I need to install a pressure regulator on my incoming water service. It's currently over 100psi, and I have watering systems that require less than 80psi.
I need to cut into the existing pipe somewhere. I'm wondering how to do that. Since it's close to a wall I can't get a pipe cutter around it. Do I use a hack saw? If so, am I going to dump a bunch of copper shavings into the water lines? I'm wondering what that would do to appliances like a water softener and RO filter. Is there any special tool for cutting pipe with little clearance?
