Title: It's a hammer.
Review: The unit will hammer the water system. Unfortuately I will be replacing my water line because of the impact of the hammering. I had been gone for a week and returned to find my older galvanized pipes could not take the impact and failed. [Upside, the damage was not in the house.]
