I am replacing some old gate valves in my household plumbing with new ball
I am using valves with threaded fittings, and a union on the downstream
My question is, how can I solder the threaded male fitting to the copper
so that the valve handle will be lined up the way I want it after I tighten
the supply pipe? I need to tighten the valve until the joint stops leaking,
handle is invariably not where I want it.
