These are some examples of the RPA or the Reduced Pressure Assembly. These are the best mechanical type backflow prevention assembly out there. They are a little more expensive than the other assemblies, but they are more versatile and reliable. If you own a commercial property, by most City ordinances you are required to have this backflow assembly installed on your potable supply regardless of the type of business you own. This is also the only approved backflow assembly for indoor plumbing, mostly due to height restrictions on the PVB assembly, but also for the covered risk factors that come with some commercial properties. For residential applications you would want to install this assembly if you have raised irrigation heads or hos2 bibs attached to your irrigation system and can not or do not want to lower them. The RPA only has to be installed at a minimum of 12 inches above finished grade, but recommended to not be higher than 36 inches. If you are installing one these in a known flood zone, this needs to be taken into consideration as well. You will need to install the assembly above the highest flood stage for the area, again a minimum of 12 above the flood plain, but not more than 36 inches above. Knowing the application for which you are purchasing and installing a backflow assembly is one of the most critical aspects.
