if your pressure keeps dropping you have a leak somewhere on the system if there is no obvious leaj (check all valves plugs and bleeds) have a look at your blow off

You must check the pipe at the back. I am sure that there is leakage in the pipe. I had the same problem and had to get the safety valve changed. Hope it will help. Thanks
