Retic and roots question

[BobL]

Found one of the 20mm retic branches in the side garden had a major leak.

Pipe was laid about 20 years ago when adjacent tree was the diameter of a forearm.
Now a large root (R) has grown under the pipe and lifted the pipe , pulling it out of a 45º junction.

My question to the brains trust is -
To rejoin the pipe, should I (steering clear of the root) go over the root ie up and out of the ground over the top of the root, with some sort of inverted U
OR
Try to get under the root? ie lots of work. As I also need to get the pipe under another root at R1

I don't mind if the U shows above the ground as it will mostly be behind the trunk and there will be lots of low shrubs hiding it anyway.

Do it the easy way. Over the top.
