Can Alu-Rex eavestrough fastening system and gutter covers withstand heavy water flow?
Even if all the perforations get covered-which never happens because the wind sweeps away leaves and debris-Alu-Rex eavestrough fastening system and eavestrough cover leaf guard can drain up to three times the quantity of water ever recorded in the heaviest rainstorm. How? Because wet leaves remain permeable. Water still gets between the leaves-and even through them-to drain into the eavestrough. The water always finds its way into the holes. What’s more, the exclusive design of Alu-Rex products features an approximately half inch (1 cm) deep basin. Testing in the lab and in the field has shown this to be the right depth to catch more water without stopping the wind from doing its job of sweeping away leaves, pine needles, and debris from the surface. Beware of look-alike products that are completely flat. Water can overflow when products are not equipped with a basin.
