How to Fix a Leaking Shower Head
A dripping shower head comes down to one question: leftover water, or a real leak? A little stored water always empties out for a minute or two after you shut the tap. A drip that carries on well past that means a seal has failed inside the mixer, and that is where working out how to fix a leaking shower head begins.

Homes in Ferny Hills span the 1960s subdivisions through to recent builds near the shops by Ferny Grove station, just across the boundary, so bathroom fittings here run from original to brand new. A licensed plumber reads the drip fast: the fitting on the wall, or the mixer tucked inside it.
What Leftover Water Looks Like
Water resting in the head empties out for a short stretch once the tap closes, and that is normal shower behaviour. Give the head a shake, wait a minute, and the last of it dries up on its own.
Anything longer is a different problem. If water keeps coming while the taps are firmly off, the mixer concealed in the wall is at fault. A tired washer or cartridge in there is letting supply creep past its sealing face.
That tells you two things straight away. A replacement head will not cure it. And the repair sits on the licensed side of the fence, which the next section sets out.
The Shower Head Swap the Law Allows
Yes, the Queensland Building and Construction Commission treats a head swap as unregulated work, so no plumbing licence applies and any householder with the competence for it can do the job.
- Neither the QBCC nor council needs to approve it.
- There is nothing to report once the new head is on.
- Licence or not, the finished job has to satisfy the standards Queensland's plumbing law and codes set.
- A head sold in or to Australia also needs registration under the Water Efficiency Labelling and Standards (WELS) scheme, with its stars shown wherever it is advertised, online included.
The line stops at the wall. A cartridge or valve within the mixer is work for a licensed plumber, because the unregulated list names the head alone.
Visible fitting: yours. Parts inside the tiling: ours.
A Queensland rental works the same way, with one duty attached. Swapping a head is one of the very minor jobs open to unlicensed hands on a rental, while Queensland tenancy law puts the repair on the owner or manager, who keeps the home sound across the tenancy. Tenants report problems to the manager or owner as soon as they appear.
Signs Pointing to the Shower Mixer
A drip can start in three places. First, the collar where the head attaches to its arm; second, the mixer behind your tiles; third, on a shower over a bath, the spout and the switch that routes water upward. Each one shows a different sign:
The arm connection
Seepage there only while the shower runs means the joint has loosened or its O-ring has failed.
The mixer
A drip with the taps off is its signature. The cartridge also governs the hot-and-cold blend, so a leaking mixer often brings a dragging lever or water that never reaches the temperature you set.
The bath spout
Water reaching the head while the tub fills, or spilling from the spout mid-shower, means a worn diverter rather than anything on the wall.
Scale
Crust blocking the spray channels pushes water sideways through other openings, which looks like a fault but is really a blockage.
Reading the pattern first saves a wasted purchase. It tells you which part owns the drip before any money changes hands.
Worn Seats and Bodies Behind the Wall
A drip that survives fresh parts usually means the metal around them is the problem. A washer closes down onto the valve seat, and the cartridge shuts off within the body of the mixer, so a scored or eroded surface leaves the new part nothing to close against.
Skip the trial-and-error. That assessment belongs to a licensed plumber, who opens the mixer, inspects the surfaces and names the repair. Work on a fitting within the mixer is classed as minor work, which a QBCC licensee may do without a permit or any compliance paperwork.
Three things then move the price: whether the fault is the fitting or the wall, which part the repair takes, and how much tiling has to come apart to reach the mixer. Every figure lands in a fixed quote before any work starts.
When a Plumber Should Take Over
Hand the job over as soon as the signs point past the head. A dragging lever, water that misses its set temperature, or damp spreading beyond the recess all point at the mixer, and water escaping a shower damages far more than the bathroom.
Our shower repairs service covers the mixer, the diverter, the arm and low-flow faults, and every job is done by a licensed plumber.
Ferny Hills Shower Questions
Call (07) 3523 6484Why does my shower head drip in Ferny Hills after I turn it off?
Leftover water drains from the head and the pipe above it for a minute or two after use, which is normal. A drip past that window is the mixer. A tired washer or cartridge inside it is letting water creep past the seal.
What causes a shower head to leak?
Four culprits. A loose or failed seal at the arm connection, weeping only mid-shower. A worn cartridge in the mixer, dripping with the taps shut. Crusted scale narrowing the spray channels. On a bath-shower, a diverter sending water the wrong way.
My shower still drips after a new cartridge. Why?
The seat or the body may be scored. A washer closes onto the valve seat and the cartridge shuts inside the mixer body, so damaged metal leaves the fresh part nothing to seal against. A licensed plumber inspects the mixer and quotes; no second part will help.
Who fixes a dripping shower head in a Ferny Hills rental?
Tenants report the drip to the property manager or owner straight away. Queensland tenancy law then puts the repair on the owner or manager, who keeps the home sound through the whole tenancy. Swapping a head is one of the very minor jobs that need no licence here.
