Basepump RB750-AVB with Back-flow Prevention Vacuum Breaker

This is a water powered back-up sump pump. It eliminates some risks that a battery powered pump has, plus you don't need to replace batteries every several years. It runs off of your city water supply, and draws one gallon of water from your supply for every two it pulls out of your sump, then dumps all three outside of your house.

Most states and municipalities require that you protect the potable water supply from any possible cross contamination, whether it's likely to happen or not. These are connections that could cause potable water to be contacted by non-potable water, like sump water. All standard models of Basepump are designed to prevent that from happening, but some authorities require a separate "approved" device be installed to protect the water supply. In these cases, the solution has been to install either a dual check valve or a Reduced Pressure Zone (RPZ) device to accomplish this. The RPZ device will restrict water flow and in many cases prevent a water powered system from operating. It is expensive, requires an annual inspection by a certified technician using special equipment, and must be reported to the plumbing authority in your municipality. Most municipalities recognize Atmospheric Vacuum Breaker (AVB) devices. Other water powered backup sump pump designs cannot use them, but Basepump can. Because of its location on the ceiling, it has the necessary height to prevent water from backing into the potable water supply. It simply cannot happen if installed properly. Once installed, inspected, and approved there should be no further question about it's safety. This makes it possible to meet the codes and also keep the costs down. Always check with your local plumbing department if you have any questions.
