Header arrangement for 2 antifreeze zones

[Moshersprink]

Hi everyone, my first post here and want to thank everybody for the interesting Q&A on this site. I've been reading for a while

I'm looking at a situation where 2 small antifreeze zones are required (NFPA 13 occupancy). Each zone will be <20 Gallons. To reduce costs I'm wondering if it is possible to have the 2 zone control stations downstream of 1 RP backflow assembly?

Thanks!

What is your question exactly?

If you are asking whether one backflow assembly can supply two control valves, there is no reason why not.

Thanks. Seems like a dumb question but just wanted to be sure. I don't have a lot of experience with antifreeze systems and for some reason thought a separate RP backflow assembly might be required for each zone.
