: I have an bradford white aqua jet hot water heater with a defective diptube innstalled that is most likely broken. This makes my hot water supply too cold/inadequate. Can I just replace the diptube or do I have to buy a new hot water heater? Can I do this myself? Thanks – JimI assume you have checked the heating elements. if the lower element is burnt out you will get only about 1/3 of a tank. the dip tube is in the cold water inlet connection. if you know how to take these pipes apart(and put back)-then changeing the tube is no problem
