I have a pipe in the basement with a Gate Valve that isolates the sprinkler system. I just closed it for sprinkler system winterization, and noticed that it is not shutting off 100% the water. I looked at my local Home Depot for a replacement, and all I could find is a ball valve with the same rating. I have attached a picture of the specs of the original valve, and of the one I found in the store. Is there any contraindication to use a ball valve instead of a gate valve? Also is there any way to refurbish a gate valve?
