Pool Pump & Filter Replacement Cost in Sydney (2026)

By the WTD team · Updated November 2026

In Sydney a new pool pump runs $690–$1,375 installed (single-speed; $1,375–$2,525 variable-speed), a replacement filter $860–$1,725, and a salt chlorinator cell $460–$1,150. A variable-speed pump costs more upfront but uses far less electricity for the same water turnover, which wins the difference back over time.

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. A variable-speed pump costs more upfront ($1,375–$2,525 installed, against $690–$1,375 for single-speed) but runs slow and quiet most of the day, using far less electricity for the same water turnover. At our Sydney table's typicals the gap is $975 ($2,000 against $1,025), which the dearer pump wins back in power over time — how fast depends on your tariff and run hours.

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's mandatory Water Wise Guidelines. A full filter replacement lands in the $860–$1,725 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 is money poured 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.

Pump and cell together — our Sydney rows

Rows from our Sydney pool maintenance table. The pump row is supplied and installed, so there is no separate install line.

Catching worn equipment early is what a regular service is for — an annual equipment check ($170–$460) 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, $690–$1,375 for a single-speed pump (most around $1,025) and $1,375–$2,525 for variable-speed (most around $2,000). Single-speed pumps are the cheaper buy; variable-speed pumps cost more upfront but use far less electricity.

Is a variable-speed pool pump worth it?

In most cases yes. It runs slow and quiet most of the day and uses far less electricity than a single-speed pump, which wins back the price difference — about $975 at our Sydney table's typicals — over time; how fast depends on your tariff and run hours.

How much is a replacement pool filter in Sydney?

$860 to $1,725 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 is money into ageing gear, so replacing it — usually with an efficient variable-speed unit — is the better value.
