I know what you mean Gammel.
All vessels leak to some extent, or eventually, but particularly when the water pressure is so great in a deep or prolonged dive, even without battle damage. The sea is constantly trying to find a way in, and always will
Aces of the Deep used to simulate this, and the Chief would give you a warning that you can't maintain the depth as the pumps aren't keeping up with the ingress of bilge water. So in that scenario, you were faced with the choice of raising the boat and making it more vulnerable, or starting to go inexhorably down.
The same sort of dilemma does appear in SH3 because you can't pump or make repairs, or reload without making a noise.
The trick is, I guess, to time those activities and camouflage the noise with the next destroyer run, ie secure from silent running during the destroyer's approach and attack, and the minutes of asdic 'vacuum' thereafter. But then judge when to go quiet again.
Of course in an emergency, there's nothing you can do but pump and clank away, and hope for the best
It's yet one more thing to think about, which is great, but I don't actually know if the game is modelled to represent the accumulative leakage that comes naturally from being under water
