I have a whole house filter setup outside the 5er. Unfortunately, it doesn't help the sediment problem. Once or twice a year, I'll have to unscrew the 90 degree elbow to my freshwater line and clear out any gunk that has built up just in front of hose washer/screen. I know when it's time to do that because the water pressure inside the RV drops drastically. This last time there was a palmfull of stuff in the elbow. Looked like coarse sand or very fine gravel. Only a pinhole was open for water to go through. Fortunately, it shook right out of the elbow. Now, I'm trying the screen closer to the water bib since the elbow is in a tight compartment and not easy to work with.
