Little white "rocks" in the hot water
Posted by JGB on November 15, 1999 at 14:20:18:
My hot water lines are plagued with little white "rocks" that I assume are some kind of calcium or lime build up coming out of the water heater. I have drained the heater a couple of times to try and reduce the rocks, but they are still coming (by the way - draining the heater did yield a huge number of these "rocks" as well).

How can I get rid of these annoying things? I have to clean out the screens on the sink faucets every week to keep the pressure up. Is there some kind of filter I should install after the heater? Help!
