One, how to install the toilet flush tank

1. Before installing the sink, measure and mark the specific installation height using a measuring tape, and then note it down. Additionally, pre-install the drain pipe at a suitable location on the wall and check the distance from the pipe opening to the floor.

2. once the location is determined, remove the plug from the drainage pipe and wrap tape around the valve, then install the valve into the inlet pipe on the wall to enable on/off control of the water supply.

3、Remove the drain tank accessories and measure the hole size on the wall. After drilling the holes, install the screws and secure the pipe for easy installation of the tank.

4、Mount the water tank and connect the drain pipe properly. once installed, tighten the screws using a screwdriver.

5、Attach one end of the hose to the valve and the other end to the bottom of the water tank. Connect the inlet pipe and apply sealant at the interface to effectively prevent leakage.

6. Finally, open the valve for testing. If any issues arise during use, please address them promptly.

Two. What should be noted when installing the flush tank?

1、During the installation of valves and water inlets, please avoid applying excessive force, as this may damage the threads and lead to leakage in the flushing tank.

2、The distance between the water level in the washing tank and the overflow outlet should be less than 38 mm. The water level in the inlet valve must exceed the overflow outlet, and the distance should not be less than 25 mm. This requires precise measurement of the washing tank installation height.

3、The water pressure should be between 0.14 and 0.55 MPa to achieve excellent flushing.

4、When installing a new water tank, pay attention to whether the new tank's location is similar to the original. If there is a significant difference, the wall-mounted fixtures must be relocated.
