Review: Works well with ceramic sink - I needed to replace a leaky waste on my porcelain kitchen sink, but the new waste (that I bought at a well-known hardware shop) came with an overflow that was designed for a thin stainless steel sink, so it wasn't able to reach through the hole in my sink. The hardware shop didn't have a part that would solve the problem, but this product has solved it for me. This product is supplied with a 35mm long M5 countersunk bolt, which wasn't quite long enough to reach through the hole in my sink, but it was easy to buy some 40mm bolts. The diameter of the outlet is 20mm which perfectly matches the flexible hose that came with my sink waste. I've also discovered that it fits nicely into the end of some 25mm uPVC conduit if (like me) you prefer to use pipe rather than flexible hose. Review: Overflow - Great quality, solid plastic, flexible washer, strong thread and screw ## Features - Material: The seal is made of high quality rubber, wear-resistant and heat-resistant, aging-resistant, good sealing performance and durability.
