What We Get Called About Most in Castle Hill

Most calls from Castle Hill come down to two things, and both are regional. The water is among the softest in the country, 7.2 to 22.1 grains per gallon, which most people read as harmless — but water that soft strips protective scale rather than leaving it, and works on copper fill lines and valve bodies instead of furring them up. And the climate never lets a door seal dry out, so gaskets perish rather than crack, which passes a visual check and still leaks.
