Parts and labor are not broken out but the invoice says $336.00 for the
faucet installation and $146.00 for the shutoff valve installation.

If the labor was $336, yes it sure seems high.

Seems high? That's forcible rape. I can do one of those in an hour if the
old one is hard to take off. And another hour for the shut off valve even
if I have to sweat it on. I'd say $166 an hour is high. I only charge $80
for what I do.
