Toilets include waste pipes, cisterns, flush buttons, float valves, etc. They flush out all the waste and leave your toilet bowl neat. A standard flushing system comes in different trapway shapes, such as J, U, P, and S. Choosing these systems depends on the water system and the bathroom design. Most toilets simply have a cistern/tank above the toilet bowl containing a specific amount of water. They have two devices. One device allows the rapid flow of the tank’s contents into the bowl and removes them by suction. The second device enables the inflow of water inside the cistern till the desired level is reached. The most common problem haunting toilets is a damaged or stuck flush button. While a slight slap at times could do magic but many times, it just won’t get back to its original position. You can hire a plumber to resolve your problem or try our DIY guide to replace a flush button. If you are comfortable with the latter, let’s get to work.
First, no technical task can be accomplished without the right tools. Replacing a toilet flush button does not need many tools, and all you need is a towel, a flathead screwdriver, and grips. You also need a new flushing mechanism to replace the faulty one. You can get these simple tools and supplies from any hardware store if you don’t have them at home. Once you have the tools, it’s time to get your hands wet.
Toilets can have different flushing systems. Make sure you can identify which type of system you have. For instance, dual flush units, single flush, touchless flushing, and others can be commonly found in homes around the United Kingdom. Changing the flush button should not be a problem because many of these works similarly, but if you have a unique flush system, such as a concealed cistern, you will need professional help. For the traditional ones, here is a simple DIY guide to help you replace your flush mechanism in ten simple steps.
Some intelligent plumbers install isolation valves with your toilets and washbasins. This implies that you can turn off the supply to that particular toilet without turning off the entire water supply. If that is not the case with your home, you will have to turn off the main supply. If you don’t know where it is, track your piping back to its origin, and you will find it. It is right under the kitchen sink with a W or water sign in many homes.
The next step is to open the cistern of your toilet. Lift the lid and disconnect the refilling tube. Keep the lid in a safe place as it is usually made of ceramics and can break easily. Next, Unscrew the back nut holding the flush button in place. Use a brush or a cloth to clean the hole thoroughly.
The next step is to drain all water from your flush system to empty the cistern so you can easily remove it. A little water won’t harm you and can be dealt with later.
