You should expect written warranty terms covering defects caused by the plumber’s workmanship. The period varies by plumber and type of work. This contractual warranty is separate from any manufacturer’s product warranty and your statutory rights under Australian Consumer Law and, where applicable, NSW legislation.
What should a workmanship warranty cover?
A plumber’s workmanship warranty should cover faults caused by the way the installation or repair was completed. For example, an incorrectly made connection may be a workmanship defect, while an internal fault in a new tap may fall under the manufacturer’s warranty.
Product warranties can cover fixtures, appliances, parts and materials. Check whether the plumber will manage a product claim and whether diagnosis, removal, call-out labour, replacement and reinstallation are included. A manufacturer may provide a replacement product without covering these associated labour costs, subject to the written terms and your statutory rights.
Possible contractual exclusions include normal wear, misuse, inadequate maintenance, damage by others and unauthorised alterations. Exclusions must be clearly stated and cannot remove rights that cannot legally be excluded.
How long can coverage last?
There is no standard plumbing warranty period. Contractual coverage depends on the plumber’s terms and the type and scope of work, while products may have separate warranty periods. Check both the duration and whether coverage starts from purchase, installation, completion or invoicing.
Under Australian Consumer Law, covered plumbing services must be provided with due care and skill, be fit for a purpose you made known, and be supplied within a reasonable time if no timeframe was agreed. These consumer guarantees operate independently of a business warranty, so statutory rights do not necessarily end when a written warranty expires.
Some residential plumbing work may also be covered by statutory warranties under the NSW Home Building Act 1989. Eligibility, warranty periods and claim time limits depend on the work and circumstances; confirm the current position with NSW Fair Trading.
What should I get in writing?
Before approving the work, confirm:
- when the workmanship warranty starts and ends
- the work, labour, call-outs and replacement parts covered
- exclusions and required maintenance
- applicable manufacturer warranties
- who handles product claims and associated labour
- how and when faults must be reported
- the remedies available for defective work.
Keep the scope of work, invoice, proof of payment, product details, warranty documents and maintenance records.
Before hiring, verify the licence, written scope, insurance and how defects will be handled. Contact our licensed Sydney plumbing team if you want warranty terms and repair scope set out in writing before work begins.
