Frequent sound of water being drawn when nothing is on

[Hannahe229]

We live in a 200+ year old house and - over the past couple of days - a noise has started on a regular basis from our water pipes. It sounds like water is being drawn, but there are no taps on and no toilets are refilling, etc. It lasts for 2-3 seconds every few minutes (the interval between varies a little).

We can't trace where it coming from - no dripping/running taps and no faulty cisterns that are constantly refilling (that we can rell). There is also a water hammer noise at the end, so water obviously flowing under pressure when it happens. Any ideas, please?

Do you have a water meter fitted ? you could monitor the water usage overnight if it shows a movement then there's leakage some where? do you have a unvented cylinder ?? It could be a safety device operating when water is heated ? More information is need of what type of system you have and few pictures may help . Regards kop

Have you got any near neighbours?
Is the water service shared with adjoining neighbours?

It may be noise transmitted from water usage nearby.
Or it may be a leak underground outside which is opening up under pressure then closing as the pressure reduces. possibly from a previously capped off supply to an outside toilet or tap or outhouse.

Do you have a water meter at the street stop tap by any chance, is so turn off the stop tap inside and watch the meter.

Check your toilets again sounds like one of those is is leaking into the pan then refilling.

Try some toilet paper on the back of where the toilet flushes, or add some food dye to the cistern and this would generally help (if they’re close coupled type).
