re: #22 Killgore Trout
Good tips. The water here in Portland really sucks, Very high PH, high mineral content and tastes like shit. I installed rain barrels on my gutters primarily for my hydroponic plants but I also use rainwater for making tea. I boil it in a french press coffee maker and haven’t encountered any cooties yet.
If your roof tiles are asphalt you may not want to consume the water runoff.
