Thanks, guys. I just bought the adapter; it will be here on Thursday, =
well ahead of any freezing temperatures.
John=E2=80=99s comment about a backflow preventer valve does have me =
rethinking one aspect of my plan. The system installer put in an =
outside hose barb that he intended for blowing out the system, but I had =
thought it made sense to move ahead of that and start where the system =
originates in the basement. I can isolate the sprinkler from the rest =
of the system and blow it out from there. Unless there is a good reason =
not to do it that. If there is a backflow preventer valve between the =
hose barb and the basement, might there be a problem blowing it out from =
there?
