I have relatively low water pressure. If I fitted a booster pump, my static tank would fill up quicker I take it, but would it improve the ppm coming out of the membrane (currently 14ppm)? Or have I got the wrong end of the stick?
you are right.
I check my tap tds yesterday it is 617
normally 470 ish, tds starts at 8 and goes up to 13 after filling 2000l of water and this is without a booster pump.
