Sam, do you know how the 'Fluid level sensor tube' actually works - it looks like it could work on air pressure??If I ever replace my Smart ATO, it will be with one of these so I can have an IBC 1000Lof RODI stored 30m away in my back shed instead of having my RODI unit squished behind the cabinet (hard to access and inspect) and would also free up the space the reservoir is taking in my cabinet:

Just get a Tunze ,
every other "smart" ATO has been a PIA for me.
otherwise, if you are using an APEX just add a float switch.
The 3155 is on my short list. I love Tunze products and the stream pumps I have are all excellent quality and reliable.I'm with @RobbieMVFC on this one - get the Tunze 3155 ATO (not the Nano) and you can't go wrong.
I have heard (not sure if its true or not ) Short spurts of On and Off RO/Di units will shorten the life span of the filters.The 3155 is on my short list. I love Tunze products and the stream pumps I have are all excellent quality and reliable.
Are you guys pumping the ro/di straight into your sumps or displays? I have read some differing opinions on this.

I have an RO section in my sump that holds about 60 liters.
That is correct with the TDS creep. I meant to say pumping RO/DI from a storage tank, not directly from the RO/DI unit :)I have a Tunze 8555 (RO/DI solenoid) that makes RO into my reservoir (about 50L at a time) and a separate 8155 that tops off from the reservoir to the DT.
You are correct - don't turn a RD/Di unit on/off quickly. The first 10-30 seconds isn't 0 TDS anyway ;-)
yeah I never understood that. People rave about the Tunze, despite having to constantly buy replacement pumps.... There isn't much more to a ATO than the pump!I have 6 of the JBJ ATO units and have never had an issue with them. The Tunze pump just died after a year of use, not too happy about that.
