No Comment Buying a dual flush toilet is one of the best ways to conserve water. Not only will this save you a lot of money annually, but it is also way more environmentally friendly than other technologies. These toilets will save you up to 75% of water without sacrificing the power and effectiveness of flushes.
However, keep in mind that there are some potential issues that could occur with dual flush toilets. Therefore, in today’s article, we are going to cover some of the top tips for most common dual flush problems.
Button Not Working
A broken button is one of the most annoying problems that can occur on a dual flush toilet. In order to fix the broken button there are a couple of simple steps you should stick to and it will be done in no time. Therefore, visit a hardware store, buy a new mechanism set, sit back, and read carefully our handy guidelines. Details are also listed in this review of dual flush toilets too.
- Shut off the water supply: Turn off the water supply under the kitchen sink using a stopcock valve. You can also stop water for the toilet only without stopping supply for the whole house if you have an isolation valve.
- Open the tank: Disconnect the refill tube after removing the lid of the tank carefully. Once you have done that, take out the old button and clean the rim of the whole, preparing it for the new button.
- Drain the tank: As you are going to have to detach the system, you should drain all the water out by flushing. After you have drained the tank you might still hear a small amount of water inside, but don’t worry, you can remove it later.
- Detach the tank: Grab a screwdriver and unscrew both screws holding the water tank attached to your wall. The two nuts holding your tank attached to the bowl are located at the bottom of the tank. After you undo them, you will be able to lift the tank away from the bowl.
- Remove the old valve: Detach your old flush valve inside the water tank. You might have to wiggle it a little bit so it slides more easily.
- Fit the new mechanism: While the toilet tank is still detached, take the new flushing mechanism and install it. As you will get a new donut gasket, you can either throw away the old one or keep it if it is still reusable.
- Reinstall the tank: After you have installed the new mechanism, it is time to put the water tank back into its place and make sure everything is fixed and steady.
- Replace the button: By unscrewing the nut at the back, you will be able to fit the new button. After connecting it to the system, you can close the tank lid.
- Turn the water supply back on: Finally, turn your water supply, or your isolation valve back on and check if everything is working properly.
Adjusting The Amount Of Water
Luckily, adjusting the level of water on dual flush toilets is quite easy. Now, depending on the type of valve, there are two different methods to use:
- Type 1 – The first one is to find the screw on top of the fill valve. Tightening it lowers the water level, while loosening the screw counterclockwise increases it.
- Type 2 – The second way to adjust the level is by pressing the sides of the lock holding the fill valve and the float valve together.
You will hear water filling the toilet tank if you start raising the level of water. You shouldn’t panic in this situation as it is quite normal. The water will stop flowing into the tank once it reaches the desired level.
Dual Flush Toilet Is Running Constantly
If your dual flush model keeps running even after the flush is over, your valve seal could be warped or worn out. Another thing that could cause this issue is dirt around the seal. Not to forget that a running toilet could also be a result of a faulty fill valve. If the fill valve isn’t working properly it could be letting water continuously flow into the tank.
Final Verdict
These were some of the most common problems that can occur with dual flush toilets. However, dual flush toilets are one of the greatest investments when it comes to bathroom appliances. It is not only environmentally friendly, but it will also save you a lot of money in the long run.
