im torn between brands of tankless water heaters, anyone have a favorite or brand to stay away from? Im thinking Noritz or Rinnai and it seems all the companies have bad customer support.
I believe the primary reason for the 3/4" connections is to minimize pressure loss at maximum flows.So if I have a 3/4” cold feed can I reduce the hot down to 1/2” after a few feet? Most of the hot water pipes were previously changed to copper by somebody before me. Will the tankless still work as it should?
You might consider taking your 3/4" line , from the water heater , to a fitting with 1 - 3/4" & 3 - 1/2". To feed the 2 bathrooms and kitchen .
