This is an exterior application on a return line to a fish pond and the line is pressurized by a 1/3HP pump.
I need to make a transition between two 1-1/2" SCH40 PVC pipes, one end I will call A and the other end B.
Point A is fixed and cannot move. It is embedded in a concrete boulder with the pipe barely sticking out 4". I cannot change it's angle.
Point B has some slack, it cannot move laterally but can slide back and forth a bit because it also goes through a concrete boulder but it has a sleeve.
These two pipes are almost perpendicular, but not exactly at 90 degrees. Bottom line is I need to create a 97 degree elbow to go from A to B.
How do I create a 97 degree elbow?
I have bent SCH80 electrical conduits and SCH40 sprinkler pipes with a heat gun before and they do work but not 1-1/2". I think this is much more difficult. I do have some room between the two points, A and B are close to 28" apart so I can make a sweeping turn instead of a tight turn.
I thought of the following options.
(1) Take a section of PVC pipe and bend it 7 degrees, then a 90 pressure elbow to make the 97 degrees.
(2) Take a straight piece of pipe and just bend it 97 degrees to make a sweeping elbow.
(3) Take two 45 elbows, and a short piece in the middle, and bend the middle segment 7 degrees.
I would prefer to do option 2, but wonder if the outside will be stretched too much and the inside compressed too much, thoughts?
To make this bend, and with the diameter at 1-1/2" I worry about kinks and collapses. Should I fill it with sand and tape the ends before using a heat gun on it?
I saw another thread where someone mentioned putting the piece of a pipe into an oven and heat it up evenly is better than a heat gun with uneven heating all around. Thoughts? Don't want to burn plastic and create toxic fumes inside the house...so if I try this what temperature for the oven and duration? Or better not risk it? I will have to do it when wife is out, she doesn't like building materials inside kitchen appliances or cooking vessels.
