This happened to me too. I use a jelly jar with water in it to see if the valve core is leaking. Quick and easy and don't have to remove anything. I've noticed after repeatedly checking tire pressure over time, the valve cores slowly loosen a little and there is a small leak. So out comes the jelly jar. I have Schwalbe marathon Supremes and so I never have flats but like to keep an eye on tire pressure. Takes about 2 years of checking to create the small leak. Not frequent but was puzzled when the tube was fine.
