FlowStop® – flow rate sensor and automatic isolator for water sustainability

FlowStop® is ideal for residential customers, landlords and property agents, student accommodation, hotels, offices and commercial premises

FlowStop® is an effective and sustainable water conservation solution, saving precious water, saving on water bills and protecting against the costly consequences of water damage from burst pipes, internal leaks and floods.

Cost-effective and WRAS approved, Andel FlowStop® automatically isolates your water supply in the event of abnormal flow activity or the risk of freezing pipess.

Andel launched FlowStop® in response to the growing requirement from insurers of residential properties to have a water supply leak and flood prevention system in place. FlowStop® provides a highly cost-effective and easy-to-install automatic water supply shut-off system, offering 24-hour protection against internal leaks and floods.

With FlowStop®, there is also the option to add leak detection sensors in vulnerable areas within a property such as kitchens and utility rooms with appliances using mains water such as washing machines and dishwashers and any other areas with running water such as bathrooms, toilets and sinks.

10 year warranty
Customers can enjoy the additional comfort of a 10-year warranty on all Floodline® leak detection, environmental monitoring and water sustainability products, at no extra cost.

UK insurers pay out around £1.8 million every day to customers making ‘escape of water’ claims on their buildings and home contents insurance. Nearly one in five claims is for damage caused by leaks with many in the winter months due to frozen pipes that have burst.
