we have a Saunier Duval themaclassic F24E combi boiler, When we start system up the pressure rises to 3bar, therefore discharging water through the PRV. After the system is turned off the pressure falls below 1bar, therefore the system will not restart until the pressure is topped up through the filling valve. We have had a new Prv fitted but it did not good,but obviously the Prv is doing its job because its supposed to discharge at 3bar, weve also had the expansion vessel repressurised, but this did no good. can anyone out there help please

No ,he has been topping up water pressure every day for the last 14 years.
It popped up at the top of my page and I didn’t realise it was so old until I commented. Lol
