How many GPD is your R/O unit rated for? Also, what is the temperature of the water? The colder the water, the less R/O you get in my experience.

Hi Harvey its a Aqua-safe 100 GPD ("RO+DI") SYSTEM 6 stage. I'am not sure of the water temperature will check that tonight, would you suggest mixing my source water with both hot and cold?

BAD!!! No, that's a really easy way to kill your membrane. From what I've read, you can get 25 feet of the same tubing that connects from the water source to the in of the filter, coil it up and submerse it in a bucket that has a small heater in it keeping the water @ 78°f. That will help boost your production.

coil the cold ro tube and leave it in the sump...instant chiller

Just curious, why would warm tap water kill your membrane but warmed water through a coil would not?

I think Dan is implying that there is more room for error (i.e. accidentally running only hot water to the unit) when hooking it up to the hot water line and killing your membrane.

the warm water from the tap (hot water heater) could (usually does) contain heavy metals that leach out of the tank. I use warm water from the tap makes a huge difference in RODI water production
