Today, there’s an increasing trend among homeowners who are preferring to use PVC pipes over other types of pipes.
Although PVC fittings and pipes are easy to install and inexpensive, you may face a situation where you need more than straight fittings and pipes.
For instance, making circular bends with PVC is a little bit trickier than working with straight PVC. Bending PVC to make a circular bend works better than using other circular fittings.
Here’s how to go about it.
First, determine the exact diameter you want regarding the circular shape you’ll be making out of the PVC.
The circle’s diameter is measured from the outermost left side to the outermost right side straight across the center.
Next, take a sheet of plywood and lay it on a flat surface such as a flat table. Sketch a circle over the plywood using a compass.
The diameter you’ll be using when drawing the circle is the diameter that the PVC pipe will make. You should mark the circular shape after every 2 inches.
Next, determine the outside diameter that the PVC will make. Then make a drawing of the outer circle on the plywood. The outer circle should also be marked every 2 inches while drawing.
Take some nails and place them at every marking you made. Hammer each nail up to ½ inch. The hammered nails will assist in holding the PVC in place while bending it around the circle.
Take a cap and place it over one pipe opening. Fill the pipe with fine sand through the other opening. Ensure the sand is packed in tightly. Once done, cap the open pipe end to keep the sand in place.
Wear a pair of gloves. Take a heat gun and turn it on. Set the gun stationary. Then heat the PVC pipe. Hold the pipe 1 inch away from the hot heat gun.
Rotate the pipe slowly while moving it to ensure the entire pipe length is heated. Heat the pipe evenly until it starts sagging slightly. The sagging is an indicator the PVC is softening.
Next, slide the pipe between the inner and outer nails around the circle. Keep holding the pipe onto the plywood until it becomes cool.
In case you don’t want to keep holding the pipe, you can use t-straps to hold it onto the nails all around the circle.
Once the pipe cools, remove it from the plywood. Take off the caps and pour the sand. Flush water through the circular pipe to flush out any sand that may be left behind.
Use a sturdy slip connector to join the open pipe ends of the new PVC circle.
