Plumbing is an essential step in installing a new toilet in the bathroom. While there are many reasons why you want to get a new toilet installed, what matters here is the fact that plumbing is something that you can never skip.

The own waste outlet of the toilet is the start of any toilet waste system while the soil stack is the main pipe. The stack is a vertical pipe with a length of 3 to 4 inches. This pipe drops into the sewer and this is connected to a pipe measuring 2 inches rising through the roof to offer venting.

Three basic fittings are required for connecting the new toilet to the existing stack. The first fitting holds down and seals the toilet. The second one directs the flow of water to the stack while the third one is what ties the new toilet to the stack.

Here are the steps to do plumbing for a toilet:

  1. Identify the location of the new toilet’s hole. Use a tape measure to measure from the walls. The hole must be 12 inches for most models starting from one of the side walls and the back wall.
  2. Use a reciprocating saw for cutting out the hole. The hole must have a diameter of 3 inches to have enough room for the 3-inch waste pipes for most toilets. However, the toilet waste line must have a diameter of 4 inches depending on your toilet model as well as the distance between the soil stack and the toilet. When unsure, it is best to consult a plumber.
  3. For installing a toilet flange, push the pipe through floor and set the plastic or metal ring on the subfloor. The upper ring must be flush with the finished floor’s surface. Bolt or screw the flange into the subfloor.
  4. A PVC closet bend must be dry fitted onto the flange pipe extending through the floor. This closet bend is the 90-degree wide-sweep elbow used for installing toilets.
  5. Measure the distance between the soil sack and closet bend’s stack and use tape measure and spirit level to form a mark on the stack to create a slope on the connected waste pipe going to the stack of ¼ inch per foot. For instance, if there is a 6-feet distance between the stack and the bend, the mark must be 1 ½ inches below the upper portion of the bend outlet.
  6. Use a handsaw for cutting through the stack following the mark. The sanitary fee should now be inserted and the inlet should face the toilet. There is a sweep inlet in a sanitary tee instead of a straight one. This sweep must face downwards.
  7. Using the handsaw again, cut the length of the 3-inch PVC pipe equivalent to the distance between the tee inlet and bend outlet with additional 2 inches. This must be dry fitted between the tee and the bend.
  8. Use dry fitting to disassemble all the assembled parts and assemble them again using PVC cement when you are finally sure that all parts fit. The waste line should be glued in last and double-check the slope before doing so.
