I've been suffering with a Kenmore softener for 10 or so years. It has only worked for about half the thime I've had it.

Currently I've let the salt run out so I can clean the Morton pellet residue from the bottom of the salt tank, it has been plugging up the brine valve.

I just noticed that the outside of the resin tank is delaminating, it looks like the yellowish fiberglass (or whatever it is made of) is cracked.

Does this affect the operation at all? I don't know how these tanks are constructed.

If it needs to be replaced, it's time to ditch the whole thing. I need to replace the rotor and seals already, about $100 in parts, if this tank needs to be relpaced too I think it's time for a new softener.
