For a minute or two one afternoon, we had water with a brownish tint coming out of one of our bathroom sinks, and only when the hot water handle was on. The cold water was normal, and our other taps seemed to be fine. Is this a sign that some rust or silt build-up got knocked loose in the hot water pipe leading to that sink?
We weren't running hot water elsewhere at the time before the water turned clear again, so I can't rule out the water heater being the culprit. Is this a sign that it needs maintenance?
And in case someone asks, we've had a lot of rain lately, but no extreme weather otherwise (meaning, no frozen pipes).
