QuoteReplyTopic: Would this idea work for a gravity fed ATO Posted: August 19 2012 at 5:21pm
I was thinking of making a non-electrical, gravity fed auto top off. I looked online for the design I had in mind thinking that a lot of other people do this and wanted to see how they made theirs. I couldn't find many designs at all! So it either doesn't work, or I'm a genius ;)
I was thinking of making a shelf above a sump and putting a 5 gallon Home Depot bucket full of RO water and installing some airline tubing on the bottom that would connect to a float valve (like this one: http://www.marinedepot.com/Eshopps_Float_Valve_Auto_Top_Gravity_Feed_Dosing_Pumps_Top_Off-Eshopps-QH03531-FIDPGT-vi.html) in the sump. Has anyone tried this before?
Gravity fed top off's work great. I utilized a 5G water jug on a drip system on our 90G for almost 10 years. When we upgraded to a 400G total system, I had to upgrade the 5G to a 30G. I changed out the drip to a float valve about 6 months ago. Works like a champ.

A government strong enough to give you everything you want, is powerful enough to take everything you have.
What I did was drill a hole in the top of the garbage can and pushed tubing to the bottom. Than ran it to a float in the sump. I'd that makes any sense.
I'll try for some pictures later today. As far as connecting the tubbing to the reservoir, I simple ran it over the top and down to the bottom of the container.

Make sure your float doesn't have copper or any metal in it. Home dept and Lowe's all have metal. Buy a Kent's float. This is a very common thing us salty guys use
