low water pressure
Posted by leigh on March 09, 19101 at 18:19:21:
We just finished a major renovation, which included a new bathroom (shower no tub, sink, toilet) downstairs.
New tankless water heater is upstairs. In old bathroom (when the traditional water heater was downstairs)
we had plentiful water pressure in the shower. Now it's wimpy, for both hot water and cold. So wimpy, sometimes the water heater
shuts off, presumably due to inadequate demand. The cold/hot control is a single lever. What could be
causing the low water pressure?
