Version 2 of the Drip Emitter is used to drain excess water from pots that have a hole at the bottom. It fits snuggly inside the hole--all you have to do is snap it into place. For an extra secure seal, you can use silicone around the edges. You can then connect a long piece of tubing to the end of the Emitter and direct it into a large container or reservoir, which will collect the excess water. The thicker nozzle allows for a better, tighter fit with the flexible tubing. Know how to make this part better? Have ideas for new parts?
