I have an ATO tank that holds 14 g - to fill it I do need to carry 5g buckets water upstairs every Thursday evening. I would love to have a more automated system but like others I have the challenge of the tank being on one floor and the RO/DI in the basement. I have looked at simple ways to run a line from the basement to upstairs, but there is no easy way. Also like others I am afraid that a drilled hole in the floor might result in my premature funeral
. Having said this, I have found a way to automate my system somewhat - a 15 year old son who can carry the buckets of water upstairs! Sometimes this system is tough to get started, but it sure beats me carrying the buckets upstairs!
