How to Install and Use the Concealed Cistern Dual Flush Valve
The Concealed Cistern Dual Flush Valve is the perfect solution for those who want to save water and protect the environment. This valve has two buttons: one is responsible for a complete reset, and the second for a partial one.
Valve installation
Before installing the valve, turn off the water supply and drain. To do this, close the taps on the pipes that supply water to the toilet. Then turn the drain button and hold it until all the water has drained out. After that, open the drain tank and take all the rest of the water.
The next step is to install the valve. Remove the old valve by unscrewing the nut at the bottom and pulling it out of the tank. Place the new valve in the hole and secure it with the nut. If necessary, cut the plastic tube so that it fits easily into the reservoir lid.
Valve connection
Hoses must be used to connect the valve. Attach the hoses to the valve and connect them to the water pipes. Make sure the hoses are strong and tight enough.
After installing and connecting the valve, it is necessary to check its operability. To do this, open the faucet on the pipe that supplies water to the toilet and check if water is flowing through the valve.
Valve use
The use of the Concealed Cistern Dual Flush Valve is very simple. For a full reset, you need to press the large button, and for a partial reset, press the smaller one. Thus, it is possible to save up to 50% of water.
Conclusion
Installing the Concealed Cistern Dual Flush Valve is an easy and effective way to save water in your bathroom. With it, you can significantly reduce water consumption, which will not only have a positive impact on the environment, but also save money on water bills.
