Hi,
I've been having an annoying problem of humming pipes in a house. I've outlined the details below, I've had a plumber round who suggested they couldn't help without hearing the noise, however it isn't constant and mainly comes at night so this is proving impossible. Any advice would be greatly appreciated as I'm pretty much at a loss.
Combi boiler system in a house. Gloworm betacom2 24
Humming sound coming from pipes. Starts as an intermittent hum then builds to a solid tone that gets very loud, then fades off. Repeats.
The sound is loudest and seems to come from the wall by the bedroom door. The boiler is in the kitchen downstairs the only pipes I can imagine being in or near the wall are heating as the bathroom is further away. The boiler doesn't make the sound only the wall.
It's been coming and going for weeks, it mainly makes noise at night but also it happens in the evening and during the day sometimes.
It makes the noise when the heating is on and when it's off.
I've tried bleeding the radiators and adjusting the mains water pressure (I wasn't sure if it was the water or heating at first) but seeing where the sound comes from I'm guessing it's the heating.
The radiators in the upstairs bathroom and the airing cupboard both seem to gather a lot of air, I've been bleeding them every week and each time the airing cupboard radiator has had air in it. I'm guessing there's a leak or air getting into the system?
The boiler pressure cold was originally at 1.5. I've bled the radiators and topped the pressure up before, didn't have any effect. I think the pressure is down to about 1.3 now as I've been bleeding the airing cupboard and bathroom radiator.
There are 3 radiators I can't bleed, the downstairs hall, the bedroom and the spare room. The valves are worn and rounded and keys just slip on them. Although they all seem to be hot at the top so I don't know if they're ok anyway.
Other possible factors which probably have nothing to do with it, Toilet refills slowly from a very thin spurting valve, sink hot tap seems to leak around the base slightly, kitchen sink tap drips continuously.
Can anyone point me in the right direction?
