right, this is now absolutely doing my head in here.
my tds crept up a bit, and was advised to buy new filters for my merlin, which i have done, at great expense...
checked the tds after the merlin, and after an hour or so, it was 75.
was advised to move the system to as close to the mains outside tap as possible, which i have done, so there is now about a foot from tap.
production up to 1l per minute, however tds after ro is now 65.
at this rate, it will eat its way through my 6.5l di vessels resin at a rate of 1500 litres per refill of resin!!
absolutely pulling my hair out here....help please!!
