Mobile Public Toilet Maintenance Plan

The maintenance plan for mobile public toilets needs to be comprehensively formulated from aspects such as maintenance principles, content, procedures, and handling of common faults to ensure the safety, hygiene, and efficient operation of the facilities.

I. Maintenance Principles

1. Prevention First, Combination of Prevention and Treatment: Reduce the occurrence of faults and extend the service life of equipment through regular inspections and maintenance.
2. Timeliness: Handle faults immediately upon discovery to prevent minor issues from expanding and affecting usage.
3. Economy: Under the premise of ensuring quality, prioritize low-cost maintenance solutions.
4. Safety: Ensure the safety of operators during the maintenance process to avoid accidents such as electric shocks and slips.

II. Maintenance Content

1. Exterior Maintenance
   • Regularly clean the exterior of the toilet to keep it tidy; check whether the doors, windows, and locks are intact and promptly replace damaged parts; ensure that the signs are clear and update them promptly when they are worn or fall off.
2. Internal Facility Maintenance
   • Clean the floors, walls, and partitions; check whether the flushing system is blocked or leaking, and clean or replace parts; check whether the sinks, mirrors, and lighting facilities are intact; clear blockages in the ventilation openings to ensure air circulation.
3. Sanitary Facility Maintenance
   • Regularly replace consumables such as toilet paper and hand soap; check whether the trash cans are damaged and replace them promptly; regularly disinfect to prevent the growth of bacteria.
4. Electrical Equipment Maintenance
   • Check whether the lighting and ventilation equipment are working properly and replace damaged parts; check whether the electrical wiring is aging and promptly replace hidden wiring.
5. Equipment Maintenance
   • Regularly maintain the flushing, ventilation, and lighting systems, check their smooth operation, and adjust abnormalities; lubricate the moving parts of the equipment to extend their service life.

III. Common Faults and Maintenance Methods

1. Box Deformation or Cracking: Repair small cracks with special plastic welding materials; when severe deformation or cracking affects the tightness, replace the entire box or related parts.
2. Door Lock and Hinge Faults: Regularly apply lubricating oil; when the lock spring fails or the structure is damaged, replace the entire lock set.
3. Flush Valve Faults: For manual or foot-operated flush valves, close the inlet valve and then disassemble to clean scale, replace aging sealing rings or springs; replace the entire valve body if it is broken.
4. Automatic Induction Flushing Device Problems: Check the power supply (confirm the battery level if battery-powered) and whether the infrared induction window is blocked by dirt; if the above are excluded, it may be a fault of the control motherboard or solenoid valve, which requires professional handling.
5. Storage Tank and Pipeline Leakage: Check whether there are cracks or loose connections in the tank and pipelines; use waterproof sealing tape to repair minor leaks; for large cracks in the tank, it is recommended to replace it with a new one.
