I am really not getting the connection between draining the h/w tank

when I get a plumber out here.


Rare, but not unheard of:

Turning the main valve on rather quickly puts a pressure surge in the
pipes.
If a joint or section of pipe was fragile, this sudden surge could
cause a
failure.

Just jostling a section of fragile pipe can cause leaking. This
confirms my
decision to search high and low for a new cartridge for my kitchen sink
instead of replacing the whole assembly. Old plumbing is vengeful.
Bother
it enough and it will fight back. Hard.

I learned that putting a new toilet in. Everything up the line from
what I
was working on failed because the joints were old, calcified and ready
to
go. And they went. A simple toilet replacement ended up with torn up
walls, multiple trips to the plumbing supply house and visits to the
neighbors to use their toilets. I did learn that if you're going to be
applying any serious force to an old pipe to strap it down as well as
you
can to eliminate the chance of it acting as a huge lever and damaging a
joint upstream.

Same damn thing happened when the shower diverter valve failed. After
70
years stuff happens.

Hi,
It's like being charged with man slaughter running over already dead body.

Reminds me of the law school hypothetical about the woman who shoots a
shotgun out the window and miraculously hits her husband, who had just
jumped off the15th story roof and was en route to the concrete below and
certain death. The coroner says the blast killed him and he was dead by the
time he hit the ground. Was it manslaughter or suicide?

(How does this relate to AHR? She probably shot him after he nursed one too
many leaky galvanized joints beyond their useful lifetime.)
