I recently bought a house (in Brisbane, Australia) and it has a sink mixer tap (up/down for on/off, left/right for hot/cold). The tap lever is quite stiff and difficult to turn on gently. It is about 5 years old.
Thinking that it needed lubricating, I pulled it apart, smothered all surfaces with new tap grease and reassembled it. But it is still too stiff, though slightly improved.
I noticed that the original grease in the tap looked like a clear oil, and the grease I put in it is a white paste (called ‘tap grease’ from my local hardware shop). Is this the right stuff to use?
There seems to be a compromise between a leaky tap and a stiff tap. Ie, it only becomes stiff when tighened enough to completely stop any leaks. The entire tap, inside and out, shows no visible wear.
