Whats the best way to unblock a rain-water drain blocked with leaf mulch?
Take off the drain cover. The drain goes down a foot or so and will bend towards where there is usually some grass or soft earth. With rubber gloves on put your hand down and remove all the debris. It usually collects near the bend and if there is some rubble there it collects a lot easier. The water should then disappear. If it does not it is because the soakaway to which this drain probably goes is saturated due to the amount of rain we have had in a short time. It will eventually go. Drain rods might help but be careful as they could come unscrewed if you don’t keep on twisting them as you go.
