You're welcome of course.
Maybe this idea is useful to you: Consider a section thru the pipe wall at any arbitrary distance from a capped end.
The end force is acting to separate the wall either side of the section. This force is resisted by the wall itself.
So, your system is open to the atmosphere? Then by all means disregard hydrostatic end force, there isn't any.
But every pressure system of any use is not open to atmosphere.

Just watched the latest Maximus Av video on the water leak. I don't know how credible the guy is but he does not know the meaning of "potable water'. See 2:37 in the vid.
A clarification: A diaphram closure does not typically use a gasket. The diaphram is seal welded to the channel flange. That is why the cover is beveled as shown. Partial bolting is installed. Weld as accessible, move the bolting, repeat till completed.

Cleared cache & browsing data, seems to have fixed it.
That was weird, I was in the middle of posting a reply when the format just flipped from one to the other...
