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.

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

Many thanks in advance!

Aaron

Why not? Hoses fail regardless of their rating. Ever hear of water hammer?
Every time you turn off your faucet there is some transient pressure spike
in your system. At some point in time there is always the potential of a
hose failure after it has been subjected to (weakened by) these high
pressure pulses. Get yourself a single lever Watts valve. Gas line is
under low pressure but what's the harm in shutting off the supply to the
dryer/ I have a ball type valve in the line right next to the dryer.
