PlumBuddy Valve Specifications

Overview

The PlumBuddy Valve is a motorized smart water shut-off valve that installs on your main water supply line. It monitors water flow continuously and can automatically shut off your water supply when a leak is detected. The valve is controlled through the PlumBuddy mobile app and connects to your home network via WiFi.

Valve Sizes

PlumBuddy valves are available in three sizes to fit different residential water line configurations:

Valve Size	Pipe Size	Connection Size (NPS)
DN20	3/4”	1”
DN25	1”	1-1/4”
DN32	1-1/4”	1-1/2”

The DN25 (1”) valve is the most common for single-family homes. Your plumber can help determine the correct size based on your home’s main water line diameter.

Materials and Construction

Valve body material: DZR (Dezincification Resistant) Brass
Control interface: On/Off buttons under swivel top cover
Indicator light: Multi-color LED for status indication
Antenna: Built-in for WiFi connectivity

DZR brass is specifically designed for use in potable water systems. It resists corrosion and dezincification, which means the valve body will hold up to years of continuous contact with your home’s water supply.

Power

Primary power: USB-C (5-12V) connected to a standard 120V outlet using the included adapter
Power cable length: 10 feet (included)
Backup battery: Internal 19,000 mAh lithium-ion battery
Battery backup runtime: Approximately 1 to 7 days depending on usage

The valve requires a power outlet within 10 feet of the installation location. If your installation requires a longer cable, contact PlumBuddy support for guidance on compatible USB-C cables and power parameters.

Battery Backup

The internal battery provides backup power during outages. When running on battery, the valve retains its current state and can still open or close if needed. Once AC power is restored, the battery recharges automatically.

Pressure and Temperature

Maximum operating pressure: 1.6 MPa / 232 PSI
Water operating temperature: 0 degrees C to 70 degrees C (32 degrees F to 158 degrees F)

These ranges cover standard residential water supply conditions. If your home has exceptionally high water pressure, a pressure reducing valve (PRV) upstream of the PlumBuddy valve is recommended.

Wireless Connectivity

WiFi standard: 802.11 b/g/n
Frequency: 2.4 GHz only (5 GHz is not supported)
Recommended range: Within 100 feet of WiFi router

The valve does not support 5 GHz WiFi. This is intentional — 2.4 GHz provides better range and wall penetration, which is important for a device typically installed in basements, utility closets, or garages.

Installation

Installation type: Professional installation by a licensed plumber required
Orientation: Horizontal installation preferred for best flow detection accuracy; vertical installation is possible
Flow direction: Arrow marking on valve body indicates correct flow direction
Minimum height: 18 inches above grade recommended when installed on a slab or low entry point
