuts on the couplings.
Step 6: Attach a section of the waste pipe onto each branch of the tee fitting.
Step 7: Install the new flange for the second toilet. You need to make sure the new flange for the second toilet is parallel to the ground and firmly fastened to the floor.
Step 8: At this point, use a rubber joint to connect the waste pipe from the second toilet to the new flange.
Step 9: The waste pipe from the current toilet should then be connected to the tee fitting using a rubber coupling.
Step 10: All of the connections, including the rubber joints and the tee fitting, should be glued together with PVC cement.
Step 11: The next step is to turn on the water supply to the toilets, flush both of them to check for leaks, and look for any water leaks at the connections.
Step 12: When you are certain there are no leaks, use the bolts and nuts to secure the toilets to the flanges.
