How to Fix a Leaking Shower Head
Figuring out how to fix a leaking shower head means first working out which part has actually failed. Water held in the head after a shower drains away on its own; water creeping past a tired seal in the wall mixer does not. Scarborough households can use the signs below to separate the two, and a licensed plumber takes the diagnosis from there.

A shower head leaking when off usually blames the mixer, not the head. Here is how to tell, what Queensland law lets you swap yourself, and when the job moves inside the wall.
Is a Dripping Shower Head Normal
A brief run of drips after you shut the water off is normal; a drip that goes on past those first moments is not. That comparison is the whole diagnosis.
Every head and arm holds a little water once the shower ends, and it empties out over the next minute or two. Nothing needs doing about that.
Once the drain-off finishes, a continuing drip means water is getting past a worn seal in the mixer behind the wall. Leave the head alone in that case, because the fault is not in it.
Signs Pointing to the Shower Mixer
A shower head drip comes from three spots: the join between head and arm, the mixer in the wall, or, where a bath and shower share one outlet, the spout with its diverter. Each one has its own tell:
Seepage at the head while you shower
That points to the arm join working loose or its seal giving up.
Drips after the water shuts off
The problem sits in the mixer: a worn washer or cartridge letting water slip past.
Crossed bath and shower flows
Bath water rising to the head, or shower water pouring from the spout, means the diverter or the spout itself is past its best.
Scale closing the spray holes
Build-up forces water out through other openings, which reads as a strange leak.
Inside the mixer, the cartridge sets both the flow and the hot-cold blend. Wear there can show up as a drip, a handle gone stiff, or water arriving at the wrong temperature.
The Shower Head Swap the Law Allows
Yes. The QBCC's unregulated list includes replacing a shower head, so no plumbing licence applies, provided the person doing it has the knowledge and skill the job calls for.
Neither QBCC approval nor council approval is needed beforehand, and no report follows the job. Licence or not, the result still has to satisfy the standards Queensland's plumbing law and codes set.
The mixer is where the rule ends. Repairing or replacing a fitting inside it counts as minor work, which needs a QBCC licensee though not a permit or extra paperwork.
A replacement head sold in Australia also needs registration under the Water Efficiency Labelling and Standards scheme, showing a star rating and water-use details wherever it is listed or advertised. Read that label before you buy, and let the rating decide.
Still Dripping After a Repair Attempt
When a new washer or cartridge still drips, the surface the part seals against is usually the problem. A washer closes onto the valve seat and a cartridge sits within the mixer body, so wear to either leaves the new part nothing to seal on.
A licensed plumber checks that wear and prices the repair. The figure depends on whether the head or the in-wall mixer is at fault, which part the mixer needs, and how easily the wall opens up.
Density does the rest of the damage in this suburb: the 2025 area-level estimate sits near 2,242 residents per square kilometre, so one upstairs drip becomes a neighbour's ceiling stain fast. For the mixer, the diverter and the arm, our shower repairs service covers the diagnosis and the licence side of the visit.
Dripping Shower Head Questions
Call (07) 3523 6484What makes a shower head drip?
Leftover water draining from the head after a shower stops by itself. A drip with the taps shut points to a worn washer or cartridge in the wall mixer, and a leak at the arm join shows only while the shower runs. Scale can block the spray holes, and a worn diverter on a bath spout can send water upwards.
Can I replace a shower head myself in Scarborough?
Yes. The QBCC treats swapping a shower head as unregulated work, open to anyone with the needed knowledge and skill, with no approval and no report. That work still must satisfy the standards the plumbing law sets, and anything inside the mixer stays with a licensed plumber.
Who fixes a dripping shower in a Scarborough rental?
Report it first. A Queensland tenant tells the property manager or owner as soon as possible, and the owner or manager keeps the home in good repair through the tenancy. Swapping a head is among the few tiny jobs a rental allows without a licensee; mixer repairs are not.
What should the label on a new shower head show?
Star ratings and water-efficiency figures. A head sold in or into Australia needs registration under the Water Efficiency Labelling and Standards scheme and those details displayed anywhere it is advertised, online included. The label tells the efficiency story, so compare ratings rather than brands.
