Hi
I'm neither a plumber nor even really a DIY person, but I could use some help. This evening I bled the upstairs radiators in our house and shortly afterwards, the central heating pump (a Grundfos Selectric UPS 15/50) began making a sort of rhythmic thrumming noise with occasional loud 'coughs'. It also started to get very hot.
I immediately turned off the central heating and hot water and after a while the pump stopped. I initially assumed that the noises meant that the pump was dying but then found one or two web forums saying that my bleeding the rads might have circulated some air/gunk into the pump itself and that I ought to bleed the pump with the big silver screw at its centre. I did this, but no air or water came out so I fastened it back up.
I now don't know what to do. I don't want to call out a plumber for ridiculous emergency charges and I don't have any faith in my own ability not to flood the house if I start messing around with the plumbing. A replacement pump looks about £65 online. The problem is that I do have a 16-month old baby in the house and it looks like being another cold night. Should I worry about pipes freezing or anything? Should I turn the heating back on in a bit and see if the problem is still there? Is there any risk of fire or electric shock? Any advice would be welcome.
Cheers
