Leak

[RKmoho]

This valve is under the vanity sink in our DEQ, anyone know what it’s for? It’s developed a small leak.

Ron, that looks like an Anti Siphon Valve which prevents contamination of the fresh water supply.

You can buy a better version at any decent hardware store or Home Depot.

Although my Anthem is still in production so I can't speak from direct Entegra experience, on my Monaco Diplomat, that device is installed on the fresh water line from the wet bay to the black tank flush sprayer.

As Matt stated, it's designed to prevent contamination of fresh water by providing positive separation between a fresh water source and a non-potable (your black tank) source.

Here's a link to a replacement: https://www.amazon.com/dp/B01F8Z62NU...detail_0?psc=1

You may be able to find a suitable replacement locally, or, you may just have to tighten the connections.

Take care,
