I have a clack rt120 retention tank with the standard in/out head coming. It looks like the head has a threaded connection on top for a vacuum breaker that looks like a female NPT, but what size? What vacuum breakers do people use?
Also, is the bottom connection 3/4 or 1 iinch, the documentation is contradictory?
