Features

  • Operates 2 sprinkler valves independently on one set of field wires

  • Quick repair prevents downtime and landscape damage
  • Easy to install - Completely waterproof

Description

DOUBLER Doubler allows independent control of two automatic valves with only one valve wire and the common. When Doubler is connected to one station of the controller, it switches when the station is turned on and passes the electrical current to the first valve. The next time that station is turned on, Doubler switches to the second valve. It simply alternates between the two valves. If two stations are connected to Doubler by a jumper wire in the controller, it switches between the two valves corresponding to the two stations. It simply uses one wire twice. If a second station is not available, use another program to power the added valve. Each valve will water for as long as the time set on the controller. The industry standard for bypassing broken wires and adding new valves without the need to trench new wire back to your controller. DOUBLER allows the independent operation of two valves on one set of field wires. Add a valve to separate wet and dry areas. Operate 2 valves separately on one wire. Bypass broken wires. Divide low pressure lines by adding more valves. Add new valves to a full controller by using additional programs. Add a drip line without trenching more wires. Completely waterproof for direct burial. No disturbing your landscaping. Compatible with all controllers using self diagnostic circuitry. Switches before turning on a valve, not after. No damage from short circuits up to 10 amps. Info (173 KB) Inst (63 KB) Test (27 KB) Spec 1 (32 KB) Spec 2 (36 KB)

  • Works Perfectly For My Situation!
I had been struggling with watering 2 Front Yard zones up until I found this Doubler. My system has been hit by lightning twice and now only one hot wire runs to my front yard two zones. They have been tied together but one zone is sprayers and the other is rotary, so the water volume is vastly different. I couldn’t adjust to get the same amount in both zones. I am now using the Doubler and it works perfectly. I can now independently set the time for both zones using the same hot wire. Amazing! It is expensive but it is made in the USA and well worth it for my situation. ... show more

  • Great item if you lose a wired Irrigation Zone
I was very happy to find this. No one sells them where I live. They want you to buy a whole new system. This is easy to connect and you just run same zone twice A and B on your clock. It switches great and you have water again to the zone that is failed (wires) . You can buy these with 2, 4, 6 zones if need be. DIY person can do this. Remember to buy the sealing wire nuts ... show more

  • Worthless item! Same as wiring 2 valves together in the controller box!
It does’t provide any benefit! You can just wire 2 wires together instead of using the Doubler. That’s the reason they don’t except returns, people figure out that they don’t need it. It’s useless, why spend the money. I never even took mine out of the box!

  • It works, but why so pricey?
I purchased this item to bypass a bad wire in the bundle that goes to my backyard irrigation valves. It works as described and is easy to install. I would give it 5 stars if it was priced in the $20-40 range, as I think it should be, considering the materials and technology involved. Nevertheless, it saves much more than that considering the alternative of replacing a hundred feet of underground wire. So, I would purchase again in a similar situation. ... show more

  • Listen up...these actually work... like a charm
Run out of wires and want to add another zone to your sprinkler configuration? Don't dig and run a new wire. Get these, they are great and simple to install. Not cheap, but worth the price to avoid a lot of work.
