Our inflatable devices are custom-made to fit your door’s frame and create a high-pressure, sealed barrier in any framed opening, preventing water from entering.

The pump is provided free of charge with your purchase, i.e., 1 HP2 pump for every 5 FlowStops. However, in the event of breakage or loss, inflation can be carried out using a standard or electric pump. The nozzle to be used is the same as for inflatable stand-up paddle boards or canoes and kayaks.

Flowstops are inflated at 15 PSI pressure. At such pressure, even in extreme temperature differences, the pressure is such that there is no alteration of the shape or resistance. We tested Flowstops at 167f without any problem.

– The device can remain in place and function correctly for 2 to 3 weeks.

– Beyond that, we cannot guarantee that it will remain watertight and resistant.

– It is essential to inform the user that the pressure must be checked every 2 weeks.

Standard sizes that we carry in stock ship within 3 days; depending on the size you need, custom sizes can take up to 12 weeks to produce.

Once your FlowStop device is deflated, you can store it rolled up or leave it slightly inflated to retain its shape if you have enough space.

-FlowStop barriers must be stored in a location where the temperature does not exceed 60°C. Exposure to temperatures above this threshold may affect the materials, performance, and warranty of the products. FlowStop barriers must be stored in a dry place, away from direct sunlight and heat sources. Outdoor storage is strictly prohibited to prevent damage to the FlowStop.

There is no need to re-inflate it regularly.

– The device is resistant to sunlight and heat, but excessive exposure during prolonged periods of high temperatures can cause an increase in internal pressure, putting stress on the bonds and seams, which may result in slight leaks.

– Prolonged use in high temperatures or direct sunlight may reduce the product’s durability.

FlowStop solutions remain effective at preventing water from entering through openings (doors, windows, garages, etc.). However, if water stagnates for more than three days during a flood, their effectiveness also depends on the overall watertightness of the building.

If the building has weak points (old walls, cracks, pipework, non-watertight floor slabs), or in the event of high water pressure, water may seep in via other routes. Furthermore, FlowStop devices do not address water rising from the ground or through the walls.

This type of problem requires additional solutions specific to the building’s structure.

In the event of prolonged flooding and therefore potential water ingress through walls and/or floors, or if the water level exceeds the height of the waterproofing joint, the pumps take over by draining the water outwards. They thus provide an additional safety measure to minimise risks and effectively protect the building.
