Get out your checkbook. Figure between $350-450 for a plumber to replace a circulator,(parts+labor) if that is in fact all that's wrong. -- ~Help Find a Cure for Cancer~ ~Proud Member of Team Discovery ~
Once you do get it replaced, if the pump and/or motor has oil holes, make sure it gets oiled as necessary (according to pump/motor manufacturers recommendations). Most quality recirc pumps that I've seen do have oil holes.
If you pay someone to have your boiler system serviced on a regular basis, watch them and make sure they lubricate. It is an often overlooked but important maintenance item that will help pumps and motors last a very long time.
It was not the pump- it was a type of motor. Told me the system was old and it was difficult to get Replacement parts- that I will be needing a new one soon. Asked him to oil. I did not know where the oil went- stared right up. Hopefully it will last a couple of years. Next question 1200 sq feet house -one story - crawl space- should I scrap the boiler when I replace???? I was told 5000 for a new boiler ( to bring it up to code) or 8000 for furnace???
