Merlin problem...
« on: October 19, 2011, 04:49:26 pm »
Hi guys..

Our Merlin in producing water (before resin) at 50-60 ppm. Its pumped through at 70psi.

Now the thing is, we were running it at tap pressure (about 25psi) for a week or so, while we found the right pump, could we have damaged the membranes or should we persevere in the hope that tds comes down?

Cheers

if your tap water is 370...then a tds of 50-70 is quite normal for a small RO like merlin isnt it?

my subby has one....his tap is around 200...he gets 20-30 out the merlin i think
