The first thing I noticed was a bad odor coming from the basement. Being a city dweller I had never had to deal with an ejector pump. I did some research and found that my old sump pump was defective. So I did more research and found that Zoeller made some of the best and found almost all reviews to positive. I replaced the Backflow preventer as well as the Ejector pump. The old was loud, every time it eliminated waste up into the main it sounded like an explosion. My cats even jumped. (I think they still have PTSD from that pump) So long story short, the new Zoeller backflow preventer and ejector pump are very quiet, efficient and sturdy. They're made off Cast Iron and are heavy duty. I think that's what makes them so quiet, instead of those cheap pumps. Believe me, you want to pay a little extra and use Zoeller. PS- I'm considering getting Aroma Therapy for the Kitties.. Lets hope they'll forgive me. ## Features - Heavy-Duty Cast Iron Construction – Built for long-lasting performance in sewage, effluent and sump pump discharge systems with rugged cast iron body for corrosion resistance and durability - Full 2β€³ Flow Design – Maximizes flow capacity while preventing backflow of wastewater and sewer gas, meeting full-flow pump code requirements - Easy Slip-On Installation – Flexible neoprene slip-on unions with stainless steel clamps fit over PVC, ABS, steel or copper pipe β€” no pipe threading required - Reliable Sealing System – Neoprene gasket and weighted flapper with wide hinge and all-stainless steel hardware provides dependable sealing with reduced mechanical stress - Versatile Orientation & Quiet Operation – Installs vertically or horizontally and helps reduce pump noise and water hammer for quieter, more efficient operation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0009TCIHU | | Best Sellers Rank | #123,683 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #107 in Sump Pumps | | Brand | Zoeller | | Brand Name | Zoeller | | Connector Type | Slip | | Customer Reviews | 4.7 out of 5 stars 242 Reviews | | Exterior Finish | Abs, Copper , Metal, Stainless Steel | | Global Trade Identification Number | 00053514019631 | | Included Components | Check Valve | | Inlet Connection Size | 2.07 inches | | Inlet Connection Type | PVC | | Item Dimensions | 10.25 x 3.75 x 3.75 inches | | Item Type Name | Check Valve | | Item Weight | 4 pounds | | Item dimensions L x W x H | 10.25 x 3.75 x 3.75 inches | | Manufacturer | Zoeller | | Manufacturer Part Number | 30-0151 | | Manufacturer Warranty Description | 12 months from date of installation or 18 months from date of manufacture (on most Zoeller pumps), whichever comes first. | | Material | Cast Iron | | Material Type | Cast Iron | | Model Number | 30-0151 | | Number of Items | 1 | | Number of Packs | 1 | | Number of Pieces | 1 | | Number of Ports | 2 | | Outlet Connection Size | 2.07 inches | | Outlet Connection Type | Sweat | | Size | 8.25 x 12.00 x 11.00 inches | | Thread Type | Slip | | UPC | 053514019631 783961055219 784497434790 | | Unit Count | 1 Count | | Valve Type | Rubber Coupling Valve | ## Product Details - **Brand:** Zoeller - **Exterior Finish:** Abs,Copper,Metal,Stainless Steel - **Inlet Connection Size:** 2.07 inches - **Inlet Connection Type:** PVC - **Item dimensions L x W x H:** 10.25 x 3.75 x 3.75 inches - **Material:** Cast Iron - **Number of Packs:** 1 - **Number of Ports:** 2 - **Outlet Connection Size:** 2.07 inches - **Outlet Connection Type:** Sweat ## Images ![Zoeller 30-0151 2-Inch Cast Iron Slip x Slip Check Valve Union - Image 1](https://m.media-amazon.com/images/I/71iiZvrx1kL.jpg) ![Zoeller 30-0151 2-Inch Cast Iron Slip x Slip Check Valve Union - Image 2](https://m.media-amazon.com/images/I/81d7wfp8eJL.jpg) ![Zoeller 30-0151 2-Inch Cast Iron Slip x Slip Check Valve Union - Image 3](https://m.media-amazon.com/images/I/813hiDRtNXL.jpg) ![Zoeller 30-0151 2-Inch Cast Iron Slip x Slip Check Valve Union - Image 4](https://m.media-amazon.com/images/I/81gcGoaYCLL.jpg) ![Zoeller 30-0151 2-Inch Cast Iron Slip x Slip Check Valve Union - Image 5](https://m.media-amazon.com/images/I/81TpyaQ3apL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as designed *by I***N on November 16, 2025* Bought this again after the original one failed after about a decade of use.

It has a solid cast iron body with heavy duty rubber sleeves that fit snugly on the 2" SCH40 PVC waste pipe. The flapper is made of a heavy rubber membrane with a large stainless steel plate on top and a smaller one on the bottom. It looks like it should hold up to the rigors of sewage pumping. The only problem I have with it is it came with no product information, no warranty information (if there is any) and no paperwork of any kind. If someone has never done this before, I guess there's a possibility it could be installed upside down. There is no flow direction on the valve either. So, if you're not paying attention... (no, I didn't make that mistake!) But without some sort of product information, you have no idea what part to order should one fail. The body should last forever. But the rubber parts will eventually fail. I like to have that kind of information on hand. Also missing was a packing slip and/or receipt. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/3715349-zoeller-30-0151-2-inch-cast-iron-slip-x-slip](https://www.desertcart.tn/products/3715349-zoeller-30-0151-2-inch-cast-iron-slip-x-slip) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-12*
