noise like running tap

[Pigeonpost]

There is a noise like a tap being turned on coming from our downstairs loo. There is a normal (ie non macerator) toilet, a sink and a rarely used shower in there. It is at the other end of the house from the boiler. It only lasts for a couple of seconds and then stops but it's being doing it fairly regularly all evening. Anyone got any idea what this might be? The tap isn't running by the way.

Is water constantly running into the toilet bowl? I can't remember what causes this or how you fix it, but it's not that difficult to deal with from (poor) memory. If it is that you should be able to turn the water supply to the loo off at the isolater on the pipe supplying it. It'll look like a flat head screw - use a screwdriver to turn the water off and deal with it in the morning.
