Burst pipe plumber Traralgon

Why pipes burst in a Traralgon winter

Water expands when it freezes, and a pipe that freezes full of water splits along its length — often a hairline crack that only shows when it thaws. The Latrobe Valley gets cold, clear winter nights, and the pipes that freeze are the ones exposed to the weather: outdoor taps, hose bibs, pipes on the cold south side of older weatherboard walls, and runs through unlined subfloors. The older weatherboard stock near the Traralgon CBD is the most exposed, but the newer estates are not immune where plumbing runs through unheated roof spaces.

Galvanised, copper and PVC — different bursts

Galvanised supply lines in the older homes rust from the inside and split at a thin section or a rusted thread. Copper splits on a freeze or at a poorly soldered joint. PVC and PEX — common in the newer estates — handles a freeze better than metal but will split at a fitting or a kink if the run was installed under stress. We match the repair to the existing material (or upgrade it where the old material is the problem) and we do not mix metals in a way that sets up galvanic corrosion.

Finding a hidden burst

Not every burst is visible. A drop in pressure, a hiss behind a wall, a damp patch on a ceiling, or an unexplained jump in the water bill can all be a slow burst inside a wall, under a floor, or under a slab. We isolate, pressure-test the house in sections to narrow the leak down, and use leak detection to find the exact spot before we cut into a wall or lift a floor. We do not guess and we do not cut more than we need to.

The repair

Once the burst is found, the repair is usually quick: cut out the split section, join in new material with the right fittings, pressure-test, and sign the supply back on. Where a whole galvanised run is rusted, we will tell you a partial repair is false economy and quote a line replacement. Where a single joint has failed on otherwise sound copper, we replace the joint — not the line. The price follows the actual job, not a worst-case assumption.

Preventing the next one

• Lag exposed pipes and outdoor taps before winter — the cheapest prevention there is.
• Isolate and drain outdoor hoses and irrigation before the first frost.
• Know where your water meter is and check the handle turns now, not during a burst.
• If a tap has frozen, turn the water off and call before it thaws into a burst.
• Replace galvanised supply runs that are past their life — they fail on the coldest nights.

After the repair — pressure test and sign-off

Once the burst is repaired we do not just turn the water back on and leave. We pressure-test the repaired section with the supply isolated, confirm the joint or the fitting holds, then sign the supply back on and check every outlet on the run for a secondary leak — because a hard freeze or a pressure surge that split one pipe can have weakened another. We lag any newly exposed copper, check the tempering valve and the hot water unit for damage, and on the older weatherboard homes we will flag any other exposed runs that are likely to be the next failure. A burst is often the warning that a whole run is past its life, and we will tell you when a one-metre repair is the fix and when the rest of the line is on borrowed time.
