Drip. Drip. Drip. A leaking tap is one of the smallest faults a house can have and one of the most maddening, and it is also quietly expensive, because a steady drip wastes thousands of litres a year and a dribbling hot tap is pouring heated water, and the energy that made it hot, straight down the drain. The good news is that tap repair sits in the small territory of plumbing work a WA homeowner can legally do themselves, and done with a little care it is a genuinely satisfying fix. Here is how to do it properly, and how to know when the drip is a symptom of something bigger.
First, understand why taps drip
Almost every dripping tap comes down to a worn sealing surface. In traditional two handle taps, a rubber washer presses onto a brass seat to close the flow, and time, use and Perth’s mineral rich water harden the washer and score the seat until they no longer seal. In quarter turn and mixer taps, the sealing happens inside a cartridge or between ceramic discs, and grit or scale scratching those surfaces produces the same result. Leaks from the spout point to the sealing surfaces. Leaks from around the handle or the base of a mixer point to O rings and body seals instead. Knowing which leak you have tells you which parts to buy before anything comes apart.
The repair, step by step
Start by isolating the water, at the isolation valve under the fixture if one exists and works, otherwise at the mains, then open the tap fully to drain the line. Put the plug in the drain, because tap screws have an magnetic attraction to plugholes. For a traditional tap, prise off the handle button, remove the handle screw and handle, unscrew the headgear with a spanner, and lift out the spindle to reveal the washer at its base. Replace the washer, and inspect the brass seat below with a fingertip, if it feels rough or scored, a new washer will seal poorly and briefly, and the seat needs reseating with an inexpensive reseating tool or a professional’s attention. While everything is apart, replace the O rings on the spindle and smear the threads with tap lubricant, which transforms how the tap feels for years. Reassemble snugly without gorilla force, restore the water slowly, and test. For mixers and quarter turn taps the logic is identical with different parts, isolate, remove the handle, extract the cartridge, and replace it with the matching unit, and matching is the operative word, because cartridges are rarely interchangeable between brands, so take the old one, and ideally the brand name, to the supplier.
The Perth complication
Our hard water gives tap repairs a local flavour. Scale builds on seats, spindle threads and cartridge surfaces, which is why Perth taps drip earlier and why repairs done without cleaning the mating surfaces fail sooner. Before fitting any new washer or cartridge, clean the seat and surrounds, a vinegar soaked cloth and a few minutes dissolve the mineral crust, and the new seal beds onto clean metal instead of grit. It is a thirty second habit that roughly doubles how long the repair lasts, and it applies to every rubber and brass interface in the house.
When the drip is a messenger
Some leaks are not really about the tap. If a freshly repaired tap starts dripping again within weeks, if multiple taps around the house have begun leaking in the same season, or if taps hammer, shudder or shriek when closing, the underlying issue is often water pressure running too high, which batters washers and seals throughout the system and shortens the life of every repair. That pattern deserves a pressure test and, where needed, a pressure limiting valve, because fixing the cause costs less than repeatedly fixing its victims. Similarly, a tap that will not stop dripping no matter what parts go in usually has a damaged seat or body, and knowing when to replace the tapware rather than nursing it is part of the skill.
Where the DIY road ends
Washers, O rings and cartridges are legitimate homeowner territory in WA. Replacing the tapware itself, working on anything connected by flexi hoses behind walls, repairs at the breech or in wall bodies, and anything that involves altering pipework are licensed work, legally and for good reason, since a mistake there leaks inside a wall rather than into a sink. The same applies if your isolation valves are seized and the repair cannot be safely isolated, which is itself a fault worth fixing while someone licensed is on site.
Silence, restored
A tap repair done properly, clean seat, quality washer or matched cartridge, lubricated threads, gentle reassembly, buys years of silence for the price of parts and half an hour. If your tap has beaten the standard repair, if the drips are multiplying across the house, or if you would simply rather it handled by someone who does this daily, Drains Plus fixes taps across Perth alongside our drainage work, and every job comes with our free plumbing health check, which is often where we catch the seized valve or high pressure that was planning your next drip. Call us and make the sound stop for good.
