Water hammer, when the liquid slams to a stop when a valve suddenly closes. It can burst piping.

And did so in spaceflight. The N1 was a victim of this.

Funny how it sounds when the RCS fire.
Remindes my of the tubing of the central-heating at my home when a valve is closed to quick and causes "a backslash" (if that's the right term)
...and Yes, there is some air-pockets in the system that should not be there (in my central-heating I mean)

"Ist bei Ihnen schon ein Schnüffelstück gesetzt wurden?"

Spoiler: Northern German Regional Humor Warning

In englisch language it just means "Was already an automatic deaerator valve installed in your house?"

ADG Valve

epuis 1984, ADG Conçoit et commercialise des gammes complètes de robinetteries et de raccords pour les secteurs d'activités très diversifiés : industrie, bâtiment, chauffage, irrigation, adduction d'eau ...

www.adgvalve.com

Which here is plainly called "Schnüffelstück" ("Sniffing piece")

Just watch this and was impressed. 20 launches per mission never work

Really, really good (and fun) video, not kind to the Artemis architecture, and effectively, its management.

The number of launches needed for a single mission...

I knew that term, but that's a bit to violent - so I didn't use that. If it was water-hammer I would be very concerned
I even built a "demonstrator" with plastic pipes once, to demonstrate that effect to youngsters that thought "close the valve as quickly as possible" was a smart idea

Reality slowly converging on what this video mentioned...
