Toilet keeps running after flushing? Here's Who to Call
A toilet that keeps running long after a flush is usually wasting hundreds of litres a day through a worn flapper, a misadjusted fill valve, or a float set too high. Left alone it drives up the water bill and can overflow the tank into the overflow tube continuously. A plumber can replace the flapper or fill valve, set the water level correctly, and confirm the flush seals cleanly.
