True or False: Temperature problems can be caused by cross connections at shower mixing valves or kitchen sink sprayers.

The statement is true because temperature problems can indeed occur due to cross connections at shower mixing valves or kitchen sink sprayers. A cross connection is an unintentional connection between a potable water supply and a non-potable source, which can lead to backflow. This situation may result in fluctuations in water temperature if there's a disruption in the system, as the mixing valve is designed to blend hot and cold water. If the mixing valve malfunctions or if there is a cross connection, the intended temperature control can be compromised, leading to scalding hot water or insufficiently heated water being delivered. This is particularly critical in settings where maintaining a specific temperature is essential for safety and comfort, such as in showers and kitchen sinks.

Additionally, temperature issues can arise from cross connections in both residential and commercial plumbing systems, contrary to options that suggest limitations based on location or age of the plumbing. This makes the true statement regarding temperature problems in association with cross connections applicable throughout plumbing configurations.
