Plumbing / Project guide

Domestic water repiping

Prepare a shared-building repiping project with a clear view of the affected water distribution, occupied spaces and repair history. Ask the provider to explain investigation, replacement boundaries and how service will be restored between stages.

The decision this helps you make

What to aim for.

A comparable repiping scope with defined access, shutdowns, reinstatement and responsibility for the completed system.

Start with the information below, then choose your property type for the access, operating and decision-making details that shape the project.

Define the scope.

  • Identify the buildings, risers or distribution zones being considered for replacement.
  • Distinguish shared distribution work from fixtures or branches controlled by individual occupants.
  • Ask how the proposed sequence maintains access and manages interruptions to water service.

Put these records together.

  • Collect available plumbing drawings, repair invoices and a dated history of recurring failures.
  • Share prior assessments and identify modifications made since the drawings were produced.
  • Provide occupied-unit counts, access contacts and restrictions that affect investigation or installation.

Choose your property type.

Ask for a comparable proposal.

  • Define replacement boundaries, materials proposed and the assumptions about concealed pipe routes.
  • Separate opening-up, pipe work, testing and reinstatement so responsibilities can be compared.
  • Ask for a shutdown sequence and the process for communicating changes during construction.

Understand what affects the cost.

Ask providers to price the same scope and explain the assumptions behind these items.

  • The length and accessibility of distribution routes and the number of occupied spaces involved.
  • Concealed conditions, finish restoration and the work needed to reach shared piping.
  • The number of phases and interruptions required to accommodate building operations.

Project: Domestic water repiping

Agree on the handover.

  • Obtain updated drawings or marked records showing the routes and equipment changed.
  • Keep the provider’s testing, completion and product records with the building maintenance file.
  • Record unresolved items, warranty contacts and the process for reporting post-project concerns.

Questions before you begin.

Does a history of leaks mean the whole system needs replacement?

Ask a qualified provider to assess the pattern and explain the evidence for replacement, targeted repair or further investigation. Supply the repair history so the recommendation addresses the actual system.

How should we compare different shutdown plans?

Ask each provider to show affected areas, expected interruption windows, restoration arrangements and notice responsibilities. Compare the practical effect on occupants alongside the proposed construction sequence and price.

Continue planning.
