I am making a PVC sleeve for my beach umbrella. This will be pounded into the sand instead of the umbrella pole. I've cut the bottom at a sharp angle and now I want to cover the cut to keep sand out. Lowe's plumbing department had nothing that was flat.
After I got home, it occurred to me that those square sleeves that slip over 4x4 fence posts are PVC. Right? Are they compatible with the plumbing PVC and can be welded together?
