How to Disassemble the Water Tank of a Mobile Toilet

The steps for disassembling the water tank of a mobile toilet vary depending on the type of water tank (toilet tank or squat toilet tank). The details are as follows:

I. Steps for Disassembling a Toilet Tank

1. Turn off the water supply
   Locate the main water supply valve in the bathroom (usually located behind the tank or on the wall). Turn the valve handle counterclockwise to the farthest end to completely cut off the water flow and prevent continuous water inflow during disassembly.

2. Drain the water from the tank
   Press and hold the flush lever or press the lever on the side of the toilet to drain the remaining water from the tank through flushing. If there is still water at the bottom, use a sponge or absorbent cloth to thoroughly dry it to prevent water from overflowing during subsequent operations.

3. Disconnect the water inlet pipe
   A metal or plastic water inlet pipe is usually connected to the bottom of the tank. Use your hand to turn the water inlet pipe connection counterclockwise to loosen it. If it is difficult to turn, you can use pliers or an adjustable wrench to assist, but control the force to avoid damaging the threads. After the connection is loosened, slowly pull out the water inlet pipe and place a towel or bucket below to catch any residual water that may overflow.

4. Loosen the fixing bolts
   The tank is fixed to the toilet bowl with 2-3 bolts. Insert a screwdriver into the inside of the tank, find the bolt head and turn it counterclockwise. At the same time, use your other hand to hold the nut under the tank. After the bolt is completely loosened, take out the bolt and nut together.

5. Lift the tank
   Hold both sides of the tank with your hands and lift it vertically upwards to separate it from the toilet bowl. Keep the operation steady to avoid the tank tilting and scratching the surface of the toilet or the floor. After separation, place the tank on a soft towel or foam pad to prevent bumps.

II. Steps for Disassembling a Squat Toilet Tank

1. Close the three-way valve and drain the water
   Locate the three-way valve for the water supply to the tank (usually located at the connection of the wall or floor pipes). After closing the valve, drain the water from the tank through flushing. If there is residual water at the bottom, use an absorbent tool to clean it up.

2. Open the tank cover
   The cover of a squat toilet tank is usually designed with snap-on fasteners. Simply lift it up gently to remove it. If the cover is tight, check the edges for fixing screws and loosen them with a screwdriver before disassembly.

3. Adjust the position of the tank
   The tank is usually fixed to the wall with two screws. Hold both sides of the tank with your hands and lift it slightly upwards until the screws catch the bottom of the tank, creating operating space for unscrewing the main water pipe later.

4. Disconnect the main water pipe
   The main water pipe connects the bottom of the tank to the water supply system. Use a wrench to turn the water pipe connection counterclockwise to loosen it. After taking out the water pipe, the tank can be completely separated from the wall fixing structure.

Precautions: During disassembly, if you encounter stubborn screws or rusted parts, you can spray a small amount of lubricant (such as WD-40) to assist in disassembly. It is recommended to wear gloves during operation to avoid scratches or contact with residual sewage.
