Intro
On most jobs, water problems hit at the worst time. A valve fails. A flexi hose bursts. The client is panicking. The Quick Water Hack is a simple, reliable sequence you can use to stop a leak, cap a line, purge air, and restore water within minutes. You shut off fast, isolate the fault, fit a safe temporary cap, then bring the system back slowly. This guide shows you exactly how to run the Quick Water Hack, what tools you need, and how to avoid common mistakes.
Quick Answer
The Quick Water Hack is a step-by-step emergency routine: shut off the supply, drain pressure, isolate the faulty branch, install a push-fit or compression stop end, and bring water back slowly while purging air. It stops damage in 2–5 minutes and restores safe supply in about 10–20 minutes.

Key Takeaways
- Shut off, isolate, cap, and slowly restore flow. Keep it simple.
- Carry 15 mm and 22 mm stop ends. They solve 80% of bursts.
- Purge air at 3–4 outlets for 30–60 seconds each.
- Bring mains back slowly. Quarter-turns prevent water hammer.
- Document parts and time on site. Convert to a paid proposal the same day.
Main Content
What Is the Quick Water Hack?
The Quick Water Hack is a rapid control method for water issues. It uses basic valves, temporary caps, and a safe restart to stabilise a system. You stop the leak first. Then you isolate the faulty run. Then you cap it. Finally, you bring the water back in a controlled way.
It is not a permanent repair. It buys you safe time. It protects floors, ceilings, and electrics. It lets you plan the final fix without pressure.
When to Use the Quick Water Hack
Use the Quick Water Hack when:
- A flexi hose splits under a basin at 3 bar.
- A radiator valve starts weeping after a knock.
- A kitchen tap spindle fails and won’t close.
- A push-fit joint pops on a 15 mm cold feed.
- You need to swap a valve but can’t drain the full system today.
Avoid using it when the water is close to live electrics. Isolate power first. If the leak is from a lead main or asbestos cement pipe, stop, make safe, and plan a compliant replacement.
How to Do the Quick Water Hack (Step by Step)
Follow these steps. Keep your kit ready in one pouch. Time on site matters.
- Locate and Shut Off
- Find the main stop tap. Commonly under the kitchen sink or near the front entry.
- Turn clockwise until firm. Do not force. If seized, use water company curb stop if available.
- Target time: 30–60 seconds.
- Dump Pressure
- Open the lowest cold tap. Let water run for 10–20 seconds.
- Open the highest hot and cold taps to air the lines.
- This drops system pressure to near zero quickly.
- Isolate the Faulty Branch
- Close service valves (isolation valves) on the hot/cold feeds to the area.
- If none exist, you will cap at the nearest accessible point.
- Label valves with a marker if you add or find them.
- Cap or Stop-End the Line
- Cut back to clean, round pipe. Deburr the end.
- Fit a 15 mm or 22 mm push-fit stop end. Check the insertion depth (usually 20–27 mm).
- For compression caps, wrap 8–10 turns of PTFE on threads. Tighten snugly, then 1/4 turn more.
- Secure and Check
- Tug-test the fitting. It should not move.
- Place a towel or tray under the cap. Keep a bucket ready (10 litres is plenty).
- Slow Restart
- Close all open taps.
- Crack the main stop tap by 1/4 turn. Listen for flow.
- Open one cold tap to purge air for 30–60 seconds. Then close.
- Open the main tap another 1/4 turn. Repeat on one hot tap (if combi/instantaneous, follow manufacturer purge guidance).
- Full Purge
- Open 3–4 outlets around the property. Run each for 20–40 seconds.
- Check the capped point. Dry it with a tissue to spot weeping.
- Bring the main valve fully open only when stable.
- Monitor and Make Safe
- Watch for water hammer. If present, back off the main 1/8 turn.
- Log inlet pressure if you carry a gauge (3–5 bar typical mains). Fit a PRV later if needed.
- Photograph the cap and the leak area for records.
That’s the Quick Water Hack. In most homes, you’ll stabilise things in 10–20 minutes.
Carry a small, tight kit. It should fit in one organiser.
- Push-fit stop ends: 15 mm and 22 mm (2–4 of each)
- Compression stop ends: 15 mm and 22 mm
- PTFE tape (12 mm wide), jointing compound (where compliant)
- Pipe slice: 15 mm and 22 mm; deburring tool
- Adjustable spanner (200 mm), grips, and a valve key
- Towels, tray, and a 10 L bucket
- Pressure gauge (push-fit or washer-type) for quick checks
- Head torch and non-contact voltage tester (water near electrics)
Optional but handy:
- Pipe freezing kit for live caps (follow instructions carefully)
- Service valves (full-bore). Add them when you return for the permanent fix.
Common Problems and Fast Fixes
Airlocks After Restart
- Symptom: Sputtering taps, no hot flow on one outlet.
- Fix: Connect a hose between a working cold tap and the poor hot tap. Open hot first, then cold for 10–20 seconds to push air back. Repeat once.
Water Hammer on Refill
- Symptom: Loud banging when taps shut.
- Fix: Re-open mains slower. Add clipped support within 1–2 m of loose runs. Consider a mini arrestor near fast-closing valves.
Weeping Compression Cap
- Symptom: Tissue test shows damp at the nut.
- Fix: Back off, add 8–10 PTFE turns to threads, reseat, and tighten 1/4 turn. Ensure olive sits square. Do not overtighten.
Cloudy or Brown Water After Purge
- Symptom: Milky water or light brown tint.
- Fix: Run cold kitchen tap for 2–3 minutes. If brown persists longer than 10 minutes, advise mains disturbance; schedule a revisit.
No Isolation Valves Present
- Symptom: Can’t isolate a branch cleanly.
- Fix: Use main shut-off and cap as close as possible. Plan to fit full-bore service valves during the permanent repair.
Combi Boilers and Air
- Symptom: Boiler locks out with air after purge.
- Fix: Follow the boiler’s fill/vent steps. Bleed near the boiler first. Keep system pressure 1.2–1.5 bar cold, unless maker says otherwise.
Make It Stick: Notes, Proposals, and Payment
The Quick Water Hack stabilises the site fast. Now turn that into clear paperwork the client trusts.
- Log the time on site (arrived 10:20, stabilised 10:40), parts used (1Ă— 15 mm stop end), and photos.
- Outline the permanent repair: replace flexi hoses (2), fit two service valves, test to 3 bar, total time 1.5–2.0 hours.
- Send a clean proposal the same day. Clients approve faster when they see clear steps and photos.

FAQ
What is the Quick Water Hack?
It’s a fast, safe routine to stop leaks, cap faulty lines, purge air, and restore water. You shut off, isolate, cap with a stop end, and bring the mains back slowly. It buys time and prevents damage until you complete a permanent repair.
Is the Quick Water Hack a permanent fix?
No. It’s a temporary stabilisation. Use it to make the property safe and dry. Then schedule the full repair, add isolation valves, and test properly. Always tell the client what’s temporary and what’s permanent.
What sizes of stop ends should I carry?
Carry 15 mm and 22 mm as standard. These cover most domestic UK copper and plastic lines. If you work on commercial sites, add 28 mm. Keep at least two of each in your kit.
How long does the Quick Water Hack take?
Stopping the leak usually takes 2–5 minutes. Full stabilisation, purge, and checks take about 10–20 minutes. Add time for tricky access or seized valves.
Will this fix low water pressure?
It may help if trapped air was the cause. Purging can restore normal flow. If pressure remains low, check the stop tap, clogged aerators, or a faulty PRV. Log readings with a gauge and plan a follow-up.
Conclusion
The Quick Water Hack gives you control fast: shut off, isolate, cap, and restart slowly. It limits damage, keeps clients calm, and buys time for a proper repair. Do three things next: 1) Stock 15 mm and 22 mm caps and valves, 2) Practise the purge routine, and 3) Document every step with photos. For clean paperwork and faster approvals, turn your site notes into a proposal with solutions like Donizo. Move quickly, keep it safe, and finish strong with a clear plan.
