winterizing between water heater and bypass valves
I have a couple short water lines between the water heater bypass valves and water heater. The cold water line is about two inches long with a ninety degree fitting. The hot water line is about six inches long with ninety degree fitting. My question is is if there is a little water in these lines, will it have room to expand being its open right to water heater? What does everyone do if anything to these short two lines and fittings? I'm comfortable winterizing everything else, just don't want these little lines cracked.
