Summary: Learn how to remove an old toilet, remove a pan with a down waste outlet, remove a pan with a horizontal waste outlet, install a toilet with a down waste outlet, fit a new toilet cistern and fit a toilet seat.
There may come a time when you want to change your bathroom suite, which will inevitably involve replacing the old toilet. The method you employ to do this will depend on the type of toilet you are installing but for the purpose of this project we will look at fitting a new close coupled toilet (see diagram), as this is the most common toilet in use today.
How you remove the old toilet depends on whether the pan has a horizontal waste outlet or a down waste outlet cemented to the floor. But first you will need to remove the old cistern.
Remove the mortar around the collar of the waste pipe.
If your supply pipe to the toilet cistern does not already have a stop valve connected, use this opportunity to install one to allow you to cut off the water to the toilet in the future without having to turn off the mains supply.
Whether you are fitting a toilet with a down or a horizontal waste pipe it is advisable to connect the pan with the cistern first.
Follow the same method to install a toilet with a horizontal waste pipe, but insert a straight pan connector into the waste outlet in the wall instead of the floor.
Connect a flexible connector to the cold-water supply pipe at one end and the cistern at the other.
