Toilet Tank Installation Process

This section elaborates on the method of installing a toilet tank. We will explicitly discuss all the installation steps one by one.

Disconnect the Water Supply

The first step to any plumbing work is disconnecting the water supply through the valve of that specific plumbing stationary where you have to work. In this case, we have to work on the toilet tank, so we should locate and turn off the water supply valve to cut the toilet’s water supply. If you do not find an isolating valve for the bathroom, turn off the water supply from the main to make sure that the plumbing work is not disturbed.

Empty the Toilet Tank

After you have turned off the input water supply, drain the water in the toilet tank. Press the button to flush out the water, and use a rag and sponge to dry the tank.

Disconnect the Supply Hose

The toilet tank stores the water from a water supply line that connects to the bottom of the tank. Once you press the button, the toilet tank flushes out the water and then restores the new incoming supply.

Since the input water supply is cut off and there is no water in the toilet tank, removing the input water supply line is safe. You need to disconnect the supply hose from the bottom of the tank. You can remove the hose using your hands or with the help of a wrench.

Locate and Extract the Bolts

The toilet tank is typically connected to the cistern with the help of nut bolts. You need to locate these nuts and hold them with pliers while you loosen the bolt heads from inside the tank. In this way, the nuts will also loosen, and you can easily remove the nut bolts. Repeat the action on both sides of the cistern.

Remove the Old Toilet Tank

Since the nuts and bolts are loosened enough to remove the unit, it’s time to move ahead. It would help if you lifted the tank with both hands to avoid any cracks in the tank. Remove the tank safely from the cistern and place it safely. The removal of the old tank is to replace it with a new one, so we now look at the process of installing a toilet tank.

Get a New tank of the Suitable Size

If you are replacing an old toilet tank, purchase a new one of the same size. However, if you install a new one, you should measure the size and compatibility of the tank to the bowl.

Since the bowls also come in different standard sizes, finding a tank compatible with the bowl is not a complicated task. You will find a suitable tank for your toilet without much effort.

How to Install Toilet Tank to Bowl Bolts?

Installing a toilet tank is not a big deal. First, you will place washers on all the bolts of the tank. Usually, we prefer rubber washers over metallic ones. Press the washer tightly at the head of the bolt so that it creates a tight seal to prevent potential leaks. If you don’t have a washer, you can use large rubber items that fit into holes at the bottom of your tank.

Now lift the tank and adjust it over the cistern in the correct position. Be sure to place the bolts in a suitable space to fix the tank properly. Carefully hold the tank in this process to avoid damage to the new unit.

Screw the Nuts

Now place nuts on each bolt and tighten them to fix the toilet tank on the cistern. You may need to use pliers to correctly tighten the nuts and station the tank on the toilet assembly.

Turn on the Water Supply and Check for the Leakages

Now turn on the water supply and test the system. If there is any leakage, fix it, or else you have successfully completed the toilet tank installation.


It is primary plumbing work to install a toilet tank; you do not need to call a plumber. If you have confidence in your basic plumbing skills, you can easily replace the old toilet tank with a new one. You need to follow the step-by-step guide to complete the process effectively.
