hey Gary.

one thing still mystified - why does the salt show up in the HOT water
tap and not the COLD water tap???

I don't think it's salt that is causing the residue, although it may be.
It might be more chlorides than sodium though and coming out of solution
only in the water heater and hot side plumbing.

I don't know whom originally posted this or what the complaint was but if
the problem is only in the hot water lines, chances are good that the
problem is caused by a deteriorating 'drip tube' in the hot water heater.
Several manufacturers have had service programs because of this and it would
even cover cleaning all the hot water fittings which would be affected by
such a failure.

The OP should contact the manufacturer of the hot water heater to see if it
is effected by this particular failure. You can read a bit about it at the
