Been having some seepage from the weep hole, posted on site as the replacement seat didn't seem to do the job. Today I pulled the pump cover to discover that the impeller was broken the center nut had broken loose from the rest of the impeller. This is the second time I've had this happen. When I replaced the seal I spun the impeller back on, figuring that the rotation of the pump shaft would likely tighten the impeller, evidently not. It appears that the nut backs off and as it unscrews grounds the blade s on the pump cover and this is the result. If you've experienced this I'd appreciate hearing your thoughts on it. Meanwhile since it's an 05 think I'll just go ahead and order all the seals, bearing, shaft and another impeller.
