07/02/2025 | Hawkrown
The water level in most toilets is controlled by the tank. Sometimes, the water level can be too high or too low, which may lead to unsatisfactory usage. Here's how to adjust the water level in the toilet tank.
To adjust the water level in the toilet tank:
First, remove the toilet lid, then take out the fill valve component. Turn the adjustment knob on the fill valve to the "OPEN" position. By pulling the fill valve body, you can raise or lower the fill valve.
You can also adjust the adjustment rod inside the tank to raise or lower the water level. Turning the adjustment rod clockwise raises the float and increases the water level in the tank. Conversely, turning it counterclockwise lowers the water level.
Move the adjustment cup up and down to adjust the small flush water volume; the lower the position, the larger the flush volume, and vice versa.
If you want to save water on a daily basis, you can place a filled beer bottle in the tank. This effectively reduces the water capacity, helping to save water.
Considerations for Installing a Toilet:
1、Determine Installation Position and Drill Holes
Align the floor drain pipe with the toilet's bottom drainage outlet and mark the positions for fixing holes. Use a hammer drill to create holes about 5 cm deep. Install the toilet base by inserting expansion bolts into the drilled holes, placing the expansion bolts in, and tightening the nuts. Connect the drainage outlet to the drain pipe and seal it.
2、Install the Tank
Based on the installation height of the tank and the location of the tank holes, drill holes at the fixing position and insert steel expansion bolts to secure the tank. Make sure the back wall holes fit onto the expansion bolts, then place nylon washers and tighten nuts. Connect the pipe between the tank and the toilet base, as well as the inlet pipe to the bottom of the tank. An angle valve should be added at the inlet pipe connection.
