How to Install the Fecal Tank for Mobile Toilets

There are two ways to install the fecal tank for mobile toilets: the independent fecal tank type and the connected septic tank type. The specific installation steps are as follows:

The key to installing an independent fecal tank type mobile toilet lies in sealing and convenience. This type of toilet usually has an independent fecal tank at the bottom, which directly collects feces into the tank through an internal diversion structure (such as a slope or a feces guide plate), without the need for external pipes or a septic tank. When installing, it is essential to focus on checking the connection between the fecal tank and the toilet body:

1. Sealing treatment: Use rubber sealing rings or silicone sealant to seal the interface between the fecal tank and the body to prevent fecal leakage or odor diffusion;
2. Reserved cleaning port: Reserve a detachable cleaning port (such as a threaded cover or a quick-release plate) on the side or bottom of the fecal tank for subsequent suction or manual cleaning;
3. Fixing and anti-slip: Securely fix the fecal tank to the bottom of the toilet with bolts or buckles to prevent displacement during movement. At the same time, ensure that the bottom of the fecal tank is in stable contact with the ground to prevent tilting and fecal overflow.

The installation of a connected septic tank type mobile toilet requires consideration of both pipe connection and anti-seepage treatment, which is suitable for long-term use or scenarios with a large amount of feces. The specific steps are as follows:

1. Septic tank positioning: Choose an area with an elevation higher than the toilet body and smooth drainage (about 1.5 meters away) to avoid rainwater backflow or sewage backflow;
2. Pipe connection: Use PVC pipes (with a recommended diameter of over 110mm) to connect the toilet outlet and the septic tank inlet. Add sealing rings at the interfaces and fix them with PVC special glue. At the same time, install an anti-backflow valve (such as a duckbill valve) in the middle of the pipe to prevent gas or sewage in the septic tank from flowing back into the toilet;
3. Backfilling and commissioning: After the pipe is laid, backfill it with sand and gravel (about 20cm thick) and yellow soil (about 30cm thick) in layers, and compact each layer to avoid settlement. After backfilling, conduct a drainage test by injecting clean water into the toilet to observe whether there are any leaks at the interfaces between the pipes and the septic tank. Only put it into use after confirming that there are no problems.

Selection suggestions: If the site space is limited or frequent movement is required, the independent fecal tank type is preferred. If the usage period is long and there is a large demand for feces treatment, the connected septic tank type is more suitable. Before installation, adjust the plan according to factors such as the site slope and soil type (such as strengthening anti-seepage for clay) to ensure compliance with environmental protection and hygiene requirements.
