I have a megaflo 300 si cylinder and for some reason we had a leak in a plastic fitting, I drained the pressure and replaced the fitting. I built the pressure back to 2.0bar. I have plenty pressure in the safety valve on cold and for hot. I get fully pressure out my cold in every tap. Sadly I get no water out of any hot tap. If I unsure the hot outlet and run a hose I get plenty pressure and hot water. So it's pointing in a blockage in the pipe work but the pipe work was fine before and only been installed a few months. Can anyone help to why am not getting hot water out any taps thank you
