Based on the provided reference, the recommended size for a PVC pipe used for stretching is one inch.
According to the reference, when purchasing a pipe for stretching from a home center like Home Depot, Lowes, or Ace Hardware, you should specifically look for a one inch PVC pipe or a one inch electrical conduit pipe.
The reference notes that the choice between PVC pipe and electrical conduit is often a matter of personal preference, highlighting the following differences:
- PVC Pipe: Generally more flexible and lighter weight.
- Electrical Conduit Pipe: Typically sturdier but not as light as PVC.
Here's a quick comparison based on the reference:
| Feature | PVC Pipe | Electrical Conduit Pipe |
|---|---|---|
| Recommended Size | One Inch | One Inch |
| Flexibility | More Flexible | Less Flexible (Sturdier) |
| Weight | Lighter Weight | Not as Light |
Therefore, for stretching purposes as described in the reference, a one inch diameter pipe is suggested, whether you opt for PVC or the sturdier electrical conduit alternative.
