It appears that I need an RPZ device anyway. Glad I asked a few questions. I will have two supplies, one from a holding tank that collects rain water, and the other the municipal system. I need a device that will prevent backflow pressure as well as siphoning. Any recommendations on which to use. I don't want to break the bank, but want something familiar and easy to maintain. I saw three brands in Sprinkler Warehouse, Febco, Conbraco and Wilkins. It's a 1" main line coming from the meter and to the meter for all that's worth.
I did find something very interesting reading up on them in their installation instructions. For all three, they say not to install them outside in areas that freeze. They said freezing conditions will damage the devices. All say to install inside and pipe to a drain in areas that freeze. Now, I'm not sure what to do. I realize it will be winterized and drained, but it doesn't mention this. They seem pretty strict on it.

Plumbing code stipulates that every device or assembly be supported with proper supports. This doesn't mean supported by the pipe itself. A 1" RPZ is a heavy assembly. Pipe 'feet' is a hack install, and a major problem waiting to happen.

All it takes is a PVC male and copper female and make place these joints under ground. You could even build "feet" into the copper pipe to support the backflow device without the risk of it getting knocked over and damaging the underground plumbing.

After everything is installed, don't forget to get it tested by an Authorized backflow assembly tester.
