1stly do you have valves in your circuit?? youu can close them and work then re-open them . obviously you would have thought of that.
if you can use a clamp saddle on the pipe (usually for steep pipes) , use a piece of polypipe, connect the other smaller pipe to the polypipe then just add it to the circuit using simple connections (no glueing required) . but this seems to be some kind of unprofessional work. so don't let your consultant see this ...
otherwise i don't see much alternatives to draining the line. cut, braze and re-open the line...
can anyone else enlighten us?
