Plain-English plumbing help for Sydney homes

Burst pipes, slow drains, cold showers and the awkward question of who to call. This guide explains what is going on, what is safe to do yourself, and when the job belongs to a licensed plumber.

Find your part of Sydney

Sydney is a patchwork of housing eras. A Federation cottage in the inner west, a beachside apartment block in the east and a recent estate in the north-west all fail in different ways, and the guides here are written with that in mind.

Pick a region on the map for a general picture of its housing and common plumbing considerations, then follow the links to individual suburb guides. The full list sits on the Sydney areas page.

What this site is, and is not

Graham & Sons Plumbing is an information resource. It is a guide to residential plumbing in Sydney: the services people ask about, the suburbs they live in, and the practical decisions in between.

It is not a plumbing business. We do not take bookings, give quotes or dispatch anyone to your home, and there is no way to contact a tradesperson through these pages. Read the full explanation on the about page.

When a job needs a licensed plumber, the guides say so plainly and explain how to check a licence through the NSW Fair Trading licence check. They do not recommend any particular company.
