Water system

Here's what I've come up with for my water system.  I will run pex from the faucet on the porcelain container down under the deck and back up to the sink.  A couple of these 5 gal. jugs should be plenty for a weekend.  I'll know how many to take after a bit of trial and error, but I drank from one at home for more than 1 week.  So, I'm estimating 1 5 gal. jug per person for 3 days drinking, cooking, and washing hands, etc.  I'm going to purchase the caps that are resealable and fill them with tap water.
