Basics for toilet installation

Understanding how to install a toilet isn't difficult at all, but it is really important to get a good seal. After the flooring is done we will attach the toilet flange to the plumbing wastepipe.

As part of the plumbing you’ll see the toilet flange with two bolts sticking out of the floor where the toilet will go.

Before you put the toilet onto the flange, you will need to put a wax ring onto the bottom of the toilet. You can get wax rings and sleeves at any plumbing store.

After you apply the wax ring and sleeve as shown in the illustration, you can then place the toilet on to the flange bolts. You should push down on the toilet so the wax ring makes a good seal.

Next you will put the washers and nuts on and secure the toilet. Over tightening can break the porcelain, so be careful to get it just right.

Next you will put on the trim caps and you are done with the toilet bowl. Next, you’ll put the tank on. You need to make sure that the holes line up before screwing them in place. The flush valve and bolts will fit into the holes.

These illustrations show how the tank will fit on to the toilet and where the screws need to be secured.

The connecting bolts will be tightened to make the tank secure. Next is the connection of the waterline and the toilet seat.

Once the toilet is secure you will want to run a bead of silicone around the base of the toilet. I discourage the use of bathroom caulk because it starts to crack after just a few months.
