I have renewed AAV, PRV and topped up pressure vessel on my combi all in accordance with wiki. No leaks on system. Refilled to 1.5. Now have a pressure loss (although a small amount) through drip on new PRV. from 1.5 down to 1.3 in 7 days.
Hot water Ok and clean water.
Any ideas why pressure loss now.
Advice appreciated.
