[ZOA NOM]

I did the work myself (sweating copper is a PITA, but not rocket science) during a remodel, and had the inspectors sign it off before the drywall went up. Total cost was under $500, mostly due to the layout. Two bathrooms and the kitchen share two walls, so I only need to run the two 3/4" trunks into the attic from the garage, and then run the 1/2" feeders down the walls to the showers, sinks, etc.
