steam system short cycling. Can I replace a vacuum breaker wit

mike cipollone_2

Dear Wall, This system cycles every 3-4 minutes from a cold start on Vaporstat. There are two vacuum breakers on the last part of the return within 5 feet of boiler. As soon as I remove the vacuum breakers, the unit ran without stopping. Can I replace the vacuum breakers with end of main vents? Mike Cipollone

Of course

those vac-breakers let air in, but not out! The air has to get out so the steam will distribute.

Is this a one-pipe or two-pipe system? The answer will help us determine what vents to use.

Steamhead, Hello, we met at The Eastern State Penitentiary last year with Dan. It is a two pipe system. Thanks, Mike
