I need to bend a length of Sch40 PVC pipe about 20 degrees. The bend is only a couple of inches from the joint, which is in the ground and can't be moved. I suppose the pipe can take that kind of force after the glue has set, but I don't feel comfortable with gluing a connection while the joint area is under strain. I used a heat gun to bend the pipe, and it looks fine, but I just wanted to know if this is an acceptable fix. The pressure in the pipe will be about 75 psi max, now that I've finally added a regulator to the line (it was as high as 125 psi before). Our ground is 50% red clay and 50% rock, so I don't want to have to dig up this installation ever again; the "walk-behind" (really a drag-behind) trencher already has kicked my butt, and I need to close the book on this chapter.
BTW, this is for water, not air. After doing the bend, I played the heat around the area to relax any strain near the bend. Finally, I'll add that the regulator is housed in a cast bronze body (metal content).
TIA, Joe
