[VAC] Re: water pump again
This doesn't make sense to me unless the water heater is equipped with a
backflow preventer. It seems to me an air cushion anywhere would pressurize
the whole system but if it is in or beyond the water heater it might push
hot water back into the cold water lines when a cold water faucet is opened.
Can someone clarify this?
