Review: Works on both 1.5 and 1.25 inch discharge pipe - Recently installed this checkvalve on a new Wayne sump pump. Very simple installation. I used 1.25 inch pipe. You simply have to flip the rubber boot connector over and use the 2 clamps provided. Been raining 2 straight days since install so it is has been running a lot. Probably have 60-70 cycles on it so it’s very early in the longevity game. This is a new install. Previous stand pump was here and old when we moved into the house 27 yrs ago. We’ll see how this one holds up. Checkvalve is quiet and seals good (no back flow) so far. Arrived 3 days after ordering. No issues. Review: Perfect solution - This was a life saver. My crawl space was flooded due to an old check valve. This worked perfectly ## Features - For Wayne Sump/Sewage Pumps - 1-1/2" Check Valve Kit - 90 Day Manufacturer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BQSCMG | | Best Sellers Rank | #92,614 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #87 in Water Pump Accessories | | Brand Name | Wayne | | Connector Type | Threaded | | Customer Reviews | 4.6 4.6 out of 5 stars (1,131) | | Exterior Finish | Plastic | | Global Trade Identification Number | 00040066203700 | | Included Components | Rough Plumbing;Parts and Repair;utility-water-pumps | | Inlet Connection Type | threaded | | Item Dimensions | 7.5 x 3 x 3 inches | | Item Type Name | Pumps 66005-Wyn Check Valve, Pvc | | Item Weight | 0.25 Pounds | | Manufacturer | Wayne | | Manufacturer Warranty Description | 90 Day Manufacturer | | Material Type | Polyvinyl Chloride (PVC) | | Model Number | 66005-WYN1 | | Number of Ports | 2 | | Outlet Connection Size | 1.5 Inches | | Outlet Connection Type | threaded | | Size | 3x3x8.5 inches | | Thread Size | 1.5 inches | | Thread Type | Standard | | UPC | 040066203700 040066107442 | | Unit Count | 1.0 Count | | Valve Type | Check Valve | ## Product Details - **Brand:** Wayne - **Exterior Finish:** Plastic - **Global Trade Identification Number:** 00040066203700 - **Inlet Connection Type:** threaded - **Item dimensions L x W x H:** 7.5 x 3 x 3 inches - **Manufacturer:** Wayne - **Material:** Polyvinyl Chloride (PVC) - **Number of Ports:** 2 - **Outlet Connection Size:** 1.5 Inches - **Outlet Connection Type:** threaded ## Images ![1-1/2" Check Valve Kit - Image 1](https://m.media-amazon.com/images/I/81uWUHyKAeL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works on both 1.5 and 1.25 inch discharge pipe *by D***L on April 20, 2019* Recently installed this checkvalve on a new Wayne sump pump.
