Bleeding Pump - Is This Right?

[youdontwanttodoitlikethat]

Just moved house. My conventional open vented heating system has the pump on a vertical pipe just below the boiler.

I drained down to replace a couple of radiators. When I refilled, I bled the Grundfoss pump. I have never bled a pump before, and when I loosened and removed the bleed screw, I expected to hear a bit of air escaping like the radiators, followed by a small jet of water.

All I got was a slow drip (with the screw removed), about a small drop of water every 15 seconds or so. Is this normal, or is there a problem with the pump? How should a pump bleed go, as I say, I've never had any experience of doing one?

You have done the job correctly, if there was air in the pump you would have heard it hiss out and spit a bit, a steady drip indicates that the pump is full and no air exists time for a cuppa!

Thanks Boilerman. After moving house, and trying to sort out a basically sound ch system that needed a couple of new rads, I'm relieved that I can now
A) Stop spending
B) Get 'She Who Must Be Obeyed' off my back for a while

I just imagined I would get a jet of water from the pump bleed, similar to what you get from a rad. You've set my mind at rest.

Time for a tea and a large JD!
