NUA HELP / SUPPLY
Airlocks
Air trapped in pipework can sometimes interrupt or reduce flow at an outlet.
Demo information only. For a real plumbing or water-supply issue, use qualified local guidance.
What you may notice
Flow may splutter, stop temporarily, or vary between taps.
Start with simple checks
Check whether the issue is isolated to one outlet and whether other cold-water taps are operating normally.
If it continues
A persistent issue may need further investigation rather than repeated DIY troubleshooting.
