Calgarys' water...

[MitchM]

Before, when I went away on a trip, I had the people that looked after my system just add cold tap water to the system for top-off. The amount was between 5 and 8 gallons a day. I didn't have a float switch hooked up and didn't trust them to run my RO/DI.

...No difference...

:?

Long term, I feel better using RO/DI, but I'm not so sure it's really necessary.

But I think it looks cool.
