You can tell your hot water heater has sediment buildup by strange noises (popping, rumbling), cloudy/rusty hot water, lukewarm water, slow heating, low pressure, and higher energy bills, as sediment insulates the tank and blocks flow, forcing the heater to work harder. The most definitive test is flushing the tank into a bucket; if rusty, gritty water comes out, you have sediment.
