Sorry Charliez - didn't mean to take so long to get back to you. You are correct in questioning whether the system worked properly in the beginning. In hindsight, I don't believe it worked as well as I'd like it to. Let me explain - From day one I thought it took an inordinate amount of time to fill the tank, but I had no basis for comparison as this was a new coach. What I did notice was that as time went by, it took longer and longer to fill, and changing the filter did not seem to make any vast improvement.
What did make a vast difference was to remove the filter completely and then replace the housing. Then, the flow rate soared. So, it appears that the problem lies in the flow rate of the filters I have had installed. What I need to do now is find a filter that has a fairly rapid flow-through rate.
Does this explain it any better?
