Worn components can cause leaks in the form of small, steady streams or drips.

How long does it take to bleed air out of water pipes?

How does air get into a hot water heating system?

During fill or back flush hydronic system operations, city or well water enters the system. Water has compressed air in it. As the water flows through the system, the air settles in to high spots. Over time the resulting air pockets reduce the efficiency of the hydronic heating system and create noise in the pipes.
