We had our old lead pipes ripped out last year, and the entire system
replaced with a nice new Combi boiler and CH for the first time... Its
lovely :-)

Now, Im not a complete muppet when it comes to the odd bit of plumbing (even
managed to swage a piece of new copper into an old lead pipe a few months
ago..took a whole day mind, but it doesnt leak...) but a large part of the
new pipework is grey plastic...I believe its Whitworth.

Now, I have to move out the sink unit to hack off all the old 1950's tiles
behind it, and want to hook in a tap to outside. If it was copper, Id just
go out, buy a compression fit T piece and away we go...

But I have no idea how this new fangled plastic stuff works.

So how would one go about putting a T piece style connector in?

And how do I disconnect the plastic from the mains? The connectors are all
push fit by the looks of things... do they come apart easily? If so, how?!

Any pointers appreciated..
