problems with purge boiler

My basement and 3rd floor heating stop deliver heat. I first try to bleed those pipes, no water come out. I thought this mean there is a airlock and move on to purge pipes using street pressure by bypassing feeder. Water and bubbles start to come out between 25-30 psi. However, I let the water run for more than 10 gal, and bubbles are still come out and problem cannot be solved.
Any clue?

I always bleed the system with the circulator pump running.

If that works for you then fine... but understand that the only 'right' way is the way that works. Different situations call for different methods.

You probably have no pressure in the system is my guess. If nothing comes out... well, how can NOTHING come out?

Go to the boiler and tell us the readings on the pressure and temperature gauge.

Know that boiler gauges are lying pieces of doo-doo.

Read this:

And because after you get the pressure in line where it needs to be, you will probably be complaining that your pressure relief valve is now spewing, also read this:

If you have the steel tank in the joists above the boiler, let us know, the instructions are different.
