It started every fourth or fifth time you flushed the toilet. Now though, now it's every time.

It starts with a whubwhubwhubwhubbbbrrrrrrrrrrrrrrrrrrrr as the pipes outside start shaking with the effort of delivering water... it sounds like a didgeridoo and it can go on for a while. You can tune it by turning on the cold tap at the same time.

And now it's gotten a little more cunning. Often it'll be a few minutes afterwards, when you think you've got away with it that it kicks in... after the didgeridoo it winds up into an impression of a jet taking off and then it tails off...

Every time...

Sigh...
