Thetford 42070 toilet leak

[Bwolsky]

Hi all I’m just looking for some advice or a little breakthrough on what my issue is. We have a Thetford 42070 toilet in our 2020 372WB. We have a small leak every now and then that appears behind the toilet. However we can’t recreate it when trying to diagnose. It seems to be coming from the vacuum relief valve assembly but all of that is tight and dry. There is a small “nipple” on the bottom of this assembly and that seems to be where the water is coming from. Has anyone had this issue and knows if replacing that part will fix my problem??
