Best article I've ever seen on a watering system! Lots of details, instructions, pictures showing products used. I even learned something about my own flawed PVC water system.
This is really nice! The instructions are clear, the pictures are great - step by step and nearly self-explanatory. The only issue I can find has nothing to do with the quality of the article or the waterer. I'd love to see one of these done for use in a region that freezes regularly ...
