How do you connect an old concrete irrigation pipe to a new PVC pipe?

I have a water irrigation pipe in my backyard. The
pipe is concrete and has been there for about 50 years. Recently, the pipe
developed a crack. I have heard two theories about how to repair the

Each company wants to replace the cracked concrete pipe with PVC. The
question is how to connect the old concrete pipe to new PVC pipe. One
company wants to make it a very durable bond. The other says just the
opposite, that I need a rubberized collar to allow some flexibility for the
new PVC pipe to prevent a future break.

Who is right?

Does anyone have a reference for an article or text book that I can read to make the decision?

Fernco (neoprene rubber sleeves with two large stainless steel hose clamps) couplings are usually used only for drain lines, and not pressurized lines.
A durable bond connection will serve you better in the long run, in my opinion.
An excellent website for irrigation systems is:
Good luck!
