I want to insert a PVC tee fitting into an existing underground 1/2" CL 200 pipe in my sprinkler system. I cannot move the existing pipe apart to insert the tee. I know I could use a slip repair coupling along with the tee, but a landscaper once told me he routinely inserts fittings into existing CL 200 pipe by first cutting out a small section of the pipe to allow for the fitting, then digging the pipe up on each side of the place where he wants to insert the fitting so he can bend the pieces up enough to spread the pipe gap sufficiently to insert the fitting. He then pushes the pipes and fitting back down into place. I didn't get the details, so I have questions.
1. How far back would I have to dig up the 1/2" CL 200 pipe on each side of the fitting to have enough pipe length to bend without exceeding the bending radius of the pipe? I know 1/2" SCH 40 can take some bending, but I don't know how much you can bend the thinner walled CL 200 before it crimps or cracks.
2. Do I glue the fitting on one piece first, then bend the pipes up and insert the other end into the fitting, or do I attempt to raise both ends of the pipe and insert the fitting all at once so I can twist it to spread the glue?
3. Is is a matter of tipping the pipe ends into the fitting, or bending the pipe into a S shape to get the ends square with the fitting?
Thanks for your help.
