Product review (3 stars): Initial Review
The hoses have a narrow width and restricts water flow and is messing with the sensors on the unit.  You'll need more water pressure in the line to account for less volume.  In typical american fashion, this will wear our the hoses and cause me to have to buy more in the future, or wind up with a flood, waste of hot water and thus fuel.  Happy???  not sure yet.  In 4 years, if I have to by new ones, you'll see this revised to 1 star.
