How do you change the amount of waste? I got mine from Pure Freedom and the 4040 was already set.

an air lock could also slow your water production down, do you have any drips anywhere ?

i had the same problem with our 40-40, my water in is 545ppm

i bet if you take the membraine out and look down it you will see little white bits between the paper (limescale)
you will no doubtly need to put a water softeren at the start of your system
