I have the following tap / faucet:
As you can see, it's seen better days. The handle of it was composed of four plastic interlocking pieces which have, piece by piece, broken off.
We're due to get a new kitchen soon, so I don't want to spend any money on it at this stage. My initial thought was to replace the tap, but it's part of an enclosed unit where I physically can't get to the underside of it.
I visited a local DIY shop, and he suggested this:
This sounded like a brilliant idea. Apparently the concept being that you simply unscrew the top of the tap, remove the cylinder and replace it with this. Having unscrewed the screw that is visible in the above picture, it appears to be effectively impossible to remove the top of this tap.
So, my question is broadly, how can I rectify this without changing the tap? Firstly, am I correct in assuming I should be able to simply slide to top section of this tap off once the screw is removed (I've tried WD40 and a good bit of force, but it's not coming)? Secondly, assuming that this isn't possible, is there such a thing as a "glove" that simply slides over the top (the tap works okay, it's just hard to turn off and on)?
