Troubleshooting this type of mechanism is usually quite straightforward and rarely requires replacing all of the components. How to Troubleshoot:

There are only a few push buttons and plates on the market which have serviceable bellows inside of them, the vast majority are sealed units. As such a full replacement push button or plate will likely be required if the button or plate is faulty. Blow down the pneumatic tubing that has now been disconnected from the button or plate. If the flush valve lifts and empties the cistern, then there's an issue with your push button / plate or the bellows within it. If the flush valve doesn't lift, then the bellows in the flush valve will likely need to be replaced.Depending on the model of your flushing valve or your cistern, there is an option to use a single flush or dual flush toilet button. Water saving is now an issue due to many people opting to save on their water bills. Those who have a water meter, for example, would look to utilise saving water efficiently. What is a dual flush button? A single flush toilet is often in older toilet cisterns. A one flush mechanism means that in one flush the same amount of water is flushed away. A single flush valve can use up to 12 litres of water per flush. What is a pneumatic flush button? A dual flush button features two buttons that can flush different amounts of water. The main purpose of a dual flush button is to save water. The dual flush button allows the user to control the waste water. The smaller button (half flush) delivers a smaller volume of water than the larger button (full flush). Often found in older toilet cisterns, a single flush toilet consists of just one button that flushes the same amount of water each time it is pressed. A single flush valve can use up to 12 litres of water per flush.

These valves work by squeezing air into one or two "bellows" which expand and in turn lift the flush valve and release the water in the toilet cistern. A dual flush toilet button is a combination of two buttons that can flush different amounts of water. The primary purpose of a dual flush button is to save water. The half or full flush mechanism allows the user to control the water waste, this could be useful for users who may have a water meter for example. A cable operated push button allows it to be positioned on the front, top or side of the toilet cistern. Disconnect the pneumatic tubing from the rear of the flush plate or button. The tubing usually just pushes onto one or two "spigots" on the rear of the push button or plate. Take care not to snap these off when removing. Older cisterns often have valves that require a single flush button. TYDE supply both single and dual flush buttons to fit the compatible cistern.

A pneumatic (also known as air operated) button is renowned as a more efficient and modern mechanical type flush button. As long as the pneumatic tubes are connected to the outlet valve, a pneumatic push button can be fitted. What is a cable operated button? A cable operated push button allows it to be installed on the front, top or side of the toilet cistern. Are all flushing valves compatible with single and dual flush buttons?
