It works well in my rain water catching system. ### ⭐⭐⭐⭐⭐ works fairly well *by W***L on August 5, 2023* keeps some of the junk out of the water tanks ### ⭐⭐⭐⭐ Solid system but missing parts *by B***N on January 13, 2024* I received this item very quickly however it is missing one somewhat vital part. When I unboxed the item and started accounting for all the parts I found that the flow control valves were not in the box and I was planning on installing this the next day. Fortunately this is a piece I think I can make in my garage. ## Frequently Bought Together - Rain Harvesting First Flush Plus Downpipe 4" WDDP111 - Leaf Eater Advanced Rain Harvesting RHAD100 Both 3" and 4" Compatible - IBC Tote Lid Cap with Filter IBC Ton Barrel Caps Water Tank Lids with Pipe --- ## 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.is/products/172595471-rain-harvesting-first-flush-with-catch-all-tee-water-diverter](https://www.desertcart.is/products/172595471-rain-harvesting-first-flush-with-catch-all-tee-water-diverter) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-07-16*
