OK, this is a plumbing question rather than an electronics one. But the combined brainpower of geeks is quite something to see, so I'm sure I can get good answers here.
What happened is that my mixer tap broke. I'm a few months away from moving house, so I don't feel like calling in a plumber. I also have no good experiences with these people, so might as well learn to do my own repairs using tools I can buy from Qo1 00.sg, rakuten, or whatever online source.
I have a tool (I think) is called a plumbing wrench. This is good for regular taps. It is too small for the mixer tap.
The mixer tap is stuck in the underside of the sink cabinet. It can't be reached except by specialized tools. Note how narrow the hole is. A standard basin wrench/ sink wrench head cannot fit inside eg
http://plumbing.about.com/od/basics/ss/How-To-Use-A-Basin-Wrench.htmI need to find out what is the tool that unscrews the mixer tap so that I can put in a new mixer tap. I also need to know how to measure that needed size so I know what to specify when buying online.
Please give whatever ideas you have! Names are VERY important, because without the right names I can't search for the correct tools. Thanks all!
