- Q.I am doing renovation in a
house that was flooded. Is it necessary to replace
electrical receptacles that were under water?
responds: Just because they got wet from fresh
water doesn’t automatically mean they are
doomed (if it was salt water, replace them). In a
fogged-up bath, the receptacles are also getting
wet all the time. It all comes down to a matter of
corrosion. Turn off the power and take a few of the
receptacles out and look at them. If there are
signs of corrosion, you should replace them. Any
corrosion that you can see would indicate that
there might be corrosion on the internal contacts,
which you can’t see. This corrosion will
act as a semiconductor and create heat, which will
destroy the receptacle and the male
If the receptacles in question are the standard
cheap hardware-store variety that I see in most
buildings, I would replace them with high-quality
commercial-grade ones — perhaps higher on
the wall in case the room floods again.
