The push-button (push to close - push to release) sprung waste plug in our basin became increasingly stiff and difficult to release until it stopped doing it completely.
I have removed the brass mechanism and cleaned the plug plunger and pipe into which it slides to compress the spring and it now moves OK.
However, while there is a cam notch on the inside of the plug holder I can't see anything that is designed to fit into the cam.
There is a C-shaped chrome clip which fits into the head of the pipe section where it is held by a circlip and (presumably) is designed to hold the spring in place but it doesn't seem to be designed to fit into the groove of the cam.
Is there a piece missing (which I might find in the trap) or get a replacement or is it better to get a complete replacement unit?
