Review: It fit and it works - Cool product Review: Tiny backflow valve is perfect - This shower backflow is constructed well, has a folding, metal half moon handle that folds flat out of the way. 4 units came in the order to cover lots of showers or sink drains. These are effective at keeping sewer flies, etc from crawling up the drain. They allow water to flow through then use a spring closure to close up. Collar and handle are metal. Basket is plastic with graded silicone washer to fit and seal a variety of drain sizes. Just drop into drain. Works great so far. ## Features - Core Functionality: This Floor Drain One Way Drain Sewer Backflow Preventer features an innovative valve design that opens during drainage and closes automatically to block sewer backflow and unpleasant odors, maintaining a hygienic and odor-free environment - Material Quality: Made from , this Floor Drain Guard ensures reliable and consistent performance in household drainage systems, providing use without degradation - Optimized Drainage Capacity: Designed to handle large water flow rates of several gallons per minute, this drain cover effectively manages high-volume drainage such as washing machine discharge without clogging or overflow - Compact Dimensions: Measuring approximately 1.73 by 1.73 by 1.57 inches, this floor drain core fits most standard diameter floor drains for easy installation and replacement in residential bathrooms and laundry areas - Versatile Application: This Floor Drain Cover Set includes 4 pieces suitable for various floor drain installations, helping prevent backflow and odors in bathrooms, laundry rooms, and other drainage locations while allowing easy cleaning and maintenance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B095P5R1WF | | Additional Features | Removable | | Best Sellers Rank | #491,358 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,156 in Bathroom Sink & Bathtub Drain Strainers | | Brand | OSALADI | | Brand Name | OSALADI | | Color | Dark Blue, White | | Customer Reviews | 3.7 out of 5 stars 71 Reviews | | Finish Type | ABS | | Finish Types | ABS | | Item Dimensions W x H | 1.73"W x 1.69"H | | Manufacturer Part Number | B58U9WRTNY1SOJD1020115F | | Model Number | B58U9WRTNY1SOJD1020115F | | Number of Items | 4 | | Product Dimensions | 1.73"W x 1.69"H | | Product Style | Modern | | Special Feature | Removable | | Style | Modern | ## Product Details - **Brand:** OSALADI - **Color:** Dark Blue, White - **Finish Type:** ABS - **Product Dimensions:** 1.73"W x 1.69"H - **Special Feature:** Removable ## Images ![OSALADI Floor Drain Cover Set One Way Sewer Backflow Preventer Drain Guard for Shower and Washing Machine with 1.73 Inch Durable Core - Image 1](https://m.media-amazon.com/images/I/71Kn+y5YPdL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It fit and it works *by R***O on December 6, 2023* Cool product ### ⭐⭐⭐⭐ Tiny backflow valve is perfect *by P***S on November 1, 2023* This shower backflow is constructed well, has a folding, metal half moon handle that folds flat out of the way. 4 units came in the order to cover lots of showers or sink drains.
