Key differences between First Alert L5 WiFi Water Leak Shutoff Valve and Frizzlife LP365-P

A summary of selected recorded differences between these water shutoff valves. Check the full specification table below for details and conditions.

Feature differences among your selected devices

Flow Sensor (leak protection): First Alert L5 WiFi Water Leak Shutoff Valve — No; Frizzlife LP365-P — Yes (Patented ultrasonic flow sensing with no moving parts, over a 0.001 to 18 GPM monitoring range, plus pipeline pressure on this version.).
Micro Leak Test (leak protection): First Alert L5 WiFi Water Leak Shutoff Valve — No; Frizzlife LP365-P — Yes (Detects flow changes down to 0.01 GPM and has an in-app Leak Test that checks the line while every fixture is off.).
Wired Leak Sensor (leak protection): First Alert L5 WiFi Water Leak Shutoff Valve — Yes (Includes a 5 ft sensing cable plugged into the actuator that shuts the water off when it detects a leak; more cables can be linked to extend coverage to 500 ft.); Frizzlife LP365-P — No (The LP365 has no leak sensor input; Frizzlife's wireless leak sensors are sold only with the separate LPG365 kit and are not compatible with the LP365.).
Battery Backup (power): First Alert L5 WiFi Water Leak Shutoff Valve — No (No battery is listed. During a power outage the manual says to unplug the actuator and use its emergency handle; that handle does not sync the valve state with the app.); Frizzlife LP365-P — Yes (When unplugged it runs on its internal battery, keeps monitoring water use and can still shut off the valve automatically; the app is only for remote control.).

Specifications to check side by side

Freeze Alerts (leak protection): First Alert L5 WiFi Water Leak Shutoff Valve — Sold separately (The valve has no temperature sensor of its own; freeze monitoring comes from a First Alert L1 WiFi Water Leak and Freeze Detector paired with it.); Frizzlife LP365-P — No (The pressure version replaces the pipeline temperature reading with pressure, so it has no temperature data to warn about freezing.).
Pipe Sizes (valve): First Alert L5 WiFi Water Leak Shutoff Valve — 1/2", 3/4", 1", 1-1/4" (Sold as VWS02Y-1/2, VWS02Y-3/4, VWS02Y-1 and VWS02Y-11/4, each with its own NPT ball valve.); Frizzlife LP365-P — 3/4", 1", 1-1/4" (The LP365-P is sold in a 1" NPT version that includes 3/4" adapters (1" & 3/4") and in a 1-1/4" version (1" & 1-1/4").).
