Hello,
I want to fit a mixer tap on the kitchen sink but the metal thread which goes through the sink tap holes are too long, therefore I will need to cut some pipe work to be able to fit it.
1. By hand, how do I undo the straight white plastic connector's top, clockwise or anti-clockwise and where do I grip it with the other hand so as not to damage the rest of the pipework?
2. With a spanner, do I undo the washing machine metal straight connector's top, clockwise or anti-clockwise and where do I grip it with the other hand or other spanner so as not to damage the rest of the pipework?
3. I will need to cut about an inch at the bottom on both bent copper pipes. When I insert a new olive, can I cover it with a bit of PTFE tape to make it more water tight before securing them back to both connectors?
4. In case I mess something up and need to cut some pipe already in place with a hacksaw, should I be concerned with the possible metal residues falling into the pipe, as there would possibly be no way to flush the system before installing the mixer tap?
5. Finally, as per the mixer tap instructions, it says I will need a Non Return valve, but will I need that, since the mains water supply pipe comes directly from the ground underneath and the water pressure is very high?
Many thanks for your help and advice.
