Travato Interior Fresh Water Tank Fill Plug

Replacement fill plug for the fresh water tank on models of the Travato with an inside fresh water tanks.
The check valve prevents siphoning - after filling the tank from the exterior fill port, several gallons of water can be siphoned out of the tank; the check valve stops that from happening.

The plug has a handle and uses an o-ring for the seal - no tool needed and no plumbers tape.
Note: this is NOT for the fresh water tank drain that is mounted underneath the van on newer models.

Update 02/13/2023 - I moved the check valve so that it no longer sticks up from the top of the fill plug - see latest images.
