Why is my sight glass so dirty?

When you flush the boiler you are only cleaning a portion of the whole heating system. You may want to try a steam clean such as Squick to clean up the system.

    Why is my sight glass so dirty?

    I regularly drain the furnace water and also the returns but the bottom third of my sight glass is very dirty even when the water I drain is clear. Any answers and a possible solution would be great. Thanks

    Does the water in the glass jump a lot it could be that it is oil on top of the boiler water, you probably need a pro to skim the boiler.Any oil and dirt on top makes it hard for the steam to break through.

    Pat, it may be necessary

    to power-flush that boiler. There is probably a considerable amount of dirt and sludge on the bottom of the boiler. Simply draining it probably won't get rid of all the dirt.

    This is a job for a pro.
