Hi,

A plumber told me that it's a good idea to shut off water from the
washer when it's not in use because the flexible lines aren't rated to
continuous pressure.

Well, they ARE rated for continuous pressure, but do break. So shutting off
the water is a fail-safe idea. Special valves are available for just that
purpose - to make it easy to turn off the water.


A. Is that true?
B. Does the same apply to the gas line for the dryer?

It does NOT apply to the dryer's gas line (unless you're using the push-on
rubber hoses that have been outlawed since about 1950).
