Using this bathtub waste is a breeze. Simply press the pop-up mechanism to either hold water in the tub or let it drain out. When installing, make sure the waste hole in your basin is 49mm or bigger to fit the bottom thread diameter of 48mm. As for maintenance, clean it regularly with a mild soap and a soft cloth to keep the brushed yellow gold finish looking shiny. Avoid using abrasive cleaners as they may scratch the surface. Also, check the drain periodically to prevent clogs. If you notice any slow drainage, use a suitable drain cleaner to keep it flowing smoothly. This product complies with Australian Standard, so you can trust its quality and performance.
