Changed my prefilters and bled the system, heh ho my old problems return. Blows out water everywhere from the top of the filter housings, To the great delight of my little son ' daddy you're all wet!'
Spent two days trying to bleed it, same as last time no joy.
Then thought I would measure the water after going through the membrane, thought I could hear air gu in the membranes.
Water after membrane 1 was 18ppm but after membrane two was 53!
I had also noticed a drop from 80 to 70 psi.
Reckon my number two membrane has had it.
As a quick fix have disconnected the second membrane and am running back at 80psi.
Just ordered two new membranes.
From memory I don't think they have lasted that long.
Incoming water is around 280ppm.
I do back flush as well.
Hope I've sorted it.
any thoughts guys?
