This is something that nags at me whenever I install a gate valve.
If I have a 3/4" copper supply that goes into a gate valve the valve body cuts the pipe ID in half (or more).
Why isn't there a drop in supply pressure on the outgoing side of the valve?
Or is it that the difference isn't obvious?
If it is that the difference is not obvious then why do I need 3/4" when the valve is only allowing 1/2" at best to pass thru it (don't add a 1/2" gate valve into the discussion) ?
Or is this just why I like ball valves?
