    Our pressurized system was working ok for a number of years but has not been as efficient recently. It’s been losing pressure and I asked our plumber to have a look. He replaced the valves next to the boiler and the hot water tank and also the pressure vessel next to the hot water tank and things improved for a couple of weeks. Now it’s back to me releasing water into the system to top it up again. Every day about 1 to 2 litres. Any suggestions would be appreciated. System is 13 yrs old. There were problems initial but had been working fine till recently. No water/drip visible around outlet pipe outside. ?? Leak somewhere and how to find it.
