new pump replaced by British Gas

[manorpurl]

Hi all,
my pump got burnt out so BG came and replaced it. But now the pump is making some crackling noises as if some water is passing through it with air. Also some rads make bubbling noises. The pump is brand new and the engineer replaced it. Any ideas as to what is going on here? I think it might be air, but how do i get rid of it. Any clever tips.
Thank you

hi doesnt the auto air valve dispell air at the pump? the little dust cap on top should be slackend off a little, as for air in the rads as air goes into the rad it should rise to the top of the rads so it can be bled out , just my thoughts on it but i would call em back out
