High temps, how to protect tank?

[littlesilvermax]

I run 100 feet of RO feed line through my sump.

Cools my sump and warms up my water before the RO unit so there is no condensation on the unit and it works more efficiently.

Total cost $8.

That will work as long as you have good city pressure.

At 100 feet of tube, you've made a conciderable pressure drop at the r/o unit inlet.

You think? Its only 1/4" tubing. From my RODI to my tank is about 50 feet, twisting and turning, and there is no pressure problem, and that is after the RODI, not before.

Easy enough to test, and the tubing is cheap!

After doesn't matter at all. (Since it just trickles out of there anyhow.)

But, there is a minimum amount of pressure required before the r/o membrane.

I just think any normal house pressure would be adequate to pump water 100 feet through 1/4" line. There must be a formula for figuring this out there, any fluid dynamics people out there? I haven't touched that subject since second year engineering!

It was mentioned to keep a fan handy for the nano, this would be good for both tanks actually.

I have absolutely no pressure problems.

You can always get 3/8 tubing.


Also the increase in temp will help your ROs efficiency. I saw 40 gpd before and 55 gpd after.
