I live in an old house… There’s a brass hot water pipe that runs from the hot water boiler to a tap, and there’s no vavle between the boiler and the tap. I want to remove the tap and cut off the water supply permanently. To do this, I want to install a plug into one of the unions along the way.
The question is this. How do I unscrew a pipe that’s threaded into a union? There’s nothing to grab on to. Is there a special tool I need to get that will allow me to grip the bare pipe and twist it?
Why not cut off the pipe right at the water heater and plug it off at the source?
To remove a brass pipe without and outside thread I use an “easyout” tool that bites into the internal portion of the pipe to be removed when turned in an anti clockwise direction thus removing the pipe or fitting without making contact with the outside of the pipe or fitting to be removed.
