When I turn on the hot water I start to hear cracking or sort of expansion sounds in a couple of parts of the house. When The hot water is turned off
I still hear some noise. Is it the pipes or could it be the tankless water heater needing to be cleaned?
Probably just the pipes expanding and where they pass through joists or clamps they are tight so the pipes reposition themselves in small increments.
Then the pipes cool down and the process reverses.
States can help recovery from hurricanes and tornadoes by not requiring due digence or prompt and timely correction of substandard conditions, and by providing continued liability insurance where companies drop homeowners.
