Sorry if this is a duplicate, my last post didn't take.

The plumber showed me what he pulled out and said it wasn't type L.
He showed me Type L and told me it had a thicker wall. The old stuff
appeared to be thinner. So I don't know if he was snowing me.

I was also considering either 1) building an extention of the laundry
room and moving my water heater over there or 2) getting a tankless
heater over ther (inside or outside unit). It would mean eliminating
those two runs of waterline, though I'd need to run a gas line about
20 ft from the meter. These could be cheaper in the long run.

The plumber and owner don't seem to like PEX. Is it harder to deal
with? I mean, this is not a small outfit.
