The garage siphon drainage system utilizes the siphon principle, taking full advantage of the pressure difference in water to continuously generate siphon action within the drainage channel, thereby achieving the effect of rapid water expulsion.

2. Currently, on large-scale garage rooftops, it's common practice to use durable waterproofing membranes and siphon drainage channels together to divide the rooftop into several smaller sections. These sections are then collected individually and eventually aggregated into the final drainage pipes.

3. The PED14 high polymer protective drainage sheets, when combined with geomembrane, rainwater pipes, inspection wells, water storage molds, and waterproof membranes, form a rainwater purification system. The purified water is then stored in a reservoir for subsequent use in irrigation, toilet flushing, and car washing. This solution is not only economical and environmentally friendly but also saves a significant amount of water, achieving multiple benefits at once.
