How to Repair Mobile Toilets in Prefab Houses

The repair of mobile toilets in prefab houses requires functional maintenance tailored to specific fault types. Common issues and solutions are as follows:

I. Common Faults and Repair Methods

1. Flushing System Failure
   Abnormal flushing is often caused by insufficient water pump pressure, solenoid valve malfunction, or sensor errors. If the water pump pressure is insufficient, check whether the power connection is normal and clean the inlet filter. If the solenoid valve is stuck, disassemble and clean it or replace it with a new valve body. Sensor errors can be resolved by adjusting sensitivity or replacing the battery; if still ineffective, replace the sensor.

2. Sewage Pipe Blockage
   Blockages are usually caused by improper use leading to debris accumulation. Use professional unclogging equipment (such as pipe springs or high-pressure water guns) to clean the pipes. If the blockage is deep, disassemble the pipe connections for thorough unclogging and check if the sewage valve is damaged.

3. Door Lock or Lighting System Failure
   For a damaged door lock, replace the lock core or lock body according to the model. For a lighting system failure, first check if the power circuit is poorly connected; if the bulb is burnt out, replace it with a bulb of the same specification; if the circuit board is faulty, replace the entire unit.

4. Box Structure Deformation
   Frequent handling or uneven foundations may cause box deformation. Use structural correction tools (such as hydraulic jacks or specialized clamps) to adjust the deformed parts and reinforce the connections. If the deformation is severe, weld reinforcement or replace the damaged panels.

II. Hierarchical Implementation of Repair Work

1. Daily Inspection
   Before and after each use, check whether the flushing, sewage, door lock, and lighting functions are normal, clean any residual debris, and ensure there are no leaks or odors.

2. Regular Maintenance
   Schedule maintenance based on the rental duration, including testing water pump pressure and solenoid valve sensitivity, replacing filters, batteries, and other consumables, and lubricating mechanical parts such as door lock hinges.

3. Fault Repair
   Respond immediately upon receiving a problem report, bring corresponding spare parts (such as solenoid valves and sensors) and tools (such as pipe unclogging equipment and circuit testers) to the site for repair, ensuring quick restoration of use.

III. Repair Technical Requirements
Repair personnel must master water and circuit principles, box structure characteristics, and environmental protection treatment techniques, and be proficient in using welding equipment and structural correction tools. Spare parts inventory should cover different brands and models to ensure compatibility.
