I'm wondering about the inlets and outlets. Do you filter the water? How do you make sure it doesn't get nasty/moldy/mosquito heaven. Do you have a pressure pump or gravity feed?

I'm fumbling my way through all this. At this point I am putting the water through a screen as it comes in. Gravity feed on all of them. I plan on covering them to help prevent muck from forming. They are all for watering plants.
