Got a question:

I started making Ro/di water this afternoon for the first time ( after letting the first few gallons get out).

Anyway, my ro/di is hooked up to the hose connection outside. Its currently 37 degrees, but will get to about 20-25 ish or so by the time I get the 25 gallons I need. Is it ok to continue to keep the ro/di going or should I bring it in and continue making water another day? I dont want to damage it. I know generally water only freezes if its sitting still, and this water is constantly moving through the ro/di. Help! :) I need water for a water change, but of course dont want to damage my brand new ro/di.

thanks!!
 
Right now the hookup ( whole unit) is outside because the faucet is outside. Once its done, I'm bringing the RO/Di in the house and storing the water in the garage. I just wanted to make sure its going to be OK in those temps while I'm getting the water.
 
A hard call to make on that one. I will caution you only because I'm having to replace my entire unit due to leaving it out to get a few more 5 gallon jugs filled up.....very stupid on my part and I'm now learning a hard $250 lesson.

I'd say get whatever you can before the temps drop too low. Make the rest during the day tomorrow.

Good luck!
 
I keep mine in my tool shed. The water hose is outside and comes in to the toolshed. If the unit is outside I`d bring it in.
 
Sounds good. I was able to get about 10-15 gallons before bringing it in. So far so good. Thanks for the help :)

Your not moving enough water through the unit to prevent it from freezing. Your unit produces water at a GPH or GPD rate.
Water coming out of supply lines in the groung hovers in the mid 40'S or so depending on location. You would need a decent
GPM flow rate to keep the unit from freezing once the temp dropped below 30 - 31'F. Even then the unit would freeze from
the outside in. Just much slower. Water does funny things below 34'F or so.
I wouldn't take the chance below 35'F in the shade.
