I am an avid gardener and have constructed a closed-loop rain gutter system similar to this: https://www.youtube.com/watch?v=NyOIRVjatdg.

I wanted to use the original Hydroponic Drain by Vik to connect everything, but soon found out that the drain was not exactly what I needed.

I use the most common gardening irrigation hose around. It is the 1/2" hose by Rain Bird.

The original drain was a little small and required a hose clamp to keep it together. I addition, the single-barbed neck proved to be too weak and snapped easily.

My version features three larger barbs that not only fit the Rain Bird hose perfectly (eliminating the need for tools), but provides a leak-proof connection and much stronger structure.

Let me know if this works for you!

V3 has an even stronger neck while maintaining the drain size as the original.
