Drain Funnel 漏斗

thingiverse

I'm talking about my household toilet's water outlet. It's not located at the bottom of the toilet bowl, which means that after flushing, the water doesn't flow properly out of the drain. To fix this issue, I came up with a simple solution. I created a device and placed it in the drain pipe. To use it for draining into a U-shaped pipe, you just need to insert a branch pipe above it. I used a 5-liter plastic bottle. After using it for a week, there haven't been any problems so far. You can check out my DIY solution on YouTube at https://youtu.be/nX3zz1W1hoE and https://youtu.be/7BHMTNBvB9Q. The file with the design is available in STL, STEP, and Fusion 360 formats. You can modify it to suit your needs.
