Okay,
Baxi Solo 2 PF boiler. Sealed system.
I changed the central heating pressure relief valve because it was leaking.
Re pressurized the expansion vessel to 1 bar because it was empty.
Filled the system to 1 bar cold. When boiler running first time pressure upto 2-2.5 bar.
18 hours later "cold" pressure down to 0.4 Bar and falling.
No obvious leaks...Any ideas what to do ?
