Replace drain valve on old style horizontal expansion tank with ball valve?
I have a hot water system with old style horizontal expansion tank in the basement ceiling rafters above the furnace/boiler. The drain valve on the expansion tank is dripping from the outlet (not from the bonnet/valve stem).
I don't think this is a special valve that allows air to get in while the tank is draining, it seems like a standard gate valve. In my opinion, gate valves tend to leak, so I was thinking of replacing the gate valve with a ball valve.
Or, I can replace just the washer in the existing valve. Any opinions or recommendations?
