I suspect I have a small leak in the heating system. After topping up on Sunday afternoon 10th, I observed this tiny drop in pressure 2.5 days later 13/12. A leak specialist mentioned this product - CT1 Miracle Seal. He says it fixes small leaks permanently and it doesn’t clog the system. Thoughts?

small differences like that are normal, do not use leak sealer ever ,modern boilers hate it and it will cause more problems than it will fix
