RO/DI unit question

[Indermark]

My RO unit is taking forever and a day to fill up a 32 gallon Brute trashcan. (75GPD membrane its doing about 55 GPD). I started last night at 10 filling up this 32 gallon container at 12 today it still wasn't full it was only 3/4 full. I was wonding if I could warm up the water and speed up this process by turning on a little of the hot water on the sink. I understand that HOT water will ruin the unit but if I get the water coming out of the faucet at 70 degrees thats not neccesarilly hot now is it? I just wanted to make sure this was going to be safe to do and if anyone else has done this? I really don't want to replace anything that might be ruined.

Some people get a long line of the ro/di plastic line and make coils in thier sumps (if room for it) to heat it up and speed the process up.

my ro/di unit is no where near any of my tanks.

You can do this with a bucket of regular tap water. Just get a 5 gallon bucket of warm water. Add a small heater to keep it warm. And maybe a small pump to keep it warm throughout. Then get a whole lot (about as much as you can fit in is probably best) of the rigid tubing you use to input into your RO/DI and have it go through that bucket of warm water first. I've never actually tried this but have read about it and it seems like it would work.

that does seem like a good idea.

With tubing length of around 50 feet + it becomes self defeating - you start losing water pressure due to the internal friction with the 1/4" tubing.
