Downstream system???

[Lost_Sailor15]

I purchased the stuff I need for kegging beer off of craigslist about a 1.5 years ago. I have been using it with no problems so far. I put in a new tapper for root beer and wasn't able to get it carbonated. I found out that I need to carbonate at 30 PSI for the root beer. Since I don't want my beer at that pressure I realized that I need to get another regulator. When I researching regulators, I found mine on the manufacturer's website. It is designed for beverage dispensing, but I was surprised when I saw it specifically said NOT FOR BEER. Anyway, I sent an email to the manufacturer with a few questions.

The question regarding not for beer was replied to with:

"It is not designed to protect downstream systems which you need for any beer system"

So, my question to all of you is, what is the definition of a "downstream system"

Thanks!

Downstream means whatever you have connected to the regulator that's recieving gas. This could mean kegs, secondary regulators, manifolds, etc.

Does your regulator have a pressure relief valve? If not, that's probably the protection she's referring to.

I'm not sure, but I think some regulators also prevent the flow of liquid into the regulator. So, if you created a vacuum somehow and caused your regulator to suck up beer, it wouldn't ruin the regulator. This is just what I've heard though, and I've done no further research on the matter, so I could be completely wrong...
