Nordic Quality Waterblock 3/4" Mechanical Flood Protection for Washing Machine and Dishwasher

The Nordic Quality Waterblock 3/4" is a mechanical shut-off valve for washing machines and dishwashers. It prevents water damage caused by overfilling by measuring the total volume of water passing through the inlet. If the flow exceeds a preset limit, the valve automatically shuts off the supply. The threshold can be adjusted between 5 and 50 litres to match the specific water requirements of the appliance.

The device is rated for water temperatures up to 70°C, making it compatible with both hot and cold water supplies. It uses a standard 3/4-inch threaded coupling for installation directly between the tap and the appliance supply hose. Its compact size is suitable for restricted spaces, such as those found behind integrated kitchen or laundry units. As a passive mechanical system, it operates without electricity, sensor calibration, or regular maintenance. The neutral grey casing is designed to remain unobtrusive when installed in visible areas.

• Aquastop functionality – provides an automatic shut-off to prevent flooding due to appliance failure.
• Mechanical system – operates via water pressure; no electrical connection required.
• Integrated reset – allows the device to be reactivated and reused after a shut-off.
• Manual dial – enables precise adjustment of the shut-off volume.
• Broad compatibility – fits standard water connections used by most domestic appliance manufacturers.
• Hose protection – stops the water supply if a downstream leak exceeds the set volume limit.
