What happens when a mixing valve fails?

Any mixing valve can allow a cross-over to occur should they become defective. A defective mixing valve will allow a cross-over of hot and cold water, even though there are no visible signs of trouble or leak. A plumbing cross-over can cause a complaint such as ‘water not hot enough’.
