Where a line has failed more than once, replacement stops being the expensive option and becomes the cheap one.
Rerouting above ground or through a ceiling is often cheaper than digging the same trench twice. Diagnostics at Leak Detection Cape Town.

- Galvanised steel - pre-1970s homes. Corrodes internally, restricts flow, then fails. Replacement rather than repair.
- Copper - long-lived, but pinholes where water is aggressive or pressure is high.
- Polycop and PEX - current standard. Fails at fittings and where crushed, not along its length.
- Uncertain - a plumber can tell you in a minute at any exposed point.
Reroute Instead of Excavate
A mains run under a paved driveway can often be rerouted around the edge or brought overhead in far less time than it takes to break and reinstate the paving. It looks less tidy on a drawing and costs considerably less in practice.

Get the repipe quoted against two or three more patch repairs. On corroded galvanised, the replacement usually wins on a three-year view.

Frequently Asked Questions
How long does a full repipe take?
A typical three-bedroom home runs three to five working days, with water off for part of each day. Rerouting through ceilings and ducts is faster and less destructive than chasing walls.
Can pipes be replaced without breaking walls?
Often, yes. Rerouting through the roof space, along skirting ducts or externally avoids most chasing. It is the standard approach where the existing route is in a slab.
Is high water pressure damaging my pipes?
It can be. Cape Town mains pressure regularly exceeds what a domestic installation is designed for, and the by-law caps it at 400 kPa at the cylinder. A working pressure-reducing valve is the cheapest protection you can fit.
