Abstract:
1. A siphon break apparatus configured to substantially prevent a siphon effect in a fluid conduit configured to drain a fluid, the siphon break apparatus comprising: a first check valve in fluid communication with the fluid conduit and exposed to a pressure therein that fluctuates in response to the fluid flowing through the fluid conduit; and a second check valve in fluid communication with the first check valve and exposed to a second pressure between the second check valve and the first check valve, wherein the first check valve is configured to be substantially closed when the pressure increases as a result of the fluid being pumped through the fluid conduit, wherein the first check valve is configured to be substantially open when the pressure decreases as a result of the fluid no longer being pumped through the fluid conduit, wherein the second check valve is configured to be substantially closed when the second pressure increases, and wherein the second check valve is configured to be in a closed position when no fluid is flowing through the fluid conduit.
