Installing a single control valve won't prevent anything. You need to
turn valves off each time you finish using the washing machine. If you

I don't know how you were raised, but it is much easier
to turn off one valve with a touch of the finger than it
is to turn off 2 valves taking several stiff rotations.

I just installed a dual toggle valve and, while I don't
always remember to turn it off, I do the majority of the
time.
