Almost every leaking tap comes down to a worn internal part, a damaged sealing surface, or too much pressure behind it. Knowing which one you are dealing with is what tells you whether it is a five-minute washer change or a job for a plumber. Here is what is usually going on.
On traditional taps, a rubber washer presses down onto a metal seat every time you turn the tap off. Over years of use, that rubber hardens, splits and wears until it no longer seals, and the tap drips from the spout. This is the single most common cause of a dripping tap, and on a standard tap it is also the cheapest to fix.
O-rings seal the moving parts of the tap so water does not escape around the handle or the base. When they dry out and perish, you get a leak that appears around the top or base of the tap rather than from the spout. Replacing the O-rings and seals resolves that particular leak.
Modern single-lever mixer taps do not use a washer at all. Instead, two ceramic discs slide across each other to control flow and temperature. When that cartridge wears, the mixer drips, becomes stiff or hard to position, or weeps at the base. The fix is a new cartridge rather than a washer, which is why identifying your tap type matters (more on that below).
The seat is the surface the washer closes against. If it becomes corroded, pitted or scored - often from a worn washer being left too long - a brand-new washer still will not seal against it, and the tap keeps dripping. The fix here is reseating: machining the surface smooth again with a reseating tool. This is the step where most do-it-yourself repairs come unstuck.
Mains pressure runs high in a lot of Sydney suburbs. Excess pressure hammers washers and cartridges and wears them out far faster than normal, so taps that were repaired recently start dripping again. If leaks keep recurring across several taps in the house, the underlying cause is often pressure, and a pressure-limiting valve is the proper long-term fix rather than repeated washer changes.
Minerals in the water and years of daily use gradually corrode internal components and, eventually, the tap body itself. Once the body is corroded or the fittings are seized, repair stops being worthwhile, and replacement becomes the sensible option. A tap over about 10 to 15 years old that has started leaking is often at this point.
Some leaks are obvious. Others hide under the sink or behind an appliance until they have already done damage. Watch for:
If you've noticed any of these warning signs, your tap may have an underlying issue that needs attention. Getting it checked early can help prevent leaks, water damage and more costly repairs.

A steadily dripping tap can waste thousands of litres of water a year - water you are paying for, quarter after quarter, that goes straight down the drain. If the leak is on the hot side, you are also paying to heat it.
There is damage to think about too. Water pooling around the base of a tap or seeping under the sink slowly swells cabinetry, lifts benchtops, marks tiles and can lead to mould.
A drip is also a symptom: the same worn part that lets a little water past today tends to fail later, usually at an inconvenient moment. Dealing with it early is almost always cheaper and less disruptive than waiting.
Plenty of drips are beyond a straightforward washer change, and trying to force those usually costs more in the end. It is worth calling a licensed plumber when:

If you have a simple, accessible washer tap dripping from the spout, this is a reasonable job to try yourself. If it is a mixer, a leak inside the wall, or a tap you cannot isolate, skip to the next section - that is genuinely plumber territory.

Identifying the tap type first is essential: match the fix to the mechanism, and the leak stops; guess wrong, and it keeps dripping. If the drip continues after a new washer, the seat itself is likely damaged and needs reseating, which is where a licensed plumber's tools make the difference.
No - and this is the most common mistake. Only traditional compression taps use a washer. Single-lever mixer taps use a ceramic cartridge, so fitting a washer will not help and can make the leak worse. Identifying the tap type first is essential: match the fix to the mechanism, and the leak stops; guess wrong, and it keeps dripping.
It depends on the tap type, the part required, and how accessible the tap is - a washer or O-ring is a small job, while a cartridge or a full tap replacement costs more. Because we charge a $0 call-out fee and give a fixed price before starting, you know the cost before any work happens, with nothing added afterwards. If you have several taps leaking, doing them in one visit is more economical than separate call-outs.
Almost always. A steady drip can waste thousands of litres a year and quietly damage cabinets, benchtops and tiles - and if it is the hot tap, you are paying to heat wasted water. The repair is usually inexpensive relative to the water and damage it prevents. Fixing it early also keeps the job small, before a worn washer scores the seat and turns a simple repair into a larger one.
If it is a straightforward washer tap dripping from the spout and you can isolate the water, changing the washer is a reasonable DIY job. Turn the water off first, match the replacement part, and do not over-tighten on reassembly. Call a plumber if the drip returns after a new washer, if it is a mixer tap, if the leak is at the base or in the wall, or if you cannot isolate the water safely.
Usually because the valve seat is damaged, the wrong washer was fitted, or high water pressure is wearing parts out quickly. A new washer cannot seal against a scored seat. A plumber can reseat the tap and test your water pressure so the repair actually lasts, rather than dripping again within weeks.
Generally, the landlord or agent, as tap washers and minor leaks fall under maintaining the property - but check your tenancy agreement and report the leak promptly. Sydney Water is only responsible for leaks on their side of the water meter, not your taps or internal pipework.
In most cases, the same day, and usually in a single visit, because we carry common washers, O-rings and cartridges on the van. More complex jobs or full tap replacements can take a little longer, which we confirm after assessing the tap.
