Impact damage (holes/deformation) on downpipe

Cause

Stones thrown up by lawnmowers, vehicles 

Repair

  • for a PVC downpipe, glue a piece of PVC over the hole using a PVC solvent glue; for metal, rivet and seal a metal patch over the hole
  • where the hole is large, replace the downpipe
  • if a dent or small deformation in a galvanised downpipe is not serious, it can be left
  • if the downpipe is leaking water, replace it; small holes may be covered with duct tape as a temporary repair
