The gulleys outside a house into which sinks and rain-water pipes discharge are in most cases left uncovered, with the result that many of them get blocked by leaves, and a heavy rainstorm often causes serious flooding.

It is a simple matter to make a gulley-cover out of sheet zinc or thin boards. On one side a semi-circular-ended notch is cut to enable the cover to be pushed up against the wall round the pipe. A wooden cover is prevented from shifting by slats nailed to the under side, at the right distance from the front and side edges to just enter the gulley. A zinc cover has its edges turned over except on the wall side, if the gulley is above ground level; or tongues cut in the sides and turned down, where the gulley is flush.
