Need valve adapter fix to connect faucet to open irrigation zone (almost working!)

post #1 of 3

So here's the issue... I have a 100ft stretch of grass on the outside of my fence and beyond the reach of my existing irrigation system.  Right now the only way to keep it watered is to run a hose (which currently has a dedicated Orbit timer on the faucet).  This doesn't feel like a permanent solution... plus I can't remotely manage the watering as I can with my primary irrigation (via IrrigationCaddy).  I have the 9th zone available on my system and was hoping to tie-in a faucet adapter that would activate via my controller.  This would also allow me to use the 9th zone as a "mobile" zone to focus on 1-off projects throughout my yard.  

Here's where I am so far... 
I purchased this valve: Orbit Yard Watering Valve 58874N 
http://www.orbitonline.com/products/Timers/01/04/04/437/


I cut off the end plug, exposing two wires.  I connected the black wire to my irrigation controller's 24V Common and the red wire to the controller's 9th zone terminal.  This almost does the job... as I was able to turn on the valve via my controller's interface for the 9th zone (water was running into the hose).  The problem was turning it off.  When I turned the zone off on my controller, it didn't shut the valve off.  It seems the valve needs a different instruction to deactivate.  So ON works... but OFF doesn't.  

Any chance one of you happen to be an electrical engineer and know of a relay that I could use or build to correctly handle the OFF instruction?  I'm soooo close!

That valve looks like it is meant to run on battery power (DC) and would either operate via forward/reverse polarity or timed operations or a combination of both. So by running 24VAC through it you may have damaged it. Otherwise you should test it with some batteries and see how it works. Hard to say whether the controller uses the battery voltage directly (3V) or boosts it first. Once you figure that out you can see what circuits are necessary for controlling it.

Otherwise you may want to consider using a proper 24VAC valve and adapting it to fit your hose.

Wow. Genuinely surprised I missed the source to actually be battery power (DC). This part connects to the timer (which contains a battery) via a wire, so I accidentally thought it to be an AC part.

Anyways, I scrapped the above parts and went with a dedicated sprinkler valve. Setup was pretty easy. Only hurdle was to convert the Garden Hose Thread to Pipe Thread. Fix was to buy two coiled faucet kink protectors, cut off an end on each (different end for each), fit them with 3/4-in male PEX adapters, and screw them onto the valve. Then I split the common on my irrigation controller to connect one wire, inserted the second wire into my 9th zone.... and voila, my hose is now integrated into my irrigation system. As I'm using IrrigationCaddy, I'm able to turn the hose on/off via my phone remotely. Works great as a mobile sprinkler for projects around the yard. Here's some picts:
