You follow the manufacturer instructions. If you have an outdoor meter pit, with room in the pit to tee off to the sprinkler system, you'd include a drain valve in your plumbing.

I figure if I get the water out of the RPZ, then I wont have to worry about it freezing and damaging the unit, thus avoiding having to install unions at the RPZ.

If the blowout is installed after the RPZ, what do you do about clearing the water out of the RPZ for the winter months?

I am also leery about open lines (open drains are okay) and prefer to do what it takes to make sure water doesn't remain to freeze.

Putting the blowout after the RPZ has been the customary arrangement. Some of the newer ones are more easily blown out through the RPZ, without the relief valve opening up.

Blowout

In searching through messages I see conflicting information on where to install the blowout for the system. Some posts say to place the blowout before the vac breaker, and others after.

I am also wondering what people do if they installl unions to be able to remove the vac breaker in the winter months. Since it doesn't seem that they make caps for unions, do people leave the pipes open ended for the winter, or is something else done. I would be kind of leary about leaving my mainline open for the winter months.


If it makes any difference I am going to be installing a RPZ valve.
