PLUMBING HELP, WHEN IT MATTERS

Water leaks and burst pipes

Find the right next step for a visible leak, wet wall, burst pipe or weak water flow. Understand what leak detection and pipe repair include.

01

Quick answer

  1. Report where water appears and whether it is still flowing.
  2. Use a known water shutoff only if it is safe to reach.
  3. Keep clear of flooding near electricity and call to discuss the next step.
02

Burst or frozen pipe symptoms

A sudden flow of water or an exposed split pipe needs prompt attention. Little or no flow in freezing conditions can have several causes and does not identify exactly where a pipe is frozen. Do not use an open flame to thaw plumbing. Keep away from wet electrical equipment; use a known water shutoff only when safely accessible. Once a burst is controlled, the repair must address the damaged section and the conditions that contributed to it.

For an active break, use the burst-pipe checklist for safe call preparation and questions about access, repair checks and restoration.

For seasonal preparation, the winter plumbing checklist covers exposed pipes, outdoor fixtures and questions before leaving a property empty.

How leak investigations differ

Compare the details for each symptom below.

EvidenceWhat it helps withWhat it cannot prove alone
Meter movement when intentional use is stoppedIndicates unexplained water use that needs checkingThe location of a leak; automatic appliances or irrigation can also use water.
Moisture readings or thermal patternsNarrow an area for further investigationThe exact pipe defect or repair scope.
Acoustic or pressure testingEvaluate selected parts of a supply systemEvery hidden leak under every material or access condition.
Opening a surfaceAllow direct inspection where evidence pointsThat unrelated concealed areas are sound.
04

Low pressure is not the same as a leak

One weak tap can point to a fixture restriction. Several fixtures with weak flow can involve the supply, valves, a regulator or another shared issue. Compare hot versus cold and one fixture versus the whole property. Ask the water utility about a known interruption if nearby properties are also affected. Do not assume that repiping is needed without measurements and an explanation of the cause.

The low-pressure and weak-flow guide helps you compare one outlet with a property-wide change and prepare utility or measurement questions.

05

Keep a simple incident record

  1. Note the date, room and whether water use or weather triggers the symptom.
  2. Save safe-distance photographs of visible damage and previous repair invoices.
  3. List shutoffs used and whether the flow stopped.
  4. Ask where investigative openings are proposed and who repairs finishes.
  5. Request a clear finding, repair scope and post-repair test description.
Does leak detection include fixing the pipe?

Not necessarily. Investigation, access, pipe repair, drying and surface restoration may be separate charges or trades. Ask the provider to identify each part of the proposed work and how any uncertain scope will be authorized.

07

A wet ceiling does not tell you which pipe is leaking

Water can travel before it becomes visible. Note the room above, recent use of showers or appliances, and whether the mark changes after rain. These observations help narrow the investigation; they are not a reason to open the ceiling yourself. Stay away from a bulging or sagging water-damaged surface.

Ask the investigator where they propose to inspect first and why. Agree how openings will be authorized and whether the quote includes making them good. Leak detection, pipe repair and drying are separate scopes unless the quote says otherwise.

08

When does a small repair become a repiping decision?

Ask for evidence that the problem extends beyond the failed section. A history of leaks in different locations, findings from accessible pipework and the condition of connections are more informative than age alone. A localized defect and widespread deterioration call for different conversations.

Compare the branches included, any pipework left in place, access holes, testing and finish repairs. If the immediate leak needs isolating first, ask for that work to be described separately from a larger proposed replacement.

Should I book leak detection for low water pressure?

Explain whether the problem affects one tap or the whole property, and hot water, cold water or both. Low flow can have several causes. Ask for an assessment of the symptom rather than assuming a hidden leak or agreeing to repiping without supporting findings.

Water-line and leak guidance by city

A utility leak report, a concealed-pipe investigation and a private service-line repair are different requests. These local guides explain responsibility and assessment questions.

If the concern is unexpected recorded water use, use the water-meter reading checklist to keep the time, units and known equipment use together before arranging an investigation.
