How vacuum can form in a steam system

This line will dip down at some point to form a U-tube that will always have water in it. In the low point of that U-tube there will be a check valve that points toward the boiler. This line is there to equalize the natural vacuum that can form inside the supply mains and radiators during the fall and the spring when the pipes are cold on start-up.

Submarine depth ratingsWikipedia

The outside water pressure increases with depth and so the stresses on the hull also increase with depth. Each 10 metres (33 feet) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 feet), the hull is withstanding thirty atmospheres (30 bar, 441 psi, 3,000 kPa) of water pressure.
