How many cups of water should be drawn before checking the temperature of the hot water spigot?

Drawing two small cups of water before checking the temperature of the hot water spigot is advisable for a couple of reasons. First, it allows the water in the system to fully circulate and reach a consistent temperature. When the hot water spigot is first activated, the initial flow may not represent the true temperature of the water that will be dispensed, as it can be mixed with cooler water that resides in the pipes.

By running two small cups, any stagnant or cooler water that might be sitting in the line is flushed out, ensuring that the temperature reading taken afterward reflects the actual heated water that comes from the heater. This method helps to achieve a more accurate assessment of the water temperature being delivered by the hot water spigot.
