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
