The problems that come are the gas valves seats. If any debris (sand)
floating in the water gets caught under the seat of the valve, it could
prevent it from closing, opening or both. It also may damage a seat
designed to seal natural gas and cause permanent damage (gas leaking by the
seal at a small rate.) The water in the appliance pressure regulator also
plays havoc. The pressure regulator could become 'suggish' and may cause
further problems.

It sounds like a situation that occurred in Toronto Canada a number of
years
ago. A gas company (I worked for the gas company, this is how I heard
about
it) was tapping an old cast iron gas main for a new street line. It was
beside an old cast iron water main and looked identical. They apparently
look for condensation on the water main to tell it from the gas main.
However, they tapped the wrong main and sent city pressure water up the
small street's gas line. People were angry when water poured out through
all
their gas appliances and flooded their basements. It cost the gas company
lots to make it all right.

In Baltimore a few days ago, water from the city water supply leaked
into gas lines, and it apparently damaged some gas appliances. (Not
mine.)

Any idea how water in a gas pipe would damage a stove or other
appliance? Maybe I'm still living in the 50's but I would think one
just takes the burners out of the stove and lets them dry, and the gas
company could do whatever it does to get the water out of the gas
lines. Force hot dry air through the lines? Or just regular air if
that is too hard.
