Pool Pump & Filter Replacement Cost in Sydney (2026)

By the WTD team · Updated June 2026

In Sydney a new pool pump runs $575-$1,725 installed, a replacement filter $345-$920, and a salt chlorinator cell $460-$1,150. A variable-speed pump costs more upfront but cuts running costs by 50-70%, so it usually pays for itself before the warranty is up.

Quick answer — equipment replacement in Sydney

Pump — where single-speed vs variable-speed really matters

A single-speed pump is cheapest to buy but runs flat-out whenever it's on, and a pool pump is typically 30% of a pool's power bill. A variable-speed pump costs more upfront (top of that $575–$1,725 band) but runs slow and quiet most of the day, cutting pump electricity by 50–70%. On a Sydney pool running through summer that's commonly $400–$600 a year back in your pocket, so the dearer pump usually pays for itself well inside its warranty.

NSW efficiency rules

Many single-speed pumps no longer meet current pool-pump energy standards, so when an old one dies you're often replacing it with a multi- or variable-speed unit anyway — worth knowing before you're quoted "like for like".

Filter — sand, cartridge or glass media

Cartridge filters are the most common on Sydney backyard pools and the cheapest to replace, but the cartridges themselves wear out and need swapping every few years. Sand filters are cheap to run but use more water backwashing. Glass-media filters cost a little more but filter finer and use less water — a real consideration under Sydney water restrictions. A full filter replacement lands in the $345–$920 band depending on type and size.

Repair or replace?

A pump motor or filter housing is often worth repairing if the unit is under about seven years old and parts are available. Past that, a reseal or motor rebuild can cost more than half a new pump, and you're pouring money into ageing gear — replacement is usually the call. A salt chlorinator cell is a consumable: it loses output over five to seven years and is replaced, not repaired.

Worked example — pump + cell, Northern Beaches

Catching worn equipment early is what a regular service is for — an annual equipment check ($230–$575) usually flags a failing pump before it strands you with a green pool in January.

Frequently asked questions

How much does a new pool pump cost in Sydney?

Installed, $575 to $1,725 depending on size and type, with most around $1,025. Single-speed pumps sit at the bottom of the range; variable-speed pumps cost more upfront but cut running costs by 50-70%.

Is a variable-speed pool pump worth it?

In most cases yes. It runs slow and quiet most of the day and cuts pump electricity by 50-70% — commonly $400-$600 a year on a Sydney pool — so it usually pays back the price difference inside its warranty.

How much is a replacement pool filter in Sydney?

$345 to $920 installed, depending on whether it's a sand, cartridge or glass-media filter and the size of the pool. Glass-media filters cost a little more but use less backwash water.

How often does a salt chlorinator cell need replacing?

Every five to seven years. A cell is a consumable that slowly loses output, so it's replaced rather than repaired — budget $460 to $1,150 installed.

Should I repair or replace a failing pool pump?

If the pump is under about seven years old and parts are available, a repair can make sense. Past that, a rebuild often costs more than half a new pump, so replacing it — usually with an efficient variable-speed unit — is the better value.
