Very nice! I hope yours works as well for you as ours does for us. It really has made things much simpler.
 
How do you guys like it? Pretty solid built? I haven't really heard anything bad about it rather than price.
 
After some debating and research, I went ahead and ordered the double switch sump mount one from autotopoff.com.

The seller shipped the product 2 hours after I made a payment. So I guess I could say, I'm happy with the purchase thus far! :)

It was only $50-60. It does not include the pump, but I have bunch of mini ones laying around the house.

I'll let you guys know how it works as soon as I get it installed.
 
You don't want your auto-top off to be connected straight to your RO/DI unit. If the top off system gets stuck in the "on" position for any reason it will lower your salinity, kill off anything in your tank, and flood your tank if you don't catch it soon enough. The safest way is to use a storage tank that you refill once a week or so.

Here's a top off unit I'm going to purchase soon, it's on sale also:

Thats the one I bought and it works great, but I had a problem when my power went off my overflow lost it's siphon and the pump ran the sump dry. Well the top off system kept filling it up and in turn the tank over flowed not fun. I'm going to put a battery back-up to keep this from happening again.
