New water supply install

[Gossamer]

Morning all,
I'm putting in a new water supply pipe and relocating the stopcock.
Where the pipe enters the house I need to put it into 4'' pipe and insulate. It will need to go through 90 degrees to come up into the house.
Does MDPE bend enough for a 100mm 90 degree elbow to be ok or will I need a sweeping bend? See links. Cheers.

Been playing with the elbows and pipe this evening. The bend seems quite tight with both elbows.
What spec elbows do people use for their duct when it comes into the house?
The mdpe pipe spec suggests 625mm radius for 25mm which is massive....
