How to Fix a Leaking Shower Head
Not every dripping shower head needs a plumber. Some drips are just the last of the water emptying out of the fitting; others mean a seal has failed somewhere it shouldn't. How to fix a leaking shower head depends on which of the two you have, and the difference is easy to spot once you know what to watch for.

We sort these jobs for Murrumba Downs households all year. The diagnosis matters more than the repair, because the cause decides who is legally allowed to do the work. Queensland draws a firm line at the wall.
Normal Drips Versus a Failing Seal
Water left in the fitting after a shower drains away on its own, but a drip that continues with the taps shut means a seal in the mixer has failed. Gravity empties the head and the pipe above it over a minute or two once you turn the shower off. That brief trickle is nothing to worry about.
A failed seal behaves differently. The washer or cartridge inside the mixer is supposed to shut the supply off completely; when one perishes, water creeps past and exits at the lowest point, usually the head. The head itself is often innocent.
Census figures put separate houses at about three quarters of the suburb's homes, so most of these mixers serve family bathrooms run hard morning and night. A seal holding mains pressure around the clock wears out no matter how good the fitting was.
Signs Pointing to the Shower Mixer
A drip has three possible sources: the joint where the head attaches to the arm, the mixer concealed in the wall, and on a bath-shower combination, the spout and its diverter. Each has its own tell.
The joint at the arm
Water appearing there only while the shower runs means the connection has come loose or its washer has perished. Dry with the water off, wet with it on.
The mixer
A drip that persists with the taps closed comes from inside the wall, where an ageing washer or cartridge lets supply slip through. A stiff handle or water at the wrong temperature points the same way.
The bath diverter
The head feeding water while the bath tap runs, or the spout spilling mid-shower, blames the diverter or a restricted spout rather than the head.
Scale matters as well. Mineral crust blocks the spray holes and pushes water out through gaps elsewhere in the head, which reads as an odd leak but is really a blockage. The suburb's reticulated supply feeds every street the same, from the blocks near the Unitywater wastewater treatment plant to the newest estates, so nobody is spared the build-up.
The repair side is separate work. Shower repairs covers the mixer, the diverter and the licensing rules around them.
Still Dripping After a Repair Attempt
When a new washer or a new cartridge fails to stop the drip, the brass seat or the mixer's own body is usually worn. A washer closes against the seat, and a cartridge closes inside the body. Damage either surface and the new part has nothing to seal on, so the leak continues.
A licensed plumber assesses that. Queensland treats the repair as minor work needing a QBCC licensee, with no permit and no paperwork filed afterwards. Buying a second part on spec just spends money on the wrong suspect.
The Shower Head Swap the Law Allows
Yes, you may swap the shower head yourself. The QBCC lists that job as unregulated work, a task any capable person may take on. No approval from the QBCC or City of Moreton Bay applies, and nothing is reported afterwards.
Licensed or not, the work still has to comply with the minimum standards in the plumbing codes. Two limits apply:
The mixer stays licensed
A cartridge or valve inside that unit is a job for a licensed plumber, because the unregulated list covers the head and stops there.
Rentals are tighter
Queensland allows an unlicensed hand to change a shower head on a rental, among the few jobs open to one. The owner or manager has to keep the premises in repair throughout the tenancy, and a tenant has to report damage or needed repairs promptly.
One shopping note before you buy. A shower head sold in or to Australia has to be registered under the national water rating scheme (WELS) and show its stars and water-use numbers on every listing and ad, online included. Check the label wherever you shop.
When to Ring Us Rather Than Guess
Ring a plumber when the drip continues with the water off, or when a new part has not stopped it. Water turning up anywhere the shower should not put it counts as well. Those signs put the fault in the wall, and that work needs a licence.
The price depends on where the fault sits: the head, the mixer or the diverter. The part required and how easily the wall unit can be reached also count. A fixed quote settles it before any work starts.
Dripping Shower Questions From Murrumba Downs
Call (07) 3524 7163What makes a shower head drip in Murrumba Downs?
One of four faults, usually. Seepage at the arm joint means a loose connection or a perished washer there, while a drip with the taps off points to the mixer's washer or cartridge. Scale can plug the spray holes, and a worn diverter on a bath-shower set sends water the wrong way.
Do I need approval to change a shower head in Queensland?
No. The swap is unregulated work, so neither the QBCC nor City of Moreton Bay signs off beforehand and no report goes in afterwards. The finished job still has to comply with those same standards.
Why does my shower leak where the head joins the arm?
Water showing at that join while the shower runs means the joint has slackened or its washer has perished. Swapping the head is the job you may do yourself, since Queensland treats it as unregulated work.
What should a replacement shower head have on it?
A water rating label. Every shower head offered for sale in Australia has to be WELS-registered and display its star rating and consumption figures wherever it is sold or advertised, online included. Shops near Murrumba Downs stock labelled models.
