In fact, we feel we're possibly doing it *better* than a plumber might, at
least in terms of raw material. It seems to us (unsubstantiated opinion)
that a plumber might tend to maximize his *time* and not necessarily the
quality of the materials - unless specifically asked to by the homeowner
(who must correspondingly be willing to pay for the extra parts cost and
labor).

Bill is in his final shower as we speak. The gas is off.

Thee are some codes as to what materials can be used. I doubt your job will
be better.

We're waiting to hear the results though. Bill should have taken his
"first" hot shower hours ago.
