Best way to connect and seal two plastic water containers?
I'm launching a little balcony gardening project that involves water reservoirs. I don't have much experience with these kinds of projects, so I need a little help.
Due to some dimensional constraints, I will need two regular plastic containers (your typical storage containers), and I was hoping to get away with only including a way to fill one of them. That means I will need to connect it to the other in some way. So I thought I would just drill a hole in both of them and stick a pipe between them.
What is the best way to drill holes in plastic without risking any splitting?
How do I make sure that the holes are water sealed afterwards? Can I glue around the pipe and plastic box?
Would it be possible to maintain at least some water in both containers? If so, a simpler approach might be to try a siphon. Here's an image showing a (way bigger) example, but the theory would be the same for your containers.
Thanks for the suggestion. I think it would be difficult to maintain water in both, and I don't have too much leeway in terms of height differences either.
