Seems a shame that Roger has just got it going when the weather is so mild that we hardly need any heating Eh malc?

Oh dear. I think your new pump, even on the lowast setting, is too powerful for the F/E tank and vent. Before you start, I'd bleed all the rad's in case any air in them is being compessed by the new pump. If it is, when the pump stops the air will expand and the easiest path for the water to go is back up the vent. If you bleed the rads, this can't happen.

I think that you're on the money, there. Capped the vent pipe and then turned the pump off. The water in the header tank gradually rose by virtue of it coming back up the feed pipe. So I agree that it has to be air in the system compressing. Trouble is that some of those rads refuse to bleed very well. I have those useless Aladdin self-bleeding valves wich are about as much use as a chocolate teapot. I do have some propoer ones but with everything else higher priority guess that fitting them will have to wait.
So it looks as if I have my own 'pressurised' system now as I've turned off the feed from the header tank and any air in the rads or pipes are my own expanson vessel. The other advantage is that when the pump turns on. it's a damn sight quieter.

Me know if you struggle as we had that issue when we first moved in and Jenx from the original Haven wrote me instructions for how to sort it.
If it’s anything like mine you have to bleed the oil through by removing the oil feed pipe...

Got to get some oil first ! Just got back from a bit of ditch digging to try and get the water from off the hill. Freezes something rotten and we're running out of grit ! And the hill will need gritting for the oi tanker to get up it.
