How to Replace the Water Tank of a Mobile Toilet

The replacement of the water tank in a mobile toilet can be carried out according to the following steps:

I. Preparation and Safety Protection

1. Turn off the water supply: Locate the inlet valve (three-way valve) at the back or side of the toilet, and turn it clockwise until it is completely closed to cut off the water supply to the tank.
2. Empty the tank: Press the flush button to empty the residual water, or use a sponge to absorb the remaining water to prevent overflow during disassembly.
3. Safety protection: Wear rubber gloves during operation to prevent hand injuries or contact with stains.

II. Remove the Old Water Tank

1. Disconnect the inlet hose: Use a wrench or your hands to remove the metal hose connecting the angle valve and the tank, and place it in a dry place to avoid loss.
2. Remove the fixing bolts: The tank is usually fixed to the toilet with 2-3 bolts. Use a screwdriver to turn the bolts counterclockwise and remove them. If the bolts are rusty, spray lubricant to assist in disassembly. During the process, gently lift the tank to avoid scratching the toilet surface or damaging internal accessories.
3. Remove the old tank: Completely lift the old tank away from the toilet and check if the drain valve needs to be handled separately. If the drain valve needs to be removed, lift it up and turn it to the right to remove the valve body. There is a screw in the middle of the base, and use a screwdriver to tilt it to remove the base.

III. Install the New Water Tank

1. Select a matching model: The new tank must match the model and size of the toilet exactly to avoid leaks or inability to be fixed after installation.
2. Install the gasket: Purchase an appropriate gasket separately and push it into the connection between the tank and the toilet and fit it snugly to ensure sealing.
3. Fix the tank: Align the new tank with the mounting holes on the toilet, screw in the bolts and gradually tighten them to avoid excessive force on one side causing the tank to tilt.

IV. Connection and Testing

1. Connect the inlet hose: Connect one end of the hose to the angle valve and the other end to the water inlet of the tank, ensuring that the connections are tightened without looseness.
2. Restore the water supply and test: Slowly open the inlet valve, observe whether the tank fills with water normally, and press the flush button to test the drainage and water inlet functions. If a leak is found, check the gasket or the tightness of the bolts.

Precautions:

• When replacing the tank of a squat toilet, pay attention to the two screws on the wall. Lift the tank up to make the screws catch, and then pull the inlet valve rod to its maximum length before operation.
• Keep the tools dry during operation to avoid slipping or damaging the accessories.
