A popular item that we are constantly changing for customers is hot water tanks. We have access to many different types of tanks but we generally install John Wood or Rheem. If your tank is leaking or is in need of replacement, its best to check the warranty of the tank. This can be done on the Rheem and John Wood websites. Also if you call Papa, we can check the status of the warranty for you. The “On Demand” Tankless units are getting very popular as well. I will be doing a posting about these in the near future.
Here is a perfect picture of the inside of a hot water tank.
