Pool Pump Timer Error

The timer tabs on the pool pump clock loosened yesterday allowing the pump to run for several hours longer than normal before I noticed it.  The pump being one of our greatest users of electricity is normal restricted to four hours maximum in the winter.  We also ran our irrigation pump during the previous 24 hour period.  But, doing all of that and with very overcast skies we managed to generate 25 percent of our energy from solar.  The temperatures were around 80 F and the air conditioning did run some but not nearly as much as in the summer.
