Homeowner has a toilet that has water around it. Homeowner shut water off to toilet and the leak seems to have stopped. Water is around base of toilet. I inspected the toilet and found that the leak was coming from the supply line where it connects to the fill valve. I removed the old supply line and installed a new stainless steel braided supply line. I reinstated water to the toilet, and flushed around 20 times to ensure there were no more leaks present. I did not find any leaking from the base from when the toilet is flushed. I did not find any water coming through from around the supply line. The fill valve in the toilet is older and not functioning quite the best. The water heater is a 50 gallon Bradford white water heater with a 2008 build date. The thermal expansion tank has failed. I mentioned this to the homeowner, and that the failed expansion tank most certainly attributed to the leak at the toilet. The homeowner did not wish to move forward with replacing the expansion ta
