How can I replace a toilet flange?

1. Loosen the 2 nuts that are located on each side of the toilet. Place them in a safe location, because you will need them to remount the toilet.2. Lift the toilet. Set it in a place where the rest of the water can drain from it, such as a shower or bathtub.3. Clean the wax from the flange seal, and then remove the screws that attach it to the floor.4. Measure the pipe that comes out of the floor so that you purchase the correct size. You will need to buy a new flange, a new section of pipe with the same diameter as the old pipe, a pipe coupling, a new wax ring and PVC glue if you do not have any.5. Cut off the flange at the red line. This can be done, from inside the pipe, using a Dremel tool with a reinforced disk for cutting.

What size went is needed on the toilet drain?

2" VENT. Many codes say the vent can be 1/2 the size of the pipe being served but in no case less then 11/2" and considering a lead bend (toilet drain) can be 3" and the new fixtures have 1.6 GPF in lieu of the 3.5 GPF a 11/2 vent pipe is fine


Can you connect a new toilet to an older toilet vent?

Yes if the vent pipe is 4" and vertical by code and there is nothing connected between your toilet tee and where you would connect your new toilet tee. If not worried about codes then yes you can connect to a 3" vent line if no other vent lines are connected down stream. If you have a vent pipe that is less then 3" and or you have other vents connected between your old toilet tee and your new toilet tee then NO you can not connect a new tee for your toilet.


How high does the toilet overflow pipe need to be?

Kits are available to make sure the toilet flange is level with the new floor. These kits are adjustable because of the differences in thickness of flooring and material, any subflooring laid down, grout, infloor heating etc. . Ideally, you want to seat the toilet on the wax gasket, and attach the mounting bolts, and have the toilet flat on the finished floor. These kits are easy to find and use.


Is the drain pipe the same for a new toilet in a 40 year old house?

Uh huh


Is it due to the size of the toilet or just the bad installation if the water tank of the new toilet is about 2 inches away from the wall?

Probably it is due to the size of the toilet tank. If the toilet is a low flow, or under 2 gallons per flush, the tank will be considerably smaller than an older toilet tank, which might hold as much as 25 gallons. The only critical thing in istalling a toilet is if the drain pipe lines up with the drain opening. Unless you move the toilet drain, the new toilet is going to sit in the same place. If you have a gap between the wall and the tank, you might want to put a block of wood or something to help anchor the tank. Newer tanks are smaller due to the reduced water need with the current flushing technology.

Tighten each bolt with an adjustable wrench. Be very careful not to over tighten the bolts.
