Auto top off system

[drillsar]

Im looking for a auto top off system I looked at JBL and Tunze which ones better, any other suggestions?

not familure with either...how about a link..
do you want to have the top off coming from the ro/di or a bucket/tub of water. I know a few people who use a leter meter and say its the best way to go. No real chance of a major dose of fresh water lower the SG with them.

I have done tons of research on this subject. Because I travel a lot for business, auto top-off is essential as my wife often forgets to add water.

There are positives to both systems. One advantage to the Tunze system is that it doesn't have any moving parts because it uses optics versus a float system. The JBJ system costs about 100 less and also has a built in fail safe.

There is another system to consider at:

Personally, I went with the JBJ system which I really liked for the $$

If you can plumb a line from the RO and find a way to hide it, I still think the float switch is the cheapest, easiest and hassle-free way to go.

A crawl space comes in handy for this.
