ok, the biggest use of water in my house appers to be the toilet. I will be building a gray water / rain water collection system for flushing and thought you all might want some pic's and details incase anyone else wanted to do this also. The main idea is as follows: 6 - 55 gallon drums to collect rain water and washer water 1 constant pressure pump, 12 volt rv style 1 deep cycle rv batt with solar charger so you get the idea soapy water from washer piped into drums, all drums connected rainwater is piped in also on a float to divert when full as I would not want the rain to go down the overflow. The plumbing I have with no prob, my question is do you think one of those float type chargers from Tractor Supply would have enough to do what I need? Pics to follow and as always, feel free to pick apart my idea and let me know what I may have missed.
