Does water proud unction slow down in the cold weather?
My pumped 4040 was doing 600l in 2 hours in the summer, tonight is still running after 3 :o
-
yes due to the viscosity of the water systems often produce at a lower rate when its cold
p.s. the chocolatiers forum ;D

I always assumed that water is "thinner" (not sure of a better way of putting it) when it's warm.
OK let's take this to the extremes.
When water is very hot it becomes steam.
When it is very cold it becomes ice.
However, this loosening/compacting process also happens within more mid range temperatures but we can't see it with the naked eye. Therefore warm water will flow more freely than cold water. For most purposes it makes no difference.
Apart from that, I assume Lee GLS changes his pre-filters regularly? Don't want to wreck those membranes by leaving them in too long.

RO is temperature sensitive. There is an optimum temperature and as it gets colder the process slows down.

I have a 40/40, pumped it's doing around 200 ltrs per hour at present, takes around 5 hours to fill my 1000 ltr static tank, in summer I expect it to fill in around 3 hours(hopefully).
