is that the irrigation company blows out everything with pressurized air to winterize it.

  - Yes, backflow preventer/vacuum breaker. Ours was blown out with compressed air but - Grapeking 2014-04-26 00:40:38 (204 views)

- It'll do that every year unless you can shut it off inside and drain all that out. - -TJ_c5's 2014-04-15 10:52:57 (173 views)
  - I did shut it off inside. - QuattroFTW 2014-04-15 11:09:26 (211 views)
    - I shut mine off inside and open up all the zone drains + the manifold drain and leave it that way. - -TJ_c5's 2014-04-16 11:39:08 (172 views)
      - I think I was pretty lucky. I just shut it off inside, didn't drain or blow out. - QuattroFTW 2014-04-16 12:19:50 (174 views)
    - looks like a drain on the elbow before the PVB valve...should be easy enough to winterize next year - stickyTaco 2014-04-15 13:55:02 (177 views)
- Yes, they'll freeze and break if not winterized properly. The other thing that happens is that - Dave Doolittle 2014-04-15 10:50:10 (214 views)
  - Thanks, looks easy enough. Plenty of youtube videos on this. - QuattroFTW 2014-04-15 11:12:10 (186 views)
- Happened to mine as well, what color siding is that? I just did my house in Portsmouth Blue - Raistlin 2014-04-15 09:02:41 (192 views)
- Mine busted as well. Brass casing split open. Think I'll do as schlepper says. - Grapeking 2014-04-15 06:11:01 (168 views)
- Next winter just take it off and store it inside. - schlepper 2014-04-14 23:23:35 (192 views)
  - Shut water off. Pull the guts and leave the two valves half open and the flat head drains open. - stickyTaco 2014-04-15 00:19:24 (188 views)
    - That's what I do, with a strip of duct tape across the top so nothing crawls in. - kwilson 2014-04-15 15:02:49 (175 views)
