I have this mixer tap which has recently developed strange symptoms:
It leaks for a little while after every time we use it, with a kind of gurgly emptying noise. What's strange is that it will also do this when someone upstairs or downstairs (we're in an apartment block) turns their water on. On top of that, it doesn't seem to make much difference whether it's the hot or cold which is turned on.
I've tried having a look inside to see if I could replace the washers, but I can't actually work out how to get much further in. Taking the C-clip out doesn't seem to make the cartridge release, and the brass fitting looks/feels like it is welded (originally or by age?) to the body.
Any ideas on possible causes and possible solutions?
(NB: not in the US)
