100% Battery-Free Irrigation Control with Pre-Installed Valve
The DIG LEIT Solar Timer with 3/4″ Valve (LEIT ILV075) is the world’s first fully sustainable, single-station irrigation controller. Designed for maximum convenience, this robust timer comes with a 3/4″ Female Pipe Thread (FPT) in-line valve already pre-installed. There is absolutely no wiring required! Powered entirely by surrounding ambient daylight, it requires no direct sunlight, zero AC power, and no backup batteries to operate. This makes it the ultimate maintenance-free automation solution for remote gardens, median strips, and off-grid landscapes.
Beyond its innovative power source and easy inline installation, the LEIT Timer features a power-saving LCD screen that can be easily removed from the valve body for comfortable programming in your hands. It offers extensive scheduling flexibility with up to 5 start times per day, run durations up to 6 hours, and manual operation capabilities. It also includes an advanced monthly seasonal adjustment feature (0-200%) and non-volatile memory to safely retain your programming indefinitely. By pairing this unit with a 3/4″ irrigation filter and pressure regulator, you can build a highly reliable, commercial-grade drip zone anywhere.
- No Batteries or Wiring: Operates flawlessly on ambient light. The valve and solenoid are pre-installed, meaning you never have to splice wires or change batteries again.
- 3/4″ Valve Included: Features a high-quality 3/4″ FPT valve with a built-in flow control handle, supporting flow ranges from 0.1 to 25 GPM.
- Removable Faceplate: The timer easily detaches from the valve body, allowing you to program your watering schedules comfortably before reattaching it.
- Advanced Scheduling: Offers up to 5 start times per day, 1-minute to 6-hour durations, and global seasonal adjustments from 0-200%.
- Non-Volatile Memory: Safely retains all of your programmed schedules indefinitely, even if the unit is stored in complete darkness during the off-season.

Get your battery-free irrigation zone running in a few simple steps.
Step 1: Program the Timer (Optional)
Before installation, you can slide the LCD timer unit off the valve body. Because it runs on ambient light, you can easily program your current time, watering days, and run times comfortably in your hands, then slide it back on.
Step 2: Plumb the Valve
Thread the pre-installed 3/4″ FPT valve into your irrigation mainline. Ensure the directional flow arrows on the side of the valve body point downstream toward your emitters.
Step 3: Ensure Light Exposure
The unit must be installed above ground or in a location where the photovoltaic panel on the top of the timer receives ambient daytime light. Do not bury it in a dark underground valve box with a solid lid.
Step 4: Adjust Flow Control
Once installed and pressurized, use the built-in flow control handle on the valve to finely tune the water flow and pressure passing into your downstream irrigation or drip lines.
