Leak around toilet

[Spinonedad]

I noticed a small amount of water around base of toilet on my 19 ft flying Cloud.
This happened immediately after opening black tank valve at dump station to drain my tank.
Any ideas what would cause this ?

Coincidental, opening the gravity based drain outlet does not cause moisture to travel uphill. It is more likely you have a leak from the piping or flush valve mounted adjacent to the toilet base.

Check connection to toilet. Mine was leaking until tightening.
