  • Regular price £26.00


The Waterblock is a device designed to offer safe protection against accidental flooding without the need for electricity. It incorporates a mechanical water meter which monitors a pre-set volume of water, and when the pre-set is exceeded the unit will close off the water supply. The Waterblock also has an integral filter system to guard against waterborne impurities. The unit is simple to install to any standard 3/4 BSP water connection and can be pre-set between 5-50 litres. When the Waterblock is activated to prevent flooding, it will stop the flow of water. Without the external reset device, it would require you to disassemble the Waterblock in order to reset it. The reset device allows for a quick and easy way to allow the water to flow again without having to take the assembly apart.
