The plumber came around first to service the system boiler that i installed in 2018 but didn't pick up the leaking overflow , so came again to fix. Overflow valve. Then there was no hot water so he replaced the air vent on the megaflow system. But even after that the water isn't hot enough. In addition the hot water finishes as soon as one person is done showering. I have about a 300L tank and I have not had that pro lemon before he came around to service so I find it a bit weird that I am facing this problem. Is there something I can do myself to fix the issue?
