I have a culligan mark 59 aqua sensor water softener. I have had it since 1982? The timer keeps stopping and I got to whack it to get it going. The culligan guy said I should get a new unit because they donít make parts for the 59. Also said my tank needs cleaned out because it is restricting my water flow. They can clean my tank and but new stuff in it for $500. or a whole new unit for $1300.

What do you think?
