Black tank vacuum breaker

[Harleyhop]

I know there have been many threads about this subject but here we go. I have 2014 Alpine 3500re and I have looked for vacumn breaker under bath vanity and under kitchen cabinet but it's not there. Any Alpine owners out there that have found theirs. Not that it's leaking knock on wood but would like to know....
Thanks in advance!

It may be behind the shower faucet. If you hook up a hose and run it, you should be able to hear water flow through it.

Not an Alpine owner but they often hide them behind the shower wall... pull the faucet block and look behind it.. As for it leaking, it's not if, it's when...
