I have an old (20yr?) Culligan mark59 with a small leak in the thin
black tube that goes from the regeneration unit to the salt tank. The
tube seems to be compressed at one point under the metal frame where
the plumbing pipes enter
the unit, and I think the tube is just slightly cracked under that
"pinch point". I see a small puddle of water on the top of the unit
under this tube, that then
drips onto the floor under the unit.
How do I remove the metal frame on top of the unit to replace this
Any pointers appreciated.
