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.
