PRODUCT HIGHLIGHTS
- The most complete out-of-the-box water-protection system Custos offers. Six components that work together to detect leaks, alert you instantly, and shut off your main valve automatically — even during a power outage.
- Three AquaSensor-S1 leak sensors — the right starting count for most single-family homes. Place one near the water heater, one in the laundry area, and one under a kitchen or bathroom sink.
- Smart Backup Battery included — what separates "Ultimate" from "Starter." When a winter freeze causes both a pipe break and a power outage at the same time, this kit still closes your main valve automatically for up to 24 hours.
- Tool-free DIY installation in about 15 minutes for the entire system. No plumber, no electrician, no permanent modification.
- Works without Wi-Fi. Devices communicate over the patented UBILINK@LoRa private mesh — Wi-Fi is used only for cloud uplink. Your protection stays online even if your home internet doesn't.
- 24/7 multi-channel alerts. Push notification, SMS, phone call, and email — all triggered the instant a leak is detected.
- No subscription required. All core features — alerts, app control, automations, and the insurance certificate — work with no monthly fee.
- 18-month warranty + lifetime technical support on every component.
