How to Open the Water Tank of a Mobile Toilet

The method for opening the water tank of a mobile toilet varies depending on the type of water tank. It is necessary to select the corresponding operation steps according to the specific structure. It is recommended to turn off the water source and take protective measures before operation.

I. Button-Type Water Tank Lift the top cover of the water tank directly upwards without tools. If it is a ceramic cover, due to its relatively large weight (about 3-5 kilograms), it is recommended to operate with both hands to prevent slipping. Some models have buckles that need to be lightly pressed before lifting. If the buckle is stuck, it can be softened by heating with a hairdryer for 3 minutes, or rubber gloves can be used to increase friction for assistance in opening.

II. Wrench-Type Water Tank

1. Metal wrench: Unscrew the fixing nut counterclockwise and then lift it up.
2. Plastic wrench: Pull it directly upwards.
3. Old-style cast iron water tank: If it is stuck due to scale buildup, gently tap the edge to loosen it before lifting.
4. Embedded water tank: Use a Phillips screwdriver to remove the screws around the cover (if the screws are rusty, spray WD-40 lubricant and wait for 5 minutes before operating).
5. Water tank sealed with sealant: Use a utility knife to cut along the edge of the sealant. Wear gloves during operation to prevent scratches from burrs.

III. Split-Type Water Tank (Water tank separated from the toilet)

1. Locate the cover: Most are located directly above the water tank. Observe whether there are screws or buckles fixing it.
2. Release the fixing:
   • Screw fixing: Use a flashlight to observe and then unscrew it counterclockwise with a screwdriver.
   • Buckle fixing: Press the cover with the palm of your hand and slide it horizontally towards the back of the water tank.
3. Lift the cover: Hold the bottom with both hands and lift it upwards, paying attention to the weight (3-5 kilograms).

IV. Integrated-Type Water Tank (Integrated design)

1. Confirm the type of flush button:
   • Circular single button: Rotate it 90 degrees counterclockwise to disassemble.
   • Double buttons: Insert a flat-head screwdriver into the gap and gently pry up the upper cover.
2. After removing the buttons, remove the fixing screws and lift the bottom of the water tank cover upwards at an angle of about 15 degrees to unlock the buckles.

V. Special-Type Water Tanks

1. New-style press-type: Press both sides of the recess evenly with both hands and lift upwards after hearing a 'click' sound.
2. Squat toilet water tank: Press both buttons simultaneously with two fingers, and the cover will pop up automatically. For smart models, you need to enable maintenance mode through the APP or press and hold the 'Flush + Energy Saving' button for 5 seconds.

Precautions

1. Turn off the main water valve before operation (rotate the angle valve behind the toilet or on the wall to a vertical position). For smart toilets, cut off the power or enter maintenance mode.
2. If the above methods are not applicable, it is recommended to consult the product manual or contact professional maintenance personnel to avoid damage caused by forced disassembly.
