Pipe from House to ground

Hi,

I am in Massachusetts and have a question about the pipe that runs from the house to the manifold in the ground.

I have a 1" pipe that exists the house just above the foundation. It runs through an RPZ and then to the ground into a manifold. Now, I live in an area that freezes. Don't I have to worry about the ground freezing and heaving the manifold up and breaking the RPZ or pipe?

Is this something I need to worry about?

As long as you blow out the system at the end of the season and drain it, you will be fine.
Winterize the RPZ also by opening the "drain valves" and leaving them open.
I assume like most sprinkler systems I see, you have a water shutoff from inside for the system.

For new homes in cold climates, the problem can be just the opposite. The soil that is backfilled along the foundation will settle, and make an install look way crooked.

Take the RPV inside in the winter. (Install unions). Blow out the water.

that sounds like the best answer to me. That way I don't have to worry that I left a little water in there, plus I don't have to worry about the pipe from the ground up changing height as the ground freezes.

thanks
