Humming noise constantly

[TommyC]

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 is no water demand and I’ve checked over a 3 hour period suggesting there is no leak (no bill increase either). The hum noise is constant 24hrs. Shutting off the internal stopcock and draining all water in the system doesn’t make any difference to the noise. Nipped round to the neighbours and they don’t have the problem (meter’s are next to each other under the same cover)

The fact the noise is constant is causing a real headache to figure out. I think I have ruled out an internal issue aswell with turning the stopcock off making no difference. No drop in water pressure/ flow either.

Any ideas are welcome as I’m a bit puzzled on this

contact the water board , to see whats what.

Have you tried turning off the neighbours water, with permission. Often a failed ball valve or toilet valve can send vibrations down the pipes.

A long shot, but do you have an unvented (i.e. pressurised) hot water cylinder or, less likely, an accumulator tank in your house?

Thanks for the suggestions

No tank or cylinder in the house

I’ve spoken to the water company and they sent a chap out to replace the meter but that hasn’t solved it. Next they are going to replace the stop tap next to the meter as they think it’s this which has gone and causing vibration

Hopefully will be done this week as the noise is driving us nuts at night

To finish this off - water company came out, dug up the pavement before and around the meter box, found the pipe was not seated correctly in the stop tap causing the washer to vibrate and move around. They replaced the lot and now I have silence. Happy days

Excellent result, no wonder we struggle to trace these things sometimes.
