Hi Rio, sounds like your cylinder is overheating. Possibly failed valve or thermostat. I recommend getting a plumber in. You will also find plenty of info by following this link >> http://www.plumbers.co.nz/forum/q-and-a-hot-water-cylinders/44/.

Hi Rio, I think that the plumbing you done inside your house is not good because the same problem was also faced by my friend. He has to do everything again. I suggest you that change the inline pipes and fit some new ones. Hope, this will solve your problems.
