  • Drain & condensate: compact drain pumps and condensate pumps for HVAC and appliances
  • Basins & panels: pre-assembled packages, basins/lids, float switches, alarms, and control panels

Quick choosing guide

  1. Define the job: sump/effluent (clear/gray water), sewage (toilet waste), or grinder/macerating when you need to pump farther, higher, or through smaller pipe.
  2. Size for flow & head: match GPM and total dynamic head; review the pump curve for your model.
  3. Pick the system style: pre-assembled basin packages speed installs; add a high-water alarm to every pit.
  4. Choose protection: add a battery or water-powered back-up for outages and a NightEye® smart alarm for remote alerts.
  5. For new baths/retrofits: use Ascent™ II macerating systems; for in-pit grinding, choose a ProVore® grinder package.

Pro tips: Use a check valve on every discharge, drill a weep hole on sump installs per the manual, and set floats clear of cords and walls. Seal basin lids, add a high-water alarm, and test back-up systems monthly. For grinders/macerators, follow venting and branch tie-in diagrams and size circuits per HP. Questions? Share head height, pipe run, and amperage—we’ll build a dialed-in Liberty package.
