I disconnected the pump from the pool. I then disassembled the pump housing and replaced the shaft seal. In order to access the seal you must remove the impeller. I decided to replace the impeller with a new one. Once done the replacement I then reassembled the pump and reconnected it to the pool. It works perfect.
