How to Install an Irrigation Timer on a Hose Bib (and What It Can Water)

Looking for a quick and affordable way to automate your watering? You don’t need a full irrigation system to get started. Installing an Irrigation Timer on a Hose Bib is a simple and effective solution. It’s perfect for homeowners, small gardens, or temporary watering needs on a job site.

What Is a Hose Bib Timer?

A hose bib timer (also called a faucet timer) attaches directly to your outdoor spigot. It automates your watering schedule, turning the water on and off at set times—so you don’t have to.

How to Install an Irrigation Timer on a Hose Bib

1. Screw on the Timer
   Start by screwing the timer onto your outdoor faucet (hose bib). Use thread seal tape if needed for a tighter fit.
2. Attach a Hose or Irrigation Line
   Connect a standard garden hose or a 1/2″ poly drip line directly to the timer. Many models have dual outlets, allowing two separate zones.
3. Program the Timer
   Set your watering days, duration, and frequency. Digital models are user-friendly and offer better flexibility.
4. Test Your Setup
   Turn it on manually to make sure everything flows and no leaks are present.

How Much Can It Water?

Most hose bibs can handle about 4–6 gallons per minute (GPM). That’s enough to run:

• Up to 200 feet of 1/2″ drip line with emitters (0.5–1 GPH each)
• A few small sprinklers or micro-spray heads, depending on your pressure and flow

Pro tip: Use a pressure regulator (usually 25–30 PSI) and a filter to protect your system from clogs and blowouts.

Recommended Lines and Fittings

• 1/2″ Poly Tubing – Ideal for medium-size gardens and shrub beds
• 1/4″ Drip Lines or Emitters – Great for pots, borders, and precision watering
• Soaker Hoses – Simple option for beds, though less efficient than drip
• EZ-connect fittings – Make layout changes fast and easy without glue or clamps

Final Thoughts

A hose bib timer setup is a cost-effective way to bring automation to smaller irrigation zones. It’s especially handy for seasonal beds, rental properties, or temporary installs during landscaping projects. Need help planning your setup or upgrading to a full system? That’s what we’re here for.
