I want to solder new faucet in, but not licensed-need ur help professional plumbers?

Question

I have extreme experience in plumbing, among other trades and I want to install a new shower faucet and such, but the apartment wont' let me cause I dont' hold a license in this state,

Since this is an condo I never encountered this. I got the hotwater figured out, question is the main cold supply. But is there some way around this?? perhaps i could cut the pipe, then quickly attach a compression shutoff supply then go from there. I would think this would be an idea, I'm going to test this theory with another supply with a shutoff before I attempt but main importance is homeowners dont' care, and are really fustrated that about the situation, and said if i can get aroudn it to do it, They own the condo, and it should be their right to do it.
So any suggestions from professional plumbers?

Yep thats right, years of experience, over 14 to be exact, electrical, plumbing hvac, roofing, new homes, additions remodeling, foundations,
Now im experienced as in own a "sucessfull" company, I do all trades therefore am not master of none. I know plumbing many roughins many many remodels, jacuzzis, sunken and surface, copper sweating no problem,
So in saying this, Its a condo, as in you have to jump through hoops, I am out of state, visiting family. They want their bathroom remodeled, All I need is the water off for 5 minutes, to solder a shutoff on there, But they want a licensed plumber. NOW...If I didnt' know what I was doing then ok, perhaps, but only hold back is fact that they want that paper, Where Im at they wants $350 just to come out. And the reason im in a hurry is because I need to get back to my state so I can continue my companys business.
Now I have always been able to shut off water everywhere I been, this is new to me. Just looking for solutions

the reason im doing this is for family, I can't shut the water off cause its a condo with shared water. I think this is stupid, but Im not from this state.

Answer 1

Shark bite fittings can go on quickly , no solder and easy to work with.
There is a freeze system that freezes two places on the pipe so you can cut into it to repair or (in your case ) modify .This may somewhat hard to find at a rental place.

Best bet is to use the shark bite set up ready to go and turn off the water cut and slap it together and turn the water back on maybe 10 minutes of the water being off.

They may want the "license" for the bond
with the freeze system you don't have to turn off the water as it is frozen inside the pipe and therefore plugged

Answer 2

Be carefull with shark bite fittings.
They are simply just a o ring with a little metal ring that grabs the pipe.
I have seen shark bite fittings leak for various reasons.
A true professional plumber only uses shark bite as a "temporary" fix.
Call a plumber, it will only cost a couple of hundred dollars, and will be worth the investment, over what may happen in the wall a couple of months down the road, when you have to explain to the condo association why you flooded the building by trying to save a buck.
Good Luck

Answer 3

You say your experienced then why would you want to do this, what's the hurry with a compression fitting, this doesn't even sound right.

Why not just turn the water off and cut the pipe, and then solder a new fitting on?

Why are you doing all this to start with?
