RO/DI running slow? cold outside? Solution!

My 100GPD RO/DI was reduced to a drip. It has been fairly cool here at night. My RO/DI is in the garage. I assumed the cold was probably effecting my production.

While surfing the web, I came accross this site:

It states the following trick:

Replace the tubing that leads from your cold water pipe to the unit with a 25' long piece. Coil as much of that tubing inside a 5 gallon bucket and fill the bucket up with water so the coils are submerged. Put an aquarium heater in the bucket and set it to 78° F. The heater will keep the bucket water at that temperature, and that water will warm up the water traveling through the tubing to your RO/DI unit. Production rates will jump back to normal.
I tried it and now my RO/DI is producing like crazy! If you are having troubles with yours this winter, I HIGHLY recommend you try this!

Yep. the colder water makes it less condusive to the RO process. There is some math formula for calculating the decrese in production based upon the intake temperature but I dont know it.

10 Kudos for that tip. I'm rarely affected by low temp, but every once in a while...

Thanks for that tip!

Yes, thank you. Sounds like low temp is probably to blame. The water around here is nowhere near 78 degrees even in summer. I will definitely try that. Very clever.
