Replacing pool pipework

Pipes are buried and forgotten until they leak or restrict flow. Replacing them means opening the ground, so it pays to plan carefully.

Pool pipework can fail through joint leaks, cracks from ground movement, root intrusion, or damage from later works such as landscaping. Some older pools also have undersized pipes that restrict flow, making pumps work harder. Pressure testing isolates which lines are faulty, and leak location narrows down where.

Equipment guides are about choosing, sizing and installing plant, not about day-to-day pool care.

Replacement may be local — exposing and repairing one section — or a full re-pipe of a line. Decks and paving are lifted and reinstated, so routes are chosen to minimise disruption. New pipes are pressure tested before burial and their routes recorded.

01Summary

What matters most here

  • Test before digging

    Pressure tests find faulty lines.

  • Local or full

    Repair a section or replace a line.

  • Record new routes

    For future reference.

02Detail

The work

  • Diagnosis

    Each line is isolated and pressure tested; a line that will not hold pressure is then traced to narrow down where the fault lies.

  • Excavation

    Lifting deck or paving along the route.

  • Replacement

    New pipe and fittings, correctly sized.

  • Testing

    Pressure testing before backfill.

  • Reinstatement

    Relaying deck and paving.

03Before you start

Before work

  • Find original drawings

    Of pipe routes.

  • Agree reinstatement

    Matching deck materials.

  • Consider resizing

    If flow is restricted.

—In practice

How to use this

Pressure-test each line to identify the faulty ones before opening the ground. Plan replacement routes, considering whether to upsize pipes, reduce bends and protect against roots. Lay the new pipes with access points for future repairs, test them before backfilling, and record their routes on a drawing.

Mistakes worth avoiding

Replacing everything without testing
Testing shows which lines actually need replacing. Without it, sound pipes are dug up and paid for unnecessarily.
No record of new routes
Unrecorded routes make every future repair harder. A simple drawing kept with the pool documents saves digging later.

04FAQ

Common questions about this

Can a pipe be fixed without digging?
Some lining methods exist; most repairs need access.
Will my deck be damaged?
Sections are lifted and relaid; matching materials matter.
Why resize pipes?
Larger pipes reduce resistance and help the pump.
How are new pipes tested?
By holding pressure before backfilling.
Can tree roots damage pool pipes?
Yes. Roots can crack joints or enter pipes, which is one reason planting is kept away from buried lines.
