The supervisor, when I asked him how much more 1" would cost than 3/4"
today said over $600! Hardly minimal. Maybe after they'd started the job
they figured they had me if I wanted to upgrade materials. At that
point, they could have gone 1" without losing any work:
They did the job today. I tried to get ahold of the supervisor before
they did any installation, but he didn't return my call. I had an
explicit understanding with him that they were to install 3/4" L both
underground and under the house. I talked with the foreman of the crew
and he wasn't aware of that, but I told him I had a clear understanding
with the supervisor. I also asked him about a bonding jumper at the
meter and he seemed to whiff on that one - didn't know what it was or
something. He talked about water heater! The supervisor didn't call me
back and after a while I go under the house and see that they installed
3/4" M under the house, counter to my agreement. I tell the foreman and
he says he's aware that he has to "rip it out." Why this has happened is
I hear him talking to the supervisor on his cell phone and ask to talk
to him. This is the same guy who the office was to have call me earlier.
I try to ask him how much more it will cost to install 1" than 3/4",
both would be L thickness. At this point, they were going to have to rip
out the hard copper under the house and hadn't installed any soft copper
outside, so there was no reason they couldn't do 1" instead. In either
case, they were going to have to wait for a truck to deliver the copper
they'd install. The supervisor said it would be over $600 extra! I asked
him why and he said the materials cost that much more. I said screw
that, basically. I call the office again (I'm not privy to the
supervisor's cell number), and he calls me right back and affirms that
1" costs that much more for materials and I say I don't want that and
they finish the installation this evening in the dark.
I have an idea that they never installed the bonding jumper, which I'm
going to try to check out tomorrow when it's light. I don't know what it
would look like. Would that be a strap between the copper pipe coming
into the meter and the pipe leaving it and going to the house?
