In my area, the water is very hard, so most dental offices install a water
softener.  There is a solenoid switch that turns off all the water to my
unit.  This is so that if a pipe bursts, only the water in the line would
leak out since there is no more pressure.  However, since the softener must
regenerate when water use is very low, it runs at night, so the softener is
not on the solenoid switch.  Go figure.

Anyways, I lost 5 computers since the towers were on the floor.  My server,
thankfully, was OK since it sits on my desk.  The humidity did not reach
very high since the flood was detected only a few hours after it started,
but enough time to demo my unit and the adjacents.  Two dental chairs were
also damaged as their circuit boards were submersed.  Had to change the
boards and any foot pedals as well.

I fortunately have Marmoleum flooring with very little carpet.  The flood
happened on a sunday morning, so was able to dry out the carpet and clean up
so I could work the next day.  Only lost a halfday of one hygiene room as
the chair was repaired the next morning.  Restoration crew is working mostly
at night, changing dryway, etc.

A big headache, but for the most part, going smoothly.  Its amazing how many
patients don't even notice that the baseboards are gone.
