Hi Tom,toggle quoted messageShow quoted text
500 ppm is considered the upper limit, anything below that is acceptable for drinking water. However once the membranes get to the point of delivering either 500ppm of close to it they are arriving at replacement time. 280 is acceptable and of course at start up you will see higher levels. My duo 60 has manual controls and I run product water to waste for a couple of minutes after start up. So long as the tds goes down to an acceptable quite quickly dilution would deal with it. 0.75l/m is not far off 60 l/h the and if you give the watermaker some long use you may find you get it up there. So in summary. 500ppm is the upper limit but you wont die if it is a little higher. Anything in the mid 300 and below is quite acceptable. Once my tds gets over 400ppm on a regular basis I start planning for replacement. Like anything, the best treatment is regular use.
