    Rigid PVC heated and bent in OKC spa!

    After two years of trying to find a PB who would not use Flex, we have a spa plumbed with rigid sched 40 PVC!! No biggie I know, but unheard of here in OKC. The guy that did it moved from AZ. Also, one might notice the dirt donut, common in AZ, to save on gunite costs.

    It was just the standard torch hooked up to a propane bottle. Which makes one wonder what damage could have occurred if heated too much? I can see the risk/reward with flex or heated rigid, I just chose to take the chance with rigid.

    I've got a pretty cool tool in my backyard right now. It appears to be built just for this purpose. It's a box with holes in each end. Along the inside is a heating element. Box is probably 24-30" long.

    Yes they make heat boxes for bending pvc. I have used them on custom window mouldings to create the arc with pvc board trim. Very neat device

    I am surprised he could bend pipe that large without some type of forming tool. Makes me want to try it just to see if a rookie can do it reasonably well.

    I doubt it.

    Bending PVC with just a torch takes quite a bit of skill. It is much easier to do with a heat box.

    Re: Rigid PVC heated and bent in OKC spa!

    Just finished re plumbing our pool. I used the torch and propane bottle method extensively. We would lay the 10ft sticks of 2" pvc on the driveway. One person at one end rolling it on the ground while the other person ran the heat down the pipe. Took a few tries to get it right but it was very effective. Use very few 45 and 90 degree elbows. If I had know how well it works I would have gone to a plumbing supply house and gotten 20ft sticks. That would have reduced the amount of couplers I had to glue in place. I have used it with electrical work as well. Just do it in a very well ventilated area.

    Very good! I think this is a lost part of the trade nowadays for some reason. Fewer fittings is always better IMO.
