Pump Vaults

Stepros pump vaults house a high-head effluent pump that is used for pumping effluent from a septic tank or a dosing tank in a Septic Tank Effluent Pump (STEP) system. Pump vaults create a compartment inside an existing septic tank that can eliminate the need to install an additional pump tank. Each pump vault includes a filter that removes solids larger than 1/8″.

Benefits of Stepros pump vaults

  • Reduce maintenance time spent pulling and cleaning effluent pump filters.
  • Patented self-cleaning design and active filter flush expels accumulated solids from the filter chamber each time the pump runs.
  • Designed for easy installation and maintenance. Removable filter leaves pump and vault in place.
  • Effluent filter includes integrated removable float tree. Change floats without pulling the filter.

What makes Stepros pump vaults different from all other pump vaults?

Stepros pump vaults use a patented self-flushing design to prevent the build-up of solids on the filter. Each time the pump activates, a small amount of filtered effluent is pumped back to the filter chamber to flush out any solids. Less solids mean less maintenance and fewer service calls.

How do Stepros pump vaults work?

Solids are discharged away from the filter and back into the tank each time the pump discharges effluent.

Pump Filters

Stepros pump filters are designed for use with Stepros pump vaults. Filters feature an integrated removeable float tree which allows more room for the floats to move up and down. More room means fewer false alarms from floats hung in the “up” position.
