I have tried those water hose filters like you are using ... the water in some areas just doesn't take much to load them up. Not endorsing Camping World, but here's
an example of what works alot better for me.
http://www.campingworld.com/browse/s...12874&src=SRQB These use more of a whole house filter element that can easily be found at any Walmart. Actually the filter assy can be bought at Home Depot, Lowe's, or Sutherlands as well as the garden hose fitting adaptors.
After reading your post again .. Did you mean to say it
isn't the filter???
