we have a katadyn
40e, on our boat
that we run every day for at least a couple of hours.
We were managing ppm 250-300 which for the med is great, no problems.
Recently though we cannot get below 500 whilst underway, but as soon as we anchor
the numbers go back down to 250-300 !!?
Anyone else experience this?
I wonder if a faulty seal is letting seawater into freshwater side, due to movement whilst sailing/motoring., it used to be fine moving or anchoring
. It is 250 hours since new membrane and seals
Any idea please?
