How do you stop RO lines from sweating?

[pecan2phat]

Somebody out there must have figured out how to stop RO tubing from sweating. I covered my cold water pipes with styro wrap but is there something that you can wrap 1/8" RO tubing to stop or cut down on the dripping?

Turn on the A/C-- sorry warren I couldnt resist

A dehumidifier's about the only other thing that'd do it, unless you can warm the water entering your RO system.

Vaseline?

Not sure if your water heater is close to the RO.

Wrap 30' of input water line around the water heater to heat the water, you get better rejection rates and no more sweating.

I never saw my lines sweat are you sure they aren't leaking? I use the plastic lines and use a lot of ro water

My lines are run off cold water and its a little humid in the cabinet. I've never seen sweat come off the RO tubes but i do have sweat on my regular water lines that are a few inches away from the RO.

Only fix is to heat the water up a little or cool down the area that the lines are in.

It's just part of the RO process some units swear more than others. Do not use warm water or try to heat it, That will destroy you filters and cause them not to work properly.

Your RO must be from Jersey Shore :lol2:

RO membrane works better with warm water, I wouldn't use hot water from your hot water tank thou.

i heat the input water by going around my hot water line.... works great....

Good idea smokn

Most R/O units work best on water that is between 90?F and 110?F with a pressure of between 80 and 100 PSI in the winter my tap cold water is around 47?F which causes my R/O unit to slow. I have my water lines run under the foam insulation of the hot water pipes which warms the water and keeps the flow higher all year round.

As long as you are not using hot water from the water heater it should not shorten the life of your filters. The reason hot water from the water heater does is because the inside of the hot water tank has rods that rust and rot to keep the water tank from rotting away. These rods add impurities to the water and cause the filters to work harder shortening there life.

As for the sweating you could wrap the lines with foam packing sheets like these ( http://www.uline.com/BL_864/Foam-Sheets ) I seen them at Staples and such and tape em. This will keep them insulated. I did that for my ice maker lines when they were sweating.

? --the booklet that came with mine said not to ever exceed 104 or else will damage the membranes- I always heard 77 degrees is the ideal temp. May be wrong but I believe that the operating water degree range of units is in the 70's with psi of 70 - 80 to operate at their optimum

You should always check your specific membrane requirements I said most not all. and 110 was a typo I meant 101 thanks for pointing that out.

77 is the temp that lots of membranes are tested at that gives their rating 100GPD

There are lots of factors that come into play that reduce that number

Temp, PSI, TDS, PH and Back Pressure to name a few.

I read this in a PDF from my RO/DI unit I will upload to my web server and post a link when I locate it.

insulate the lines with foam isulation wrap it comes in a roll about 2 inches wide around 20 feet per roll try home depot or a plumbing supply

 

[JimmyR1rider]

LOL ok 101 sounds more like it along with the rest of the figures that my units manual said

 

[motortrendz]

i was waiting for a punchline...wtf lol hahahaa

 

[pecan2phat]

Thanks for all the suggestions guys.
