Hooking up my ATO directly to my RO/DI

[YHSublime]

Hello WAMAS! I recently setup a UNS R60, which is a 32 gallon tank with a glass sump siliconed into the aluminum stand. Space is limited in the sump, and a big portion of it is consumed by a 2 gallon ATO box that gravity feeds to a float valve in the return chamber of the sump. 

 

Because space is limited AROUND the tank itself (now in the living room), I'm considering running a line from my RO/DI (in the basement) directly to the float valve return. 

 

Survey says this is a terrible idea, and if I've learned anything in my lifetime, its WHEN, not IF it fails. 

 

So I guess looking for advice, or DIY solutions to my ATO problem. If you'd like photos, or you want to see some of the solutions I think might work, my most recent posting here has it all laid out.

Do you have an ATO pump in your RODI reservoir that can pump into the tank vs float valve?

I know many also say that it can be safe to connect the RO system directly to the ATO if you you a solenoid.  I just dont like the idea of giving the tank unlimited access to fresh water. If you go this way, make sure you have a double backup system, with solenoid and float switches etc.

good luck

it’s a long run, coupled with about 9’ of headspace up.

yeah, even with the redundancy in place, I still don’t love it.
