I recently installed a Rule LP900 manual bilge pump with a float switch, and all ran well, other than I noticed some fine jets of water escaping around the seal where the pump locks into the pump body. I wasn't too concerned, but more recently it was operating and I saw water burst through the top of the intake nozzle. Now, some water entering the intake escapes through the holes in the top back into the bilge. I cannot find any product information relating to this. Has anyone encountered this before?
