It appears to be leaking underneath right along the line where the seal plate attaches to the pump (where red arrow is pointing). I looked under and could see several water drops along the bottom of this area where the seal plate bolts up against the pump (where red arrow is pointing). I installed a brand new shaft seal when I rebuilt the pump. I kept the old seal plate gasket because it appeared to be in good shape and fit in the grooves. Do you guys think that maybe the seal plate gasket came out of the grooves when I tightened down those bolts? Wouldn't it be leaking more under the MOTOR if it were the shaft seal? I don't see any water under the motor area, just dripping along the seal plate bottom. Maybe I tightened the bolts down a little too much causing the gasket to shift (although I only went a 1/4 turn past hand tight)? You can actually see where the slab is wet underneath the pump/seal plate area. What should I do to attempt to fix this? At least the pump is running good now.
