I want to change older hose bibbs to ball valve types. Current ones are sweat on and stubs are in brick-so very short. I'm thinking--sweat off the current then sweat on an adapter so I can use a screw on type valve. If I have regular 1/2 in pipe--does it make sense to use a 1/2 in to 3/4 in male? adapter then a 3/4 in (female) valve ? stronger fitting? Thanx for any advice on whats best and any help in not burning down the house-----Bob
