Auto Top Off
 

I asked someone in here before about this but now I can't seem to find the thread. I need some ideas for a low budget do-it-yourself auto top off system.

Do you have kids? :lol:

One 9 month old.

How big is your system? Are you looking for a gravity fed ATO or pump-style?

:biggrin::lol:

System including sump about 150gal. Probably looking at a pump style system. I should have asked...what do kids have to do with it?

Kids are a very economical ATO solution. Although you won't be able to apply yours for a little while yet, so carry on. :lol:

I use AutoTopOff dot com's auto top off solution on both my tanks and have been for a while now. The thing I like about theirs is that there's a backup shut off switch. You can easily make your own employing the same components and I tried but I could not find those float switches in the city for the life of me. If you can find those float switches you're off to the races. That's pretty much all it is. Mount float switch, when water drops, float switch activates your ATO pump which pumps fresh water into your tank which raises the float switch back to the OFF position.

+1 on the autotopoff.com units. they are priced well and work well. You could probably build one yourself for a little less but then you have to source the parts, assemble etc. So if you want to spend a little more you can have a plug and play solution.

Thanks for the replies. I work in the oil & gas industry so I have a good understanding of level controllers and access to suppliers although most of ours are pneumatic. I'm sure if I do a bit of digging I could find an electric one.
