THE SHORT ANSWER

In short

Stop turning the handle: forcing it can snap the spindle and make it worse. Close the small isolation valve under the sink or basin, or if there isn’t one, the meter tap. Then call us on 0420 102 394. A tap broken so that a lot of water is being wasted is an urgent repair in a rental.

DO THIS FIRST

Do this first

1

Stop forcing it

Leave the handle alone.

2

Close the isolation valve

Under the sink or basin, on the hot or cold pipe: clockwise until it stops.

3

Or the meter tap

If there is no valve, or water still runs. Find your water meter

Where this advice comes from

WHAT IS HAPPENING

What is going on inside the tap

Every tap has a part inside that closes the waterway. Older two-handle taps use a rubber washer on a jumper valve, pressed down onto a brass seat as you turn the handle. Most newer taps and mixers use a ceramic disc cartridge: two polished discs that slide over each other to open and close. A tap that won’t turn off has usually lost that seal.

In a washer tap, the washer wears, hardens or splits, or the seat under it becomes pitted, so turning harder achieves less and less. Eventually the thread on the spindle strips and the handle spins without closing anything. In a mixer, grit or scale scratches the ceramic discs or the cartridge cracks, and the lever goes loose or water runs in every position.

Sydney Water says a slowly dripping tap can waste a few litres an hour, and a constantly running toilet thousands of litres a day (Sydney Water). A tap stuck fully open wastes far more, and if it is the hot tap you are paying to heat that water too.

DO NOT

Don’t make it worse

  • Don’t use pliers on the handle
  • Don’t leave it running overnight
  • Don’t take the tap apart with the water on
  • Don’t keep cranking a washer tap tighter: it crushes the washer and strips the spindle, turning a small repair into a new tap
  • Don’t prise the cap or lever off a mixer to look inside while the water is still on

WHY IT HAPPENED

Why taps fail

Tap repairs are among our most common jobs: 2,542 since 2019. Where our plumbers recorded a cause, the most common were: worn tap washer or cartridge (307 jobs), water leak (289 jobs), burst water pipe (49 jobs).

Likely causeTell-tale signsThe usual fix
Worn washer or jumper valveAn older two-handle tap that drips for weeks, then won’t shutA new washer and jumper, and the seat refaced if it is pitted
Stripped spindleThe handle spins freelyNew spindle or tap body parts
Damaged ceramic cartridgeA mixer lever that is loose, or water in every positionA new cartridge to suit the brand
Grit after mains workStarts straight after a water outage or works in the streetClean or replace the cartridge, and flush the line
Old or corroded tap bodyLeaks from the body or base, green depositsA new tap; we also fit customer-supplied WaterMark taps

WHEN WE ARRIVE

What we do when we get there

1

Isolate

Water off at the valve or meter so we can work safely.

2

Identify the tap

Washer, cartridge or the whole tap: we tell you which, and whether the part is on the van.

3

Fixed price

You approve the price before we start.

4

Repair

A new washer, cartridge or tap, with the seat checked so it seals properly.

5

Valves where missing

If the sink had no isolation valves, we can fit them, so next time you can turn off just that tap.

WHAT IT COSTS

What a tap repair costs

Half of our 2,303 priced tap repair jobs since 2019 cost between $330 and $946, including GST, with a median of $495.

A washer or cartridge usually sits toward the lower end; a new tap or mixer, or a shower mixer behind tiles, toward the upper end.

$0 call-out Monday to Friday, 7:00am to 5:00pm. After hours a call-out fee of $199 to $399 applies, confirmed by text before we dispatch.

WHO IS RESPONSIBLE

Who is responsible?

In a rental, a fitting broken so that a substantial amount of water is being wasted is an urgent repair; a slow drip is a normal repair, but report it anyway (tenants: what to do). Landlords can only pass water usage charges to tenants on a water efficient property, which includes having no leaking taps (NSW Government), so a quick fix suits everyone.

In strata, taps belong to the lot they serve, so the owner of that lot pays (strata: who pays).

INSURANCE

Taps, water bills and insurance

Insurers don’t pay for a worn tap: that is maintenance. If a tap was left running and a sink overflowed, the water damage may be covered, so ask.

A big bill from a running tap won’t qualify for Sydney Water’s hidden leak allowance, which excludes visible leaks such as taps (Sydney Water).

NEXT TIME

Prevent it next time

  • Fix dripping taps early: worn washers and cartridges get worse
  • Know where your isolation valves are
  • Label them
  • After mains work in your street, run a tap for a minute before using mixers, to flush out grit
  • Close taps firmly but gently: forcing a washer tap shut wears it out faster
