I have a Dessaltor 100 duo and I'm seeing very erratic pressure to the point where its unusable. In the past I have remedied this by replacing the pre-filter, but this time it has not solved the problem. One thing in the troubleshooting section in the manual is that may be related is belt tension. Would anyone know how to check for the correct belt tension as the manual does not seem to say anthing about this. Failing this, any other ideas would be very welcome.
