Common causes of burst pipes in Pretoria homes
Older copper pipes corrode from the inside out, eventually rupturing at weak points — typically inside roof cavities or behind tiled walls. PVC and PEX lines can fail at fittings if originally over-tightened or exposed to UV. Galvanised steel pipes, common in older Pretoria suburbs, rust internally and split along seams.
Pressure spikes from the municipal supply, ground movement, freezing temperatures in higher-lying suburbs and DIY-installed fittings are other frequent causes we see.
