I recently replaced my Jabsco Manual Pump, and afterward used the sump pump to drain the remaining water and soap (no solids) from the worksite. When the sump pump is engaged, it will very slowly drain the liquid, but when I disengage the switch, I get a large amount of backflow. First-time boat owner, so it might be something stupid. Can you guys walk me through trouble shooting and what my next steps should be this week?
Thanks again.
Thanks again.
