I bought the Melnor AquaTimer after my wife pointed out that I had killed half the petunias. I forgot to water them for three days while we were busy with weekend activities. She was not happy. I needed something that would water the flower beds on a schedule without me remembering to do it. The AquaTimer was the cheapest programmable timer I could find with decent reviews. Here is how it has worked for the past two seasons.
The AquaTimer is a hose-end programmable water timer. You screw it onto your spigot. You screw your hose onto it. You program when and how long it waters. Then you forget about it. It runs on two AA batteries and controls a single zone.
What the Melnor AquaTimer Brings to the Table
This is a single-outlet digital timer. The LCD screen shows the time, program settings, and battery level. You can set up to 4 separate watering cycles per day. Each cycle can run from 1 minute to 240 minutes. You can water every day, every few days, or on specific days of the week.

My Real-World Experience With the AquaTimer
Programming the timer took me about 10 minutes the first time. The instructions are clear but the button sequence is a little awkward. You set the current time first. Then you set each watering cycle. Start time. Duration. Frequency. Do that for up to 4 cycles. Press the set button and it starts running.
I set mine to water my flower beds for 20 minutes every morning at 6 AM. That is it. One cycle. The timer has been doing this reliably for two full seasons. I change the batteries once a year whether they need it or not. I have never had it fail to open or close the valve.
The rain delay feature is handy. When we get a good soaking rain, I press the rain delay button and the timer skips watering for 1 to 7 days. This saves water and prevents overwatering. You have to remember to press it though. The timer does not know it is raining.

What I Like About the Melnor AquaTimer
- Reliable valve operation — opens and closes on schedule, no sticking or leaking
- Simple programming — set it once and it runs forever, very little to mess up
- Four programs per day — morning and evening watering for different zones on one timer
- Rain delay saves water — skip a day or a week with one button press
- Clear LCD display — easy to read, shows battery level and program status
- Long battery life — one set of AA batteries lasts a full season
- Manual override button — water now without messing up the program
What Could Be Better
- Plastic hose connections — the threads can strip if you overtighten, be gentle
- Not WiFi enabled — you have to walk to the spigot to change settings or check status
- Single zone only — if you need to water different areas on different schedules, you need multiple timers
- Difficult to read in direct sunlight — the LCD screen washes out in bright sun
- No automatic rain sensor — the rain delay is manual, you have to press it yourself
Melnor AquaTimer vs Orbit Single-Outlet Timer
These are the two most popular budget hose timers. I have used both. The Melnor AquaTimer has a better LCD display and easier programming. The Orbit timer has slightly sturdier hose connections. Both are reliable when you treat them gently.
The Melnor wins on user interface. The Orbit wins on build quality of the housing. For most people the difference is small. Buy whichever is on sale. Just remember to bring both inside during freezing weather. Frozen water inside the valve will destroy any hose timer.
Is the Melnor AquaTimer Worth the Money?
Yes, for basic automated watering. At around $30 to $40, this timer does exactly what it promises. It turns water on and off on a schedule. Day after day. Season after season. If you need one zone of automatic watering for flower beds, a garden, or a small lawn area, the AquaTimer is all you need.
Who should get something else? If you need WiFi control from your phone, get a smart timer like the Rachio or Orbit B-hyve. If you need multiple zones, get a 2-zone or 4-zone timer. If you just need a mechanical timer for occasional use, a $15 dial timer will do the job.

Frequently Asked Questions
How do I program the Melnor AquaTimer?
Press the Set button to cycle through time, program, and frequency settings. Use the plus and minus buttons to change values. Set the current time first. Then set up to 4 watering programs. Each program needs a start time, duration, and frequency. Press Set again to confirm.
How long do the batteries last?
About one full season with regular use. Two AA alkaline batteries should last 6 to 9 months. Change them at the start of each watering season to be safe.
Can I use the AquaTimer with a sprinkler system?
Yes, for above-ground hose-end systems. You connect the timer to the spigot and the hose to the timer. You can connect a single sprinkler or a hose manifold to water multiple sprinklers from one timer.
Does the AquaTimer work with drip irrigation?
Yes. Connect your drip irrigation tubing to the timer output. The timer works with any hose-end watering system including drip irrigation, soaker hoses, and sprinklers.
Will the AquaTimer survive freezing temperatures?
No. Bring it inside before the first freeze. Water trapped inside the valve can freeze, expand, and crack the housing. This applies to all hose timers, not just the Melnor.
Is there a warranty?
Melnor offers a limited lifetime warranty on their products. Keep your receipt. Customer service is responsive if you have issues.
