I discovered today that salt has entered and become encrusted in the main body of my water softener - picture here:
Recently I noticed that the salt in the proper compartment had completely run out. I replaced it as soon as I realised but I don't know how long it had been gone: not long, I think, since the water showed no signs of hardening, but could that have been the cause? Is the salt in the main compartment doing any harm? Should I remove it?
Many thanks.
