  • Operates 2 sprinkler valves independently on one set of field wires
  • Most cost effective way to repair broken wires
  • Bypass broken sprinkler valve wires - No need to trench in new wires from controller to valve
  • Quick repair prevents downtime and landscape damage

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)

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.

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

Relatively easy fix
How can a small switching device be a good value when it costs over $100? This electronic device can save you hundreds of dollars if you have certain problems with your irrigation system. I had a sprinkler zone dysfunction because something caused the hot wire to go dead somewhere underground between the controller and the solenoid valve. I didn't have to try and find the problem in the 100 feet of underground wire because of the Doubler. I was fortunate to have another solenoid valve next to the one that needed a new source of electricity, and it had a functioning hot wire. I just hooked up the Doubler as instructed in the user manual and solved the problem, saving hundreds of dollars in troubleshooting or placing a new hot wire for 100 feet underground. (The following is an added edit. It's important to run a third zone in between the two zones hooked up to the doubler, otherwise you just water the first zone twice because it doesn't shut off to let the second zone water.) You could also use this device to add another sprinkler zone to your system without laying long runs of wire to the new valve. It's worth every penny you will spend for it. ... show more

Wow! It actually works!
Had a valve that would not turn on. I replaced the valve, replaced the solenoid, still not working. Switched hot wires with a different valve, the broken valve was now working, so I knew it was an electrical problem. But to run a new wire would be difficult and destroy a lot of landscaping. Googled around and found The Doubler. The sprinkler repair guy wanted $150 just to come out, so I thought I'd give this a try. It took me 10 minutes to install, and it ACTUALLY worked! Highly recommend The Doubler! ... show more

Saved me $1500+
I have never left a review for any purchase. But I had a cut wire, and I was given a quote of $1500+ to fix the issue. I fixed it in 5 minutes with this device. As long as you have another valve very close.

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

Great solution for a broken sprinkler wire or adding a new zone
Did exactly what it was supposed to do. I wanted to split a zone into two. Thought I had enough wires, but it turns out the unused wire that I was planning on using was broken somewhere within the house walls. My options were to try this out or run a new cable on the outside of the house which would have been a huge hassle. This solution was very straight forward to install and the directions were accurate. It was more expensive than I maybe thought it should be, but considering the time it saved, it was well worth it. ... show more

Easy install
Easy to install and worked just as advertised. Great alternative to trying to rewire a large section.
