I've just replaced 2 x 100gpd membranes from Daqua in my small 200gpd unit..................and had them running for two and a half hours. The resultant TDS before DI is 60 !!!!. I've taken them out, made sure they are seated ok, tightened all connections and resealed everything, but it still won't budge. Is this the norm. I filled up 3x25litre drums. i don't seem to remember waiting this long before for the water to settle....................or am I just impatient.
Yes, there is an 85psi booster pump on the system
I've replaced them because my previous tds was 24, but that was after a year of use of the membranes. I expected these to be lower within a reasonable time??
Thanks
