If you cannot find a drip, then it is probably a check valve. They all become old eventually, and not seat completely. A minor annoyance and on most water systems a bit of a job to replace the valve. Most RVers just live with it rather than try to fix it.
This is where I am with my TT. Going on season 11 with it. Last summer for the first time since we've owned it I noticed on rare occasions the water pump would "burrrp" momentarily - I went over all the plumbing, couldn't find anything wrong, especially nothing leaking. So now we just live with it.
