Last week we took our TT to out for the first trip this year. The winter being so long this year I could hardly wait to back into a site and hook it up.
Took my time and checked everything. Being the first one on the site it was clean and ready to go, so I thought. After hooking up the water I noticed dark stuff in our newly installed water filter. It appears while the campground water supply was pressurized no one ran the water to flush the line.
Couple of hours later a new filter, cleaned lines and screens.
Lesson learned - Who says you can't teach an old dog new tricks.
