This winter the furnace quit in a old house, nobody was living there at the time. Anyway the pipes froze and the main water shutoff valve was turned off so that when the heat came back on there would not be a flood. Problem is the supply side shutoff valve did not shut off and there was a lot of water damage.
My question is can these valves be repaired or must they be replaced. Second question, are the fittings standard, this is an old house so the valve has been there for more than 40 years. I assume it has a coupling joint of some type.
Any advice would be appreciated. Thanks in advance
