In a nutshell
- 🔧 A simple quarter-turn of the tap’s packing nut can stop many handle leaks fast—use a cloth and snug spanner, tighten 1/8–1/4 turn, and avoid overtightening.
- 🕵️ Diagnose before buying parts: spout drip = worn washer or ceramic cartridge; handle weep = loose packing nut; spray/low flow = clogged aerator.
- 💷 Small drips, real money: ~11–15 litres/day (1 drop/sec) wastes 4–5.5 m³/year, costing roughly £10–£18, with average UK bills around £473 (Ofwat).
- ⚖️ Pros vs. Cons: Pros—immediate, no parts, low risk; Cons—may be temporary for spout drips, overtightening risk, not universal on designer taps.
- 🧰 Practical plan: shut the isolation valve if needed, tighten and test, monitor for a week; if the drip returns, replace the washer/cartridge and keep PTFE tape, spare washers, and a spanner handy.
Every drip carries a cost. In homes across the UK, that familiar tick-tick of a leaky faucet (tap) adds up to wasted litres, inflated bills, and needless carbon tied to water treatment. The good news is that the remedy is often wonderfully simple. In many cases, a swift, careful quarter-turn can silence the drip and trim your costs before you even reach for replacement parts. I’ve tested it in my own flat and on reader call-outs: a quick adjustment can buy you months of peace and protect your wallet. Small actions compound into big savings—and this is one of the smallest, smartest actions you can make today.
The Simple Twist: Tighten the Packing Nut
On traditional UK pillar or mixer taps, a small hex nut just beneath the handle—known as the packing nut or gland nut—compresses the stem’s packing or O-ring. If the handle area weeps or the tap refuses to shut off crisply, a gentle quarter-turn clockwise can restore a watertight seal. It’s the fastest legitimate fix for many nuisance drips, and it doesn’t require dismantling the tap body. Place a soft cloth over the nut to protect the chrome, brace the tap to avoid stressing the pipework, and use a snug spanner to avoid rounding the flats.
Here’s a quick sequence I use on assignments around London and the South East:
- Turn off the isolation valve (quarter-turn slot-head under the sink) if the drip is heavy; for light weeps, you can often adjust live with care.
- Hold the tap body steady; tighten the packing/gland nut by roughly 1/8–1/4 turn.
- Test the handle: it should feel firm, not stiff; back off slightly if it binds.
- Open and close the tap several times to check for drips.
Do not overtighten. Too much force can crush washers or crack ceramic internals in modern taps. If tightening only helps for a day or two, that’s a sign you’ll need a new washer (compression taps) or ceramic cartridge (quarter-turn taps). But as a triage move—late at night, ten minutes before guests arrive—the twist is a budget-saver.
Diagnosing the Drip: Washer, Cartridge, or Aerator?
Before you reach for parts, pinpoint the source. A drip from the spout after shut-off often means a worn washer (older compression taps) or a tired ceramic cartridge (modern quarter-turn taps). Moisture around the handle suggests packing that needs the tightening trick. A scattered spray or weak flow points to a clogged aerator—which simply unscrews for cleaning. Correct diagnosis saves time, parts, and frustration.
Use this quick reference I share with readers who want results in under an hour:
| Symptom | Likely Cause | Simple Twist | Notes |
|---|---|---|---|
| Drip from handle/spindle | Loose packing nut | Quarter-turn packing nut | Works on many compression taps |
| Drip from spout (tap off) | Worn washer or cartridge | Sometimes improved by packing nut | Proper fix: new washer/cartridge |
| Spray/low flow | Clogged aerator | Twist off aerator to clean | Flush debris; descale; refit |
Tip: If your tap closes with multiple turns, it’s likely a compression type (washer-based). If it shuts in a crisp quarter-turn, it’s ceramic. For the latter, packing adjustments rarely affect spout drips; you’ll be looking at a cartridge swap. But even then, a gentle handle-end tweak can stop a stealthy weep while you source parts.
Pounds and Litres: The Real Cost of a Dripping Tap
Most households underestimate the bill impact. A modest drip—say one drop per second—can waste thousands of litres a year. With the average combined water bill in England & Wales at about £473 in 2024/25 (Ofwat), curbing wasted water won’t halve your bill, but it will shave a distinct slice, especially on a meter. When margins are tight, every litre counts. Here’s the back-of-the-envelope arithmetic I use in field pieces and audits:
- 1 drop/second ≈ 11–15 L/day → 4–5.5 m³/year
- Typical water + wastewater tariff ≈ £2.50–£3.20 per m³
- Annual waste from a “gentle” drip: roughly £10–£18
Case file: In a South London flat, a 1990s brass mixer wept at the handle and dripped from the spout. A careful packing-nut twist stopped the handle weep instantly; a £2 washer swap at the weekend ended the spout drip. The meter showed a 0.4 m³ monthly reduction—about £12–£15 per quarter saved, plus less limescale on the sink. Multiply this across millions of UK taps and the climate and cost benefits become undeniable. And unlike bigger retrofits, this fix fits into a tea break.
Pros and Cons of Quick Twists Versus Full Repairs
As a reporter who’s watched countless DIY triumphs—and the odd mishap—I rate the packing-nut twist as a legitimate first response. But clarity matters: it’s sometimes a stopgap. Here’s how it stacks up when weighed against full washer or cartridge replacement.
- Pros:
- Immediate: Stops many leaks in under a minute.
- No parts: Ideal when shops are shut or you’re between jobs.
- Low risk: Minimal disturbance to pipework.
- Cons:
- Temporary for spout drips: Worn washers/cartridges still need replacing.
- Overtightening risk: Can stiffen handles or damage ceramics.
- Not universal: Some designer taps hide or omit the nut.
My rule of thumb: If a quarter-turn cures the problem and the tap closes crisply, monitor for a week. If the drip returns, schedule a proper washer or cartridge change; keep PTFE tape, a mixed box of washers, and an adjustable spanner in a drawer. And if your isolation valves are stubborn, have a plumber service them—being able to shut off water quickly is the cheapest insurance in your kitchen.
Stopping a leak with a simple twist is one of those rare wins: quick, clean, and measurably effective. The technique won’t fix every faucet, but it buys time, cuts waste, and makes the eventual repair cheaper and calmer. Keep a cloth, a steady hand, and that quarter-turn in your toolkit; if needed, follow through with a fresh washer or cartridge over the weekend. After you silence your own drip, what other five-minute fixes—descaling an aerator, insulating a pipe, checking isolation valves—could trim your bills before the next statement arrives?
