Lower flow into holding tank??


Greener

Recommended Posts

Hi all, please can you help? I have recently brought a used van set up, when I brought it the system was purifying the water at a reading of 9ppm, I have changed all the pre filters, membrains and di resin and am happy to say it is now producing 100% pure :clap: however I have noticed that the flow of water coming from the di vessel into the tank is somewhat slower/less flow than before??? Could this simply be because the new filters etc are now running more efficient than the old filters? Just wandering if this is a common characteristic?

 

Many thanks Greener :yawn:

Hi ya, natty1972;) no I didn't ? I flushed one of the pre filters as instructed on the fitting instructions but not the membranes before fitting?? I did however carrier out a system flush for about two hours before connecting to the di vessel??

Did you flush your new membranes ...

 

 

I find the flow slows in colder weather ....

You don't flush your membranes before fitting. You flush them for a bit after you fit the new ones into their housings and reassemble the r/o. Chlorine in the water damages membranes; that's why you have a carbon block filter as one of the prefilters - to remove it.

 

Just carry on as you are now. Water production decreases when the water temperature input drops. There is a big difference in viscosity between water at 20 degrees and water at 5 degrees C. The 'thinner' the water the easier it is to push in through the membrane pores.

 

The best example is old engine oil. When it's cold its thick but when hot its thinner.
