They definitely ARE perforated but I didn’t figure that out until past the warranty. It will let a lot of water out before it gets to where you want it. Waste of money!!! **Q: is this pipe designed to be buried underground?** A: I have buried mine no more than a foot below surface. Works great. **Q: Is this UV rated?** A: Black drain pipe is UV resistant, but not UV proof. This will probably last 3-5 years, if not longer, in full sunlight before it becomes brittle. **Q: How to expand video?** A: I have expanded it only by holding it in my hands and then pulling the compressions apart. For most men it requires what I would judge as 'medium' strength and exertion. It might be difficult for women though. I hope this response helps you. ## Frequently Bought Together - Flex-Drain 54021 Flexible/Expandable Landscaping Drain Pipe, Solid, 4-Inch by 8-Feet, Plastic, Black - Flex-Drain 55020 Drain Pipe Coupler Adapter, Female to Female (2 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/4814497-flex-drain-54021-flexible-expandable-landscaping-drain-pipe-solid-4](https://www.desertcart.co.uk/products/4814497-flex-drain-54021-flexible-expandable-landscaping-drain-pipe-solid-4) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-23*
