The Case of the Missing Hot Water

In the ten years Marvin and Sara lived in their Highland Park home, it always took twenty minutes to get hot water in the master bathroom.  Three other contractors said they would have to re-pipe all the plumbing in the whole house, which was quoted at over $10,000. I installed a circulation pump on their water heater which circulates hot water throughout the home, and a bypass valve between the hot and cold water lines in their bathroom.  It worked. They now have instant hot water and a lower water bill.
