After the winter and not using heat for 3 weeks, should I completely drain the boiler and piping?

    Does your boiler use steam for the radiators or does it use water and a circulator pump?

    No in either case but some extra stuff for the steam boiler might be a good idea. If you are not sure than post a photo of the boiler and we will know.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Yes it is a steam radiotor system. I treat the water in the boiler during the heating season.

    IF you think you have a lot of sludge in the bottom, there'd be no harm to blowing that down — but then refill it and run it to full song to get the oxygen out of the water. Otherwise leave it alone.

    If you treat the water, there shouldn't be hardly any mud in there. Drain off like a quart max and see how it looks. If it starts to flow pretty clear there's no sense draining any more IMO. I'm in full agreement with Jamie's "leave it alone" advice!

    Out of curiosity, what is your treatment methodology?

    No. The insides of the boiler will remain moist for many weeks.

    I just read that article. So, he was saying to remove the water in a steam boiler? Ours sits unused all summer. I always thought it should be left alone.

    I would leave it alone.

    Did you ever take a creative writing class? Your writing style is entertaining while drawing the reader in. I guessed years ago that you were the author of Zoning Made Easy, and you verified that a few years ago on this forum. It's an excellent style that I have shared with many students in the past.

    Thanks! I never took a class, but I’ve read a lot of books, mostly novels. I have a huge collection of brief descriptions that inspire me. For example:

    He had the attention of a hummingbird

    A yacht of a nose

    As quiet as greased smoke

    I have never understood the two of you. She’s a steaknife, and you’re a dessert spoon.

    She ended the conversation with the efficiency of a guillotine.

    She looked at me the way a woman looks at a pair of shoes that are OK, but not quite right.

    Her eyes were clover green and Celtic fierce. 

    He picked his words as though they were fruit on a bramble bush. 

    As hot as a Tex-Mex picnic on Mercury 

    He entered the room looking like a Spanish galleon in full sail. 

    He left like a creaking rocking chair, squeaking and leaning back-and-forth.

    He was charismatically challenged.

    As crazy as a soup sandwich

    He kept smiling at her with a mouth like a wet keyhole.
