thanks. i am most definitely not the guy working on it! i don't have any idea how to do this stuff, nor the inclination to learn. the plumber brought the new heater over on wed, he's supposed to come back today and install it.
my mom's sage advice: "write the check and carry on".
He may or may not do it,,,, but if your old heater was one where the dip tube did disentrigate you will get little bits of black, what looks like dirt, in your faucet strainers. So if you have faucets with aireators on the end. Remove them and clean them out. Depending on how bad it was you might get a a little smoother flow.... same with shower heads.
