All house boilers shall be constructed with one or more air holes near the top of the inlet pipe and sufficiently strong to bear the pressure of the atmosphere under vacuum. The stop cocks and other appurtenances must be sufficiently strong to bear the pressure and run off the water in the mains. All persons taking water shall keep their own service pipes, stop cocks and apparatus in good repair and protect them from frost at their own expense and shall prevent all unnecessary waste of water.
