AquaWarden went off at 2am when our dishwasher hose came loose mid-cycle. The app alert woke me up before it spread past the laundry room. Genuinely saved us from a much bigger mess.

Built To Catch What Other Detectors Miss
mic
Detects Water In Seconds
The sensor triggers the instant it touches water, not after it pools. That head start keeps a small drip from becoming a flooded basement.

Catch Patterns Before Repairs Add Up
Every alert is logged and time-stamped in the app. Spot patterns early and plan maintenance before small issues become big repairs.

Built For Every Room In Your Home
It performs from -10°C to 50°C, so basement damp, garage heat, or laundry humidity won't stop it. Place it near the sump pit, heater, or washer.

Check In With Alexa Or Google
Ask Alexa or Google Assistant to check your detector's status anytime. It's a quick way to stay in the loop without opening the app.

Based On Real and Honest Experiences
I'm on the road for work more than I'm home, so a local beep does nothing for me. AquaWarden pinged my phone the second it caught a leak near the water heater, and I called my neighbor to check it before I'd even landed.
Marcus ReillyVerified Buyer
I've been burned by cheap water alarms before, so I didn't expect much from AquaWarden. Two rainy seasons in, it's caught one slow drip near the sump pit and never false-alarmed on basement humidity. Now I sleep through storms instead of worrying about the basement.

Q1 Will basement humidity or condensation set off false alarms?
The alarm needs standing water to bridge its contacts, not merely damp air, so ordinary basement humidity won't set it off. For best results, keep it on a dry, flat spot away from constant drips or vents.
Q2 Can I check on my AquaWarden while I'm traveling?
Yes. The Smart Life app sends a push notification the moment water is detected, no matter where you are, so a leak while you're at work or on vacation won't go unnoticed until you're back.
Q3 What happens when the battery starts running low?
AquaWarden sends a voltage reminder to your phone while there's still time to swap it, so you're never caught with a dead battery. Like a smoke alarm, a quick yearly check keeps it ready for the moment it matters.
Q4 How loud is the alarm if a leak is detected?
The built-in siren hits 55dB right at the point of the leak, loud enough to notice if you're nearby or in an adjoining room. Pair that with the instant phone alert so you're covered even if you're upstairs or out of earshot.
Q5 Does AquaWarden work with voice assistants?
Yes. Ask Alexa or Google Assistant to check your detector's status anytime, no app required. It's handy when you want a quick answer without reaching for your phone.
Q6 Can I look back at past leak alerts?
Yes. AquaWarden keeps a timestamped record of every alert, so you can spot recurring issues and plan maintenance before they turn into costly repairs.
Q7 What temperature conditions can AquaWarden handle?
It's built to keep working from -10°C to 50°C (14°F to 122°F), so it performs the same in a chilly garage, a warm laundry closet, or a basement corner.
Q8 Why do some water sensors fail right when a real flood happens?
Most failures come down to a dead battery nobody noticed. AquaWarden sends a low-battery alert straight to your phone well before it dies, and logs every event in the app so you always know it's still watching.
