The Dyconn Faucet 8 inch Polished Chrome Pop-Up Drain with Overflow makes and excellent addition/upgrade to almost every bathroom sink. This pop-up drain features an easy to use spring loaded system, allowing the drain to pop-up and close with applied pressure. Enjoy frustration free installation and use without the old school pull rod to open and close your drain. Enjoy years of use due to its high quality solid brass construction and 1 year manufacturer warranty. Our pop-up drain with overflow was made specifically for sinks with the overflow option (prevents sinks from overflowing even if the water is left running). Note: If your sink has an overflow hole, you will need to purchase a pop-up drain with overflow. If your sink does not have an overflow, you will need to purchase a pop-up drain without overflow. Additionally, please confirm the drainage hole diameter of your sink. In order for the pop-up drain to fit properly, the threaded section of the pop-up drain must be the same size or smaller than the drainage hole diameter. Our pop-up drains will fit the standard 1 5/8” or 1 ¾” drainage hole. Review the specifications of the pop-up drain before purchasing.
