Dallas Drip Irrigation- Do I need to blowout for the winter?


We just moved from Colorado this summer. I am new to both Drip irrigation and milder winters... I just installed some Drip irrigation, so do,we need to blow it out for the winter here in Dallas? My 1/2" poly lines are not buried, but just under some cedar mulch. I was not sure if that was enough protection from freezing or not? We always blew out our systems in CO with compressed air in mid October and never really started them up until May, so I am in a whole new world here.

Thanks for any help

Yes, Dallas does get cold enough for water to freeze within piping that is installed at grade, or has shallow burial depths. Observe the elevation at your zone(s)/system point of connection. If the elevation is higher, you might be lucky enough to get by adding a flush valve (PVC ball valve, or a figure 8 closing clamp) at the end(s) or farthest sections of the zone(s).
If you are not sure hire a Licensed Irrigator to review your issue(s), and recommend a suitable course of corrective action.
