In an existing house, when a new water heater is installed, should an in-sight or lockable disconnect also be installed if one was not available before?

Thanks

It was a requirement for the original one and is still a requirement, so the answer is yes.

Yep. Haste makes waste and my memory ain't what it used to be and as my Doc says, "getting old is not for sissys."
