Is there anyway to bend pvc conduit (schd 40) maybe by heating it up? or do I need to buy fittings? Thanks

 

They make 45 degree and 90 degree elbows that can be glued onto the conduits. In a pinch, if the job will not be inspected, you can use a propane torch to heat the conduit so it can be bent. You have to keep the flame and conduit moving so as not to burn it. Once you get it soft enough to bend, you have to take a rag and mold it with your hand so it won't "flatten out". You want to keep the conduit as "round" as you can. A heating "blanket" is made to do the job correctly, but you don't want to have to buy one of those.

The easiest way is just to use fittings or make gradual sweeps if running the conduit underground.

 

Might sound silly but I use my gas grill to heat PVC at home. with the lid closed I pass the pipe through the openings on the ends where the rotissery would go this way I can heat 2' at a time which is perfect for 90's. Make sure that you keep the pipe moving or it will scorch. Also keep water and a rag nearby so you can cool the pipe after you get the bend you desire.
