Water Pump/Central heating

[bloomingflower]

Hi Everyone

Not sure if this is the right place to post lol

As its now getting a bit nippy I have switched the central heating to come on twice a day.. morning and evening.


Have just noticed a funny deep humming noise/sound coming from the water pump. This has never happened before and have been in the house for 8 years without it going wrong. Which is not bad for that length of time. But I expect it will need to be looked at a.s.a.p as am really worried about that sound. I have called the repairs dept and reported it, and have said it is an urgent job (if it is a repair job). The normal waiting timescale for a repair to be looked at is 28 days.

Has anyone got any suggestions what that humming noise is?

Probably air in the pipes cause a vibration and hence a humming sound ....best way to clear it is to shut off the water at the mains run everything to empty then turn it back on again.

Says I the plumber lol - seriously I know bugger all just thats what happened in my old house when we put the heating on again after the summer. We had a back boiler.

Hi BF

I assume you are living in rented council property and the owness for repairs lies with them.

The 'humming' noise is likely to be the pump bearing, if you have not had the heating/pump running for some time it could just be that the noise is only temporary and may subside after a couple days running. However, if the noise continues or indeed gets worse then I suspect the bearing has become defective and will need a replacement pump. If the council are responsible for maintenance on your property there is little to worry about as they are obliged to fit a new one.

If it's a combi boiler, to me it sounds like the water level needs topping up. there should be a gague with a minimum water pressure level. This can be topped up if it is low. There should be a filler valve. Get your other half to open the valve whilst you watch the gague, when that shows past the minimum level switch it off. Then bleed each of the rads with a bleeder tap, to release any air. Redo the gague bit again because the pressure level would have dropped again and your problem should be solved.

p.s. I did my apprenticeship with British Gas some 20+ years ago.

Good luck with your mission.

Hi Thankyou peeps for all your advice. I will deffo try all the troubleshooting ideas and give them a go.. I was really worried.
My o/h had a sneaky feeling it might be air in the rads/pipes, but wasn't sure.

That noise startled us and never heard it before and thought it was gonna blow up or something lol

Thankyou once again.. you have deffo put our mind at rest.

Re: Water Pump/Central heating

My pump has a "valve" which you open with a coin while its running to let air out-- until water runs out-then you tighten it back up again with the coin.
