Is there no way to drain the tank? A good place to start would be to replace any
brass or steel fittings that take the water in and out of the tank... they may
very well be where your mineral build-up is. If you can drain it -- or even if
you can't -- white vinegar does wonders for loosening up mineral deposits. It is
a mild acid -- quite benign. Let it sit at least overnight, if not longer. Then
flush thoroughly, preferably NOT through the trailer's water system -- hook the
outlet to a hose (with a hose clamp) and run the water outside. It will be full
of pieces of minerals.  ~  Rik
