Any help in replacing my circulator on my 1970’s boiler would be appreciated. ie: draining and refilling the system (or does it fill itself through the main water supply), purging the system (I have no bleeders that I can see but it does have an expansion tank), and anything else that I might need to know I am a plumbing idiot when it comes to boilers. Thanks for any help!!!!!
Work on a Boiler improperly performed can have a very tragic result. Please consult a local licensed professional that can come out and advice you. If you have a question with the advice you get I am sure you will not have a problem getting second opinions on this site. Good Luck!
