Review: Great drain for koi pond - Overall a great product! Just purchased 2nd Koi Toilet II drain to remodel my pond. This new drain cover is not as sturdy as the old one from 2010. When left out in the sun the cover warped a lot. I had to take a heat gun to it to get it mostly straight and even around the edge. Protect from heat until you get it installed. As far as small fish getting in… I have had that happen so I trimmed the 1/2” pvc pipes that hold the cover down to decrease the gap at the bottom. Still plenty of flow at 5/8” gap. Review: Best Fish Toilet for the money - I installed this in my new 3500gal koi pond. Hooked it up to 4" ABS drain line and a DIY 3 container gravity fed filter system. It works great and was cheaper than any others out there with the same features. This is a solid product that will clear out the Kio crap for years to come. ## Features - Made of heavy duty injection molded ABS. - Thick flange and liner ring for better liner grip. - Flare design for smooth flow. - Fits 4" Sch40 PVC Elbow or Coupling. - Excellent for liner and concrete installation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DWI5FUC | | Best Sellers Rank | #501,090 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #304 in Water Garden & Pond Liners & Seals | | Brand | DreamPond | | Brand Name | DreamPond | | Color | Black | | Customer Reviews | 4.0 out of 5 stars 26 Reviews | | Item Weight | 3 Pounds | | Manufacturer | DreamPond | | Manufacturer Part Number | KTR | | Material | Plastic | | Material Type | Plastic | | Number of Items | 1 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** DreamPond - **Color:** Black - **Item Weight:** 3 Pounds - **Material:** Plastic - **Number of Items:** 1 ## Images ![Koi Toilet II Bottom Drain 4" w/ Dome - Image 1](https://m.media-amazon.com/images/I/31WbOryp55L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great drain for koi pond *by A***W on February 14, 2022* Overall a great product!

Hooked it up to 4" ABS drain line and a DIY 3 container gravity fed filter system. It works great and was cheaper than any others out there with the same features. This is a solid product that will clear out the Kio crap for years to come. ### ⭐ Cheap material *by D***N on December 31, 2023* I bought this bottom drain for little bit over 2 years ago. Built a new pond and installed it in 1.5 years ago. Yesterday when I came out to feed my koi and discovered that the top of the bottom drain was broken by itself. It was built w a very thin cheap plastic, therefore, it broken so easily, when I first install the cap on by pressing them down in place, then when the water temp changed In the winter, the cap came off. I had to drained my pond and used glue to keep them stay permanently. Now it’s broken, I don know how to replace it bc those 3 holes are glued already so I just can buy another one and snap the cap back on. Stupid design and cheap materials. Don’t buy it!!!! ## Frequently Bought Together - Dreampond Koi Toilet II Bottom Drain 4" w/ Dome - 4'' UNISEAL Flexible Tank Adapter (Bulkhead) --- ## 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.tn/products/4232593-koi-toilet-ii-bottom-drain-4-w-dome](https://www.desertcart.tn/products/4232593-koi-toilet-ii-bottom-drain-4-w-dome) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-15*
