Years ago, a mechanic I trust said that hard coupled tanks
tend to rupture. So, the flex is necessary for safety.

The tank needs a low point drain. Might have one; one that's
not obvious.

Okay... I have to ask... What's with the stainless steel
exhaust
flex pipe and natural gas-type couplings going to the
reservoir tank?


That's not exhaust pipe, it's high pressure flex hose,
wire-reinforced.

One wants not to "hard couple" something that vibrates to
hard piping.

That's the proper way to do it.
