I have not opened the pressure valve. Perhaps this is the issue. The user
manual on this for the D60 is very vague.

We make water while motor sailing. No problems and we have the Amel single
through hull for salt water intake. We never use chemicals for sterilising or
pickling. Just back flush with NON chorinated water from the tank with the
pressure valve totally released after each use.

On Aquarius, we also have this problem with our 24V D60. We continually
see an increase in the ppm each year. I have a few questions so we might
flush this out...
1) Do you have a pre-pump that feeds your high pressure pump?
2) For those that have a pre-pump, do you see this problem?
I am starting to get the feeling that cavitation do to air in the system is
causing the problem on Aquarius. We only have a single sea water intake,
stock Amel, and we do make water while motor sailing, and this could cause air
to get into the water-maker system. With the air in the system I am led
to believe this is like a jack hammer on the membranes causing micro tears to
form. Overtime, the holes get bigger, and whaalaa 1000 ppm.
I don't have the pre-pump on Aquarius, but I am planing to add the pump when I
install new membranes in about 6 months.
Does anyone have any thoughts about this?
