Hunter dripline questions

Hey the guys,

I have a customer who hired me for maintenance of their property. They have asked me about winterizing their hunter drip-line system. I am not familiar with any irrigation but they are adamant about paying me and not the guy who installed it. I promised them I would look into it so here I am. I have some pics I have taken and was wondering if anyone could tell me anything about what I am getting myself into...... any information would be helpful. It is a drip-line that waters their shrubs along the perimeter of their property.

I'm getting dizzy standing on my head to look at the controller photo.

NEPA has sprinklers? Where?

Looks like one of those Hunter PCZ drip control zone kits, with the 1" PGV w/ flo, filter and fixed pressure regulator. We winterize drip zones on our systems, can take a while, is there a air/vac relief valve at the highest point or auto line flushing valves on the end of the runs or manifolds?

I remember reading somewhere that it is better to set the pressure regulator before the control valve since the pressure regulator can take time to adjust down and in that adjusting time the high pressure can blow the small drip fittings apart.

1. Just find the ends of the runs,
2. open them up,
3. blow as normal.
4. close ends back up
Not a big deal, just want to make sure you have step 2 complete.

dude, just cut the air to around 30 pounds and sit on the zone for 5 minutes, you'll be fine. your local irrigation contractor will slash your tires, but you won't blow anything up
