Older properties don't have one plumbing system. They have four, joined together by whoever came last.
Original copper. A galvanised section nobody replaced. Plastic added during a kitchen refit. A cast iron waste stack that predates all of it. The property works, but the pipework is a timeline — and every point where one material meets another is a joint someone had to make between two things that were never designed to meet.
Those transitions are where failures concentrate, and they're also where repairs go wrong.
Copper and steel joined without proper separation corrode from the inside at the junction. A plastic push-fit onto a corroded thread never quite seats. A repair made in whatever material the plumber prefers, rather than what the situation requires, becomes the next failure.
So the useful question is what your pipework actually is — and whether whoever's repairing it works comfortably in all of it, or reaches for the one thing they're used to.

The joints between materials deserve their own section, because they cause a disproportionate share of problems.
Dissimilar metals in contact with water corrode at the junction — from the inside, invisibly, until the joint fails. A direct connection is a slow failure with a start date.
Straightforward with the right fitting, and a common failure point when improvised. Different expansion behaviour, different support requirements.
The thread is rarely clean enough for a reliable seal.
Cast iron is heavy, and hanging new lightweight pipe off it without thought creates stress at the joint.
A health question rather than a plumbing one.
The remains of a compression fitting, or a section that's been over-tightened, ovalised, or scored.
A repair at a transition should be made deliberately, with the correct fitting — not by whatever adapter happened to be in the van. It's the difference between a joint that lasts and one that's on a countdown.
Pipe behaviour is not general. What you have determines what to expect.
Fails through pinhole corrosion — perforations from the inside, driven by water chemistry, high velocity, or aggressive flux left at joints. Pinholes rarely come alone, so finding one means the conditions that caused it apply to the rest of the run.
Corrodes internally over decades, narrowing the bore and rusting through. Symptoms arrive before leaks: reduced pressure and discoloured water at first draw. Threaded joints go first. Section repairs generally defer a repipe rather than avoid one.
Documented failure histories — degradation from within and failures at fittings. The material's presence changes the recommendation whether or not it has leaked yet.
Failures concentrate at fittings, in UV-exposed sections, and where rodents have had access. The pipe rarely fails mid-run.
Reliable but becomes brittle with age and heat, failing at joints and where badly supported.
Corrodes from the inside, scales, and eventually perforates. Slow, progressive, predictable.
Replacement regardless of condition.
Most failures are at connections rather than mid-run: compression fittings that have relaxed, soldered joints made poorly, push-fits not fully seated, and corroded threads.
A leak is not always a pipe. Failed seals, waste connections, appliance hoses, shower trays, and heating components all present as water where pipework runs.
The question that decides whether you'll be calling again.
A screw or nail through a pipe during other work. A joint disturbed by another trade. A single unheated section that froze. Repair it, and there's no reason to expect the neighbour joint to follow.
The pipe failed because of what it's made of, how old it is, what water has run through it, and what pressure it's held. Every other joint on that run has had the same experience.
How to tell them apart:
You're entitled to be told which, with the evidence from what came out.
An ice plug forms in an unheated run. Water is trapped between that plug and the nearest closed tap, and pressure rises until the pipe splits. The split is caused by pressure, not ice against the wall.
The split stays sealed by ice while frozen and releases on the thaw.
Locate your main, open taps to relieve pressure, warm the area gently, and never use a naked flame.
Main off, lowest taps opened, power off to anything the water is reaching, and call.
Everything in that unheated run had identical conditions. Finding one split is a reason to check the whole length — and different materials fail differently under freeze, which affects what you're looking for.
Where a specific connection failed on sound pipe.
New pipe, properly jointed at each end — and matched appropriately to what's there, with the correct transition fitting where materials change.
Where the run's condition rather than one point is the problem.
Avoiding reopening a slab or wall.
Where the evidence supports it.
Stop water immediately, work on a wet pipe, buy you daylight. Not permanent on pressurised supply.
Useful on a weep while you wait. They don't restore a failing pipe wall.
Copper, galvanised, PEX, CPVC, cast iron, and the transitions between them — so the repair suits your pipework rather than our preference.
Dielectric fittings where dissimilar metals meet, correct couplings on cast iron, cutting back to sound material rather than fighting a corroded thread.
Particularly useful in a property you've recently bought, where nobody has ever told you what's in the walls.
Because a repaired joint on a finished pipe is a bill you'll be paying again.
Corrosion, wall thickness, and the condition of the cut section are the evidence behind the recommendation.
One split means everything in that unheated section had the same experience.

Dissimilar metals in contact with water corrode at the junction, from the inside, invisibly. The correct transition uses a dielectric fitting to separate them. A direct connection is a slow failure with a start date.
We'll tell you, and it's genuinely worth knowing — particularly in a property you've recently bought. Copper, galvanised steel, PEX, CPVC, and cast iron all behave differently and fail differently, and identifying yours makes every future decision faster.
Pinhole corrosion, driven by water chemistry, velocity, or flux residue — all affecting the whole run rather than that spot. Pinholes rarely arrive alone.
It corrodes from the inside over decades, narrowing the bore and eventually rusting through. Symptoms show as reduced pressure and rusty water at first draw before anything leaks. Section repairs generally defer a repipe rather than avoid one.
A corrosion signal, and frequently a sign of galvanised steel. It's worth having the material identified, because it changes what to expect over the next few years.
It's a make-safe, and a legitimate one at midnight. It isn't permanent on pressurised supply — the rubber ages and the pipe underneath keeps corroding. If nobody told you it was temporary, that's the problem rather than the clamp.
Depends why it failed. If something specific happened at that point, it's local. If nobody can name a reason, the rest of the run has the same age, material, and water history.
That's the normal sequence. Ice traps water against a closed tap, pressure rises until the pipe splits, and the split stays sealed until the thaw.
Yes. Everything in that unheated run experienced the same conditions, and different materials fail differently — which affects what to look for.
Rarely, and only where the evidence supports it: a material with a known failure history, repeated failures, or visible corrosion throughout. It's a real recommendation in some properties and oversold in others.
Usually water hammer or inadequate support. Not immediately dangerous, but it stresses joints over time — particularly at transitions — and it's straightforward to address.
Most older properties are four plumbing systems joined by whoever came last, and the joints between them are where failures concentrate. Copper meeting steel without separation, plastic onto a corroded thread, new pipe hung off cast iron — each one is a repair someone made in whatever they had rather than what the situation needed.
