Hot tub losing water? What normal evaporation looks like, where hot tubs and swim spas leak, the overnight mark test, and when to call a leak specialist.

Swimming pool losing water? How the pump on, pump off test separates plant room and pipework leaks from the shell, what to check yourself, and when to call DCI.

Water damaged ceiling repair cost in the UK: what a stain, a blown section or a whole new ceiling costs to put right, and what your home insurance will pay for.

Landlord responsibility for a water leak in the UK: section 11 repairs, what the tenant pays, the water bill, deposits and the first 24 hours for both sides.

Water coming through your ceiling from the flat above? Who pays, who fixes it, what the lease and block insurance do, and how the leak gets traced.

Tracer gas leak detection explained: the 5% hydrogen mix, how the pipe is drained and filled, what it finds under floors and drives, and what it cannot find.

Leak detection equipment explained: correlators, tracer gas, thermal imaging and moisture meters. What each finds, what it cannot do, and who to call.

Central heating leak sealer can close a tiny weep, but it hides the leak rather than fixing it. What it seals, the risks, and when to find the leak instead.

Why combi boilers lose pressure, how to repressurise to 1 to 1.5 bar, and how to tell a valve fault from a hidden heating leak.

Around 97% of UK buildings policies include trace and access cover, usually £5,000 to £10,000. What it pays for, what it excludes and how to claim it.

E119 on a Baxi or Potterton boiler is a low water pressure fault that stops the boiler. This guide covers how to repressurise the system yourself, and how to tell whether the pressure loss is a one-off or a leak in buried pipework. It also sets out which faults belong to a Gas Safe heating engineer rather than a leak detection specialist.

On a Glow-worm boiler, F1 is an ignition fault rather than the low pressure code many people expect it to be. This guide explains what the boiler is reporting, the checks a householder can safely make, and why the repair itself is Gas Safe work. It also covers the separate question of a pressure gauge that keeps falling.

F1 on an Ideal Logic means the sealed heating system has lost pressure. This guide covers what Ideal says the code means, how to repressurise safely, and the one test that separates a harmless top-up from a hidden leak.

A bath overflow leak only shows up once the bath is full, which is exactly why it gets missed for so long. Here’s how the overflow and banjo fitting fail, and why the leak seems to come and go.

What the F22 code on a Vaillant boiler actually means and how to top the system back up safely. It also covers the simple test that separates a one-off pressure drop from a hidden heating leak, and when the job belongs to a Gas Safe registered engineer instead.

A Vaillant F75 means the boiler detected no change in water pressure when the pump started, so it locked out. This guide explains the fault, the checks you can safely make yourself, and the one pattern that turns it into a leak question rather than a boiler one.

Homes near the Cornwall and Devon coast deal with a form of damp most inland properties never see: hygroscopic salt contamination that pulls moisture from the air itself and can throw off a moisture meter reading. Here is how to tell salt damp apart from sea-spray penetration and a genuine hidden leak.

A boiler that cuts out on a cold morning, often with a gurgling sound beforehand, is usually a frozen condensate pipe rather than anything more serious. Here is how to recognise it, thaw it safely, and stop it happening again this winter.

Suspect a leak under the bath but dreading the tiles coming off? Here’s how to test what’s happening before anyone reaches for a hammer, and how professional detection narrows the access needed.

Owners of second homes and holiday cottages across Cornwall and Devon face the same choice every autumn: drain the system down completely or leave the heating ticking over. Each option carries its own leak risk. Here is how to weigh them up and what to check before you leave.

Long private water networks, dozens of pitch isolation valves and a hard seasonal opening deadline make caravan and holiday parks one of the trickiest leak jobs in the South West. Here is how park operators find hidden leaks fast, without digging up the whole site.

An overflow pipe dripping outside your home is a warning sign, not just a nuisance. Here’s how to work out which system it belongs to and what it means before it stains a wall or wastes water for months.
