Concealed cisterns are most commonly installed along with vanity furniture that is built in. All of the cistern is hidden with the help of the WC unit. These WC units will have to have a front panel that is removable so that they will be able to get to the cistern easily so it can be maintained. If you are having to fit a new WC unit, then the process itself can be quite overwhelming if you are not aware of the necessary steps.

Step 1: Location            

It is important that your new WC is connected to the main soil pipe. This is necessary for it to work. You will need to have it located as close to the soil pipe as possible. It is ideal for it to be directly over it.

Step 2: Prepare

Before you begin, you should make sure that you turn off the cold water. From there, you will need to completely drain the cistern and remove it from your wall. It is usually a good idea to have an assistant nearby, especially when you are removing the cistern itself. If it is in a higher area, then an assistant is very highly recommended.

Step 3: Removal

You will need a plumber’s wrench for the large nuts that need to be loosened. If these nuts happen to be corroded then it is a good idea to get a hacksaw to cut them out. You will need to take out the fixing screws or take the cylinder itself off of the support brackets.

Step 4: Cistern

If you happen to be using the old cistern with a new pan, clean the old cistern thoroughly. If the old cistern is being replaced, consider reusing the flush mechanism as well as the float valve. You will need to get a wrench to remove them.

Step 5: Pan Removal

The pan will have to be completely empty of water before it can be removed. If your pan is screwed into a wood floor, you will need to loosen the pan by removing the screws. A chisel may be necessary. With a concrete floor you will need the chisel to remove the pan. Once you have loosened the pan, rocked it and pulled it, hit the outlet with a club hammer. Be aware of the soil pipe as you do this. To prevent any type of debris, stuff rags into the soil pipe while you are working with your chisel.

Step 6: Position the Pan

You will need to be sure that the pan is aligned right with the soil pipe. With the pan in the right position you will be able to find the right connector. You will need to keep in mind the outside diameter of the outlet pipe as well as the inside diameter of the soil pipe. Also keep in mind the actual distance that is between the pipe and the outlet once the pan is in the correct place.
