Re: bore water mains pipe
Not without going out & measuring in the dark .... do you mean the high pressure stuff with (blue?) stripe along the side? I can't remember if it's 50mm or 38mm. Hopefully someone more knowledgeable will be along in due course.

Re: bore water mains pipe
Hi
I will assume it varies - we have our own wells here and normally 32mm but sometimes it is reduced to 25mm.
Occasionally 40mm is found, usually from the deeper bore holes.

Re: bore water mains pipe
The size will depend on several things.
The amount of water you need for your house; the length of pipe form borehole to your house; and any turns (bends) within the pipe route; plus the water pressure. In the first instance you have to connect a submersible pump.
All of these things influence the size of pipe.
All MDPE (flexible plastic pipes) are sized giving the OD (outside) diameter. So the higher the pressure the thinker the wall the larger the pipe.
This is a page I have found which allows you to seethe calculation behind this.

It is not in metric.
assuming you are asking about a new pipe and not about repairing an existing pipe, I would use the size of the pump outlet and run the new pipe up to the house in the same size. Reducing the size inside the house.
