Is it OK to dump the laundry water discharge into the sump pit?
Most sump pumps are designed for clear, clean ground water. The chemicals in laundry discharge can attack the seals on a sump pump. It’s possible for lint and other things discharged to get stuck in the impeller area and jam up the pump. Additionally, the soap scum that can be left behind from laundry water can foul the switch – this is particularly true of vertical switches. We recommend you purchase an effluent pump if you need to pump out laundry water.
