Both end station pumps running smoothly. The corner station pump (1194) must have over heated and kicked the breaker. One of the felt filters disentigrated and clogged the filter/muffler. This was cleaned out and put back together. A newer felt filter was added. The graphite veins seemed to be in fair condition. Pump 1194 was put back into service. I will check to see if it continues to run smoothly this after noon. More rebuild kits need to be ordered.
