Sounds excellent and the water is easy to dispose of when you're done (as long as you're not too 'green').
Buy before anyone thinks this is a full alternative to vacuum bagging, be aware that vacuum pumps achieve vacuums in the high 90s % and that is over 14 psi of pressure - equivalent to over 30 feet of water depth and so a bit deeper than most water beds......
You can see why people use vacuum pumps when they can generate this sort of force, eh?
