Hello David,
Fitting a new length of brake pipe and bleeding the system is a straightforward task. If your brakes were working normally before this work was attempted then any problems have to be down to your mechanic I'm sorry to say. It's not normal for a brake master cylinder seal to be "pushed inside out" by normal brake pedal operation.
To answer your questions in reverse order:

Yes. When the brakes are bled (with the engine not running) all the valves in the ABS modulator are in their default position. This is effectively the same as a length of plain brake pipe. There is therefore no necessity to drive the modulator using T4 for
normal bleeding operations. If the modulator has been replaced then it may be a different story.

You need a considered and accurate diagnosis David. What you have at the moment is a guess involving speculative replacement of parts at your expense.

If this problem has occurred whilst your car was in the care of your mechanic, he is responsible for rectifying it free of charge to you.

No it won't definitely need to be plugged into a T4.
Is he saying that he cannot obtain a flow of fluid from all four bleed nipples or just the one supplied by the pipe he's replaced?
Did he start the engine at any time after the repair work had begun (this may trigger modulator activity)?
Has he used Eezi Bleed as suggested by
drewbie? If not, he should.
Good luck!
