Central Heating Leak !

[sww]

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 ?
