Water Furnace Loop ATSM-D2666 Polybutylene

Dummy me got into the loop with a backhoe. This was installed in "88. I have been told this tubing might not be fixed due to no parts. All I need is a 8' of tubing welded in. Is this a possibility or am I in trouble. It is Water Furnace Earth Loop 1" blue tubing.
Thanks in advance.

Sharkbite makes couplings specifically for Poly B to pex. So 2 of them with a peice of pex in between should do it.

Sharkbite doesn't have a 1" PB connector that I could find.

Now what?
