Foreign Object in Boiler

Short story - I accidentally got a 12" piece of thin string inside the boiler. Should I purge the whole system ASAP or can I wait a few months until I do it for the spring shutdown?

Longer version - I work anti-corrosion tablets into the boiler via the skim port. For several years I have been doing this via flexible shaft gripper. But to work around the right angle of the skim port I tie a piece of bank-line (string) around one of the prongs and tug it to work the shaft around the corner. It always works. But today was the first time I ever pulled the shaft back without the string on it.

I skimmed a bit to see if it would float out but it did not. Have I screwed up my system? Is it going to get into the LWCO and ruin it?

    Don't fuss. It shouldn't hurt anything.

    If it is not floating on top (since it did not skim off) then it is most likely on the bottom and will probably stay there. Normal maintenance of the LWCO (Weekly flushing) will let you know if it gets in there. As long as you keep up on the proper maintenance you would be fine.

    Or you can take @Jamie Hall's advice too

    Why are you trying to play with string near a boiler anyway? Trying to fly a steam-powered kite?
