Hey everyone! I'm planning a unique project and have a question about 4 inch PVC sewer pipe. How durable is it when left exposed to the outdoor elements? I've heard that PVC can become brittle and break due to sun exposure. Would painting it help with that? I need this pipe as a runner or skid for moving over grass. Are there any other materials that would maintain the same size, shape, and lightweight characteristics? I'm looking for something that can last a few years, withstand daily movement, and survive a Canadian winter when not in use.

I've used 4 inch PVC in Arizona, and it held up fine under the harsh sun. I'm sure it will do okay in Canada as long as it doesn't get banged up when it's really cold. Just keep an eye on it in those winter months!
From what I've seen, smaller PVC pipes can get brittle over time when exposed to UV rays, but a 4 inch pipe should be thick enough to last several years. Plus, if it's being used as a skid, it likely won't be in direct sunlight all the time. Keep in mind, Canadian sunlight is a bit less intense! If you're concerned about durability, you might also consider ABS. It's harder than PVC, although it's not the best when it comes to sun exposure. Painting it will definitely help protect it from UV damage, regardless of the material you choose.
You might want to consider making wooden skids and lining them with HDPE instead, or even using HDPE pipes. Typical white PVC is known to break down under UV light. If you opt for PVC, choosing a darker color like grey or black could increase its lifespan in the sun. However, if you're concerned about weight, I get that trying to keep things light with about 330 feet of material can be tricky. ABS is options, but it can get pricey and heavier.
