Nice to hear you have had the problem resolved – you will appreciate the difficulty we have in answering questions in this medium when we are not aware of all of the facts – ie the motor running continually on your pump. Now you have the problem repaired you will also save significant $$$$ on your electric bill as the new pump will only operate when it has to instead of running all the time.
As for the repair price I beleive it is reasonable and not excessive.
