It’s not that difficult all you just need to do is to undo the back nut. Clean the rim of the hole and now it’s ready for the new button. Be gentle with the lid.

Draining of Water:

Before you proceed any further, make sure to flush down the system and you will be able to clear out the cistern. It will avoid the risk of flooding everything in the bathroom. You can flush out the system easily depending upon the nature of the flush mechanism. If there is any water left, don’t worry about it.

Pull out the Cistern:

Take the screwdriver and carefully take out the screws holding the tank to the wall. Remove the wing nuts underneath the cistern and the pipes that go into the tank.

Remove the old Flush Valve:

You will find a rubber gasket, right at the base of the cistern. Use grips to remove the metal clamp and check if the rubber washer is still in good condition. If the condition of the rubber washer is good, you can reuse it. Remove the flush valve from the tank and then give it a wiggle to slide around the hole.

Install the New Flushing Mechanism:

Installation of the new flushing mechanism can be a pain to fit. Pull out the washer and remove the nut by hand, then move the seal up. Add the new valve through the cistern and hold it in place. Now put back the rubber gasket.

Put the Cistern back:

Now it’s time to reserve the process of taking the cistern off the wall and putting it all back altogether. Start with the bolts, then put the cistern back in place. Tighten the wing nut to hold the cistern to the toilet bowl. Use a screwdriver to tighten the screws and make sure that the cistern is ready.

Adjust the Flush valve:

Set up the flush valve to a position that allows the floats to move up and down without getting stuck. Run the test, once the water supply is back on.

Change the Flush Button:

This is the easiest part; all you need to do is unscrew the nut at the back. Fit the button before tightening, then connect the button to the rest of the toilet system and add the lid.

Turn On the Water:

Finally, now it’s time to put all the toilet’s assembly back into the water supply. Be very careful, when it comes to stone made equipment, you don’t want to break anything. Flush the toilet to check if the button is working or not. Look for any kind of leaks to make sure, if you have assembled the toilet properly.
