Liberty Pro Series Sewage Ejectors

QuickTree™ on Liberty Pro-Series sewage ejectors allows easy inspection and replacement of the pump and/or alarm float without disconnecting plumbing or removing the pump itself. Floats are mounted on a stainless steel rod (tree) and suspended in the system by means of a holder built into the main cover. A secondary “access” cover on the lid easily allows service access to the switch and pump. To protect the system during rough in and masonry work, the new Pro-Series are shipped with a clear disposable construction cover. This recyclable cover is simply snapped in place and can be easily removed when the system is ready for finish plumbing.
