rvdog Report post Posted November 5, 2012 Recently noticed that we are getting some kind of black sludge from the fresh water tank. First noticed it when we flushed the tank to replace the water pump. It now seems to be clogging up the water pump filter. We use the system for flushing, washing and showering. (We get drinking water from jugs.) Any way of getting rid of this--not sure if re-sanitizing will remove this stuff? Share this post Link to post Share on other sites

I would open the tank drain and then add some water... repeat 4-5 times, THEN sanitize and flush a couple of more times. Share this post Link to post Share on other sites
