How to Connect the Hose of a Portable Toilet

The connection method for the hose of a portable toilet should be handled differently depending on the specific use, with the following specific steps:

I. Connection of the Inlet Hose for Smart/Automatic Toilets

1. Confirm the Interface Type: Check whether the reserved water supply interface is a standard 4-point threaded inlet (common in household water supply systems).
2. Sealing Treatment: Use the provided sealing tape (PTFE tape) and wrap it 5-8 times along the thread direction, ensuring full coverage of the threaded area to prevent leaks.
3. Tighten and Secure: Align the threaded end of the hose with the interface and rotate it clockwise until fully tightened. For quick-connect interfaces, press the hose against the slot until you hear a 'click' sound, confirming that the clip is fully engaged.
4. Function Test: After connection, slowly open the main water valve and observe for any leaks at the interface. At the same time, activate the toilet's cleaning function to check if the water flow is unobstructed.

II. Connection of Drainage Pipes

1. Toilet Drainage:
   • Use a flange ring (wax seal or rubber material) to seal the connection between the toilet drain outlet and the PVC drainage pipe, ensuring the flange ring fits snugly against the pipe opening to prevent odor backflow.
   • During installation, maintain a slope of 2%-5% for the PVC drainage pipe to facilitate natural drainage of sewage.
2. Sink/Floor Drain Drainage:
   • Connect one end of the hose or PVC pipe to the equipment's drain outlet and the other end to the branch pipe.
   • Add a rubber gasket at the interface to enhance sealing and tighten it with a pipe clamp to prevent loosening and leaks.
   • When connecting PVC pipes, apply special adhesive at the interface to ensure a firm bond.

III. Connection Methods for Exhaust Hoses

1. Water Seal Method: Reserve a U-shaped water cushion, insert one end of the hose into the exhaust pipe, and connect the other end to the sewage pipe through the water seal, using the water seal to block odors.
2. Vertical Upward Method: Insert the hose directly into the exhaust pipe and stand it upright, requiring regular cleaning of dust inside the pipe to prevent blockages.
3. Oblique Upward Method: Insert the hose at a 45-degree angle into the exhaust pipe, requiring special tools to secure the hose, which is more costly but offers better exhaust efficiency.
4. Skewed Mouth Method: Connect a bowl-shaped protrusion to the end of the hose, using the physical structure to prevent sewage backflow, but installation is more difficult and requires professional assistance.

Precautions:

• Before installation, turn off the power and water supply to ensure safety; novices are advised to contact after-sales service or professionals for assistance.
• Regularly inspect and clean the exhaust pipe to prevent blockages caused by dust or foreign objects, which can impede exhaust flow.
• When installing PVC drainage pipes, strictly control the slope and apply adhesive evenly at the interfaces to prevent leaks.
