Question about ro/di and ATO

[DiverDude]

You need to be careful as not all RO/DI systems can work with a float valve. The valve just builds back pressure which not all systems can handle.

Just be sure to tell anyone selling you a system that you want it to run unattended on a float valve.

i was under the impression that a check valve of sorts was attainable to add on to counteract the back pressure?

was I misled?

Thank you very much for the advice.

You should look into getting a solenoid to positively close the RO. It could use the information from your float valve when to I/O.

I run my RO/DI directly to my tank with a float valve and auto shut off valve.
There is no problem so far.
