Noise in bathroom !!

[Watermelon97]

Recently moved in to a new build and all night I’ve been hearing a whirring noise from the bathroom. It sounds like the extractor fan but it’s switched off on the wall and if I press it on it turns on fine. What could this noise be?!

Neighbours extractor Fan?

Trapped air in pipes?

Sounds better than what I heard coming from our bathroom at 3:10am.

The eldest must have had a mad one last night.

Do you have a toothbrush/shaver socket? We find ours makes a noise with some types of chargers but not all 🤔

Ours does this, I think it's just the wind getting in and spinning the fan.

Do you have an extractor over your hob? Might that have been left on?

If it is a new build house does it have 'whole house ventilation' with a unit in the loft?

You could try turning your electricity off for a couple of minutes and see if the noise stops. ( may be a bit of nuisance having to reset clocks etc.) Just to see if it is your house or the neighbours or wind.

Ghost using your electric toothbrush?

Extractor fan. Check the manual and adjust it.

I had this: turned out it was my battery shaver left switched on, buried in a drawer. The sound appeared to be coming from the wall, we even got an electrician in and it took him a while to discover the cause 😬
