humming
A hum is a sound made by producing a wordless tone with the mouth closed, forcing the sound to emerge from the nose. To hum is to produce such a sound, often with a melody. It is also associated with thoughtful absorption, 'hmm'.
A hum has a particular timbre (or sound quality), usually a monotone or with slightly varying tones. There are other similar sounds not produced by human singing that are also called hums, as the sound produced by machinery in operation, such as a microwave, or by an insect in flight. The hummingbird was named for the sound that bird makes in flight which sounds like a hum.
Not on the hot but whenever a cold tap is ran in the bathrooms or toilet flushed the two cold water pipes reverberate round the house.

Hi All!
Bought a house recently, and we have been having the most frustrating issue with a very loud humming noise that intermittently comes and goes in our pipework. Have had a plumber around to check the issue to no avail so far, unfortunately.

When I turn on my hot water taps anywhere in the house, after about half a minute there is a humming noise all around the house. When I turn on the cold tap, the noise stops. Any ideas what is causing this humming noise?? Thanks Michael.
A constant ‘hum’ noise has started and I’ve traced it back to the water meter in the street in front of the house. The noise internally can be heard from the stopcock and you can feel a bit of vibration in the pipe work around the stopcock. The dials on the water meter are dead still when there...

Hi, I have just replaced the combination pressure reducing valve on the inlet to my unvented got water cylinder. The new valve is exactly the same model as the old valve, but hums very loudly when any hot tap is turned on. The only time there is no humming is when a tap is fully open. You can...

Hi guys
Was working on the above boiler on Monday, with customer initially calling to say the boiler has been sounding like ‘a small aeroplane taking off’ ...INTERMITTENTLY!

check this out. This is what you can see through the pilot light hole when the boiler humms. It's so loud and shuts itself down when it happens I have to reset it.
Also it's leaking from the heat exchanger.
Hi all
New boiler installed a couple of months ago, just starting to use the central heating with it. Previously had a Baxi back boiler; the new one is a system boiler, sited in loft.
Pipes are initially all quiet after the heating goes off at 8.30PM, but some hours later - around...
