New Plumbing Installation vs Repair

 

Cost Breakdown: New Plumbing Installation vs Repair — Which Is More Economical in Mandurah?

When faced with a plumbing problem, homeowners in Mandurah often ask whether it’s smarter to repair the existing system or invest in new installation. At Aquasonic Plumbing & Gas, we’ve seen both sides, and the choice usually comes down to cost, efficiency, and long-term value.

When Repair is Better Value

• Minor leaks & drips: Replacing washers, seals, or a short section of pipe is far cheaper than installing new.

• Blockages: Clearing drains with jetting or rodding is usually more economical than replacing entire lines.

• Hot water units under 8 years old: Repairs or part replacements (valves, thermostats, or elements) often restore full performance.

When Installing New is Wiser

• Frequent breakdowns: If repairs are ongoing, replacement avoids constant call-out costs.

• Old hot water systems (10+ years): Newer units are more energy-efficient, saving you money on bills.

• Corroded or outdated piping: Replacing old galvanised or rusted pipes reduces leak risks and improves water quality.

• Compliance upgrades: Sometimes regulations require new installations to meet WA standards.

Long-Term Cost Considerations

• Water bills: Old or leaking systems waste water and money.

• Energy efficiency: New systems, especially solar or heat pump hot water, reduce ongoing energy costs.

• Maintenance frequency: New installations require less upkeep and fewer emergency call-outs.

• Property value: Updated plumbing boosts home value and market appeal.
