Sewer backup and boiler increase

i have a sewer backup and i believe it's causing my boiler to fill with water, could this be related? i recently drained my boiler for the summer since this is what my boiler manual says so it surprised me to see the sight glass filled. Nonetheless i have a plumber coming to snake out the sewer now but should i mention the issue with the boiler or is it not connected

    Only if it is leaking in to a buried wet return. More likely that the valve isn't holding.

    Water doesn't run up hill -- so unless your sewer line is higher than the boiler, it can't be the source.

    Or the lowest drain is above the boiler and it is backed up to above the boiler, but it is very unlikely that the pressure would go from one to the other. Unless the thing perceived as a backup is actually a wet return leak and the boiler valve is not holding.

    I'm assuming you have a steam system, is so I must ask does the house smell like baked excrement when the boiler runs?
