Something else to think about:
after inspecting the city water plumbing connections which run behind the
fridge and cabinets, I decided to never use the city water connections. I
am concerned that one day the pressure on these whimpy connections will
cause a leak. The lead could run for hours before being noticed and do a
lot of damage. I just decided that if I have city water, it's easy enough
to put some in the tank and use my pump. That way there is no pressure
working away behind my fridge (a small spray on fridge electrical
components, I shudder to think!)
