ok....great.....I just have to find out how much cold water flow i need for the filter to figure out what mods i have to do to my cold water copper pipe. Was at Canadian Tire yesterday and found a quick and easy way to connect my cold water copper to the filter similar to how this filter is connected...it's just a clamp that has a self tapping bit that goes right into the copper...similar to how my humidifier gets its cold water so I don't need to hire a plumber to put in a tap for me...hope this is sufficient to get the water through the filter and into my tank...I'll be looking at changing approx. 500-600gals of water per week.
