In Sgt.Peppers we use our lungs via the snorckel vale to exhaust 
a very light "vacum" of about 50 mbar as a pre dive check before 
the first dive of the day. 

The pilot exhaust air via the snorckel vale and close the ballvale. 
Than look on the barometer for a minute check to be sure not 
forget another ball vale or a seal is untight.  

Very quick and very cheap test to test hull integity.. 

Update Sgt.Peppers: 
Its now in the truck together with a self build overhead crane. 
Has now a central lifting hook.  

Update Euronaut: 
Shipbuilding 100%
Machinery     85%
Paint         30% (a company sponsors all the paint and the filler!)
Electric       5% 

Others:
Just found a two man seal (Seehund) sub from WWII with our sonar 
in the baltic. Crew is still on mission.

Also, it's the best way to install one of the big dome segment viewports! Grease the mating surface, have two or three people stand the thing in place, lean on it while the vacuum takes hold, and then install at your leisure (while running the pump continuously, of course).
