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. Basepump Model Gallons of Sump Water Removed per Hour. 10
