How to Fix a Leaking Shower Head
A dripping shower head has one of two explanations: leftover water finding its way out after use, or a seal inside the mixer that has finally worn through. The head is rarely the culprit for an ongoing drip, so knowing how to fix a leaking shower head starts with that first judgement. Our Clontarf team gets these calls every week, and a licensed plumber sorts the diagnosis in minutes.

At the last census the suburb counted 3401 homes and a median age of 46. The postwar houses near the Hornibrook Bus Lines depot have kept their first bathrooms, mixers and all, and those seals are well past their prime.
Normal Drips Versus a Failing Seal
Leftover water finishing its drain is normal; a shower still dripping once the taps are shut points to a worn seal in the mixer.
Every shower leaves water sitting in the head and the arm, and it runs out over the next minute or so. That is expected, and it stops on its own.
Timing separates the two. Residual water finishes fast and leaves nothing behind. A worn seal keeps dripping at a steady rate, hour after hour, long after the shower is off.
The mixer is where that second drip starts. A tired washer or a spent cartridge lets water creep past the sealing faces, and the spray face is the lowest exit, so the head cops the blame.
Signs Pointing to the Shower Mixer
A dripping shower traces to three places: the join where the head screws onto the arm, the mixer behind the wall, and, on a bath-shower set-up, the spout and diverter.
Each spot has its own tell:
The head-to-arm join
water escaping at that spot while the shower runs means the fitting is loose or the washer inside it has had it.
The mixer
a drip arriving with everything shut off points at the washer or cartridge within. The cartridge sets the flow and the hot-cold blend, so a tired one can also show up as a stiff handle or odd temperatures.
A bath-shower combo
the head letting water through while the bath spout is running, or the spout running during a shower, signals a tired diverter or a partly blocked spout.
Mineral scale is the fourth suspect. Build-up can plug the spray holes and force water out through other openings, which reads like a leak but is really the head misbehaving.
Worn Seats and Bodies Behind the Wall
When a fresh washer or new cartridge fails to stop the drip, the valve seat or the mixer body is usually at fault. A licensed plumber is the one to assess that.
The reason is geometry. A washer closes against the seat, and a cartridge seals within the body of the mixer. Score or pit either surface and the new part cannot close clean, so the drip continues.
Repairing or replacing a fitting within the mixer is minor work in Queensland. A QBCC licensee carries it out, with no permit and no Form 4. Plenty of postwar bathrooms here hide a scored seat rather than a spent part.
What Counts as Unregulated Plumbing Work
Yes, the QBCC treats a shower head swap as unregulated work, so anybody who holds the knowledge and the skill for it may do the job.
In Queensland that means no licence, and neither the QBCC nor your council needs to approve it or receive a report. The finished job is still held to the minimum standard set out in the plumbing laws and codes.
The line stops at the mixer. The QBCC's list of unregulated jobs covers the head and nothing further, so work on the mixer or its cartridge belongs to a licensed plumber.
Rentals are stricter still. A head swap is one of the very few jobs a Queensland rental leaves open, while the owner or manager has to keep the place in sound repair through the tenancy. Tenants report damage or needed repairs to the manager as soon as they can.
Buying a replacement head? WELS rules apply. Any head sold in Australia carries WELS registration, with the star rating and water-use figures shown wherever the product is advertised, online included.
When to Ring a Plumber About the Drip
Ring (07) 3523 7121 when the drip continues with everything shut, when a fresh part has failed to stop it, or when the wall beside the mixer reads damp. Those are mixer faults, and the mixer is licensed work.
The price of the fix turns on whether the fault sits in the head or behind the wall, the part required, and how easily we reach the mixer. You see a fixed quote before any work starts. For stiff handles, worn seats and water escaping the stall, our shower repairs page covers the work.
Shower Drip Questions From Clontarf
Call (07) 3523 7121Why is my shower head dripping after I turn it off?
Water held in the head and arm drains out briefly after use, and that is normal. A drip that keeps arriving once everything is shut off comes from the mixer, where a tired washer or spent cartridge lets water slip past, not from the head at all.
Can I replace a shower head myself in Clontarf?
Yes, provided you have the knowledge and skill for it. Queensland treats the swap as work anyone may do: no licence, no sign-off from the QBCC or council, and nothing to report. The finished job is still held to the minimum standard.
What makes water leak where the head joins the arm?
Drips at that join during a shower usually mean the fitting has worked loose or its washer has had it. Swapping the head is the one job the QBCC leaves open; the arm and the mixer behind it are not.
What rating does a new shower head need in Clontarf?
Look for the stars. WELS rules require a head sold in Australia to carry registration and show its rating and water-use figures in every listing, online ones included.
