Leaking flexible tap hose: what a replacement must match

Identify the hose without disturbing it

A tap can have flexible supply tails beneath the sink and, on a pull-out model, a separate moving hose for the spray. These have different roles. Describe where the water appears, whether it is continuous and whether it changes when the tap or pull-out spray is used. A safe wider photograph can help identify the arrangement after the initial enquiry.

Do not pull on the hose, bend it sharply or run your fingers along damaged braiding. Keep clear where water is near electrical equipment. If a familiar isolation control is safely accessible and operates normally, it may limit the escape; do not force a corroded valve or reach through a wet appliance space to find one.

The leak may be in the hose or at its connection

Water at one end can originate from a seal, a connection or the hose assembly itself. Moisture can also travel along the outside from another leaking part. The plumber should establish the first wet point and assess the assembly before deciding whether a connection can be repaired or the complete hose needs renewal.

Visible deterioration, a damaged crimp or a strained route changes the decision. The BSRIA flexible-hose guidance covers selection and installation as a system issue, not simply matching a thread. A fitting that appears to screw on is not enough to establish suitability for the water service, operating conditions and manufacturer requirements.

Specify the replacement rather than choosing by length alone

The correct hose needs compatible ends, dimensions and suitability for its intended use. A tap manufacturer may specify a particular tail or connection arrangement. Keep the product reference where available and identify any previous non-original alteration. The plumber should confirm the actual replacement rather than assume all braided connectors are interchangeable.

Length matters because the hose needs a suitable route without tension, sharp bends or an inappropriate coil forced into a small space. The surrounding cupboard and fitting positions affect that route. A longer hose is not automatically a better solution, and a different bore or connection can affect installation suitability. These are specification decisions for the repair.

Check why the original hose was stressed

A loose tap, moved appliance or trapped connector can place unwanted load on a hose. If the tap has been rotating at its base or storage items press against the plumbing, mention that history. Replacing the component without correcting the physical arrangement can leave the replacement exposed to the same problem.

The inspection should consider nearby hoses and accessible connections, while keeping the agreed scope clear. Similar age alone does not prove every connector has failed, but visible deterioration elsewhere should be reported. Ask which components need immediate replacement and which findings are recommendations for separate work, rather than receiving an unexplained bundle of new fittings.

Agree isolation, cupboard access and any return visit

The plumber needs a safe way to isolate the affected supply and space to reach both ends. A deep sink bowl, integrated appliance or fitted drawer can obstruct access. If a local valve also needs repair, that should be explained before the connection is opened. A leaking valve cannot simply be assumed to provide reliable isolation.

Cost factors include the compatible hose, diagnosis, access, isolation work and any necessary tap or appliance movement. Where a special part must be ordered, agree how the supply and fitting will be left. A temporary measure should have clear use restrictions and a planned next step; it should not be presented as equivalent to the permanent replacement.

Check the new route and all disturbed joints

After installation, the repaired supply should be restored under control and the relevant connections checked. The hose needs to remain correctly routed once drawers, appliances and stored items return to their normal positions. A route that looks clear with an empty cupboard can become trapped when the cabinet is used.

Keep the replacement details and any advice on maintenance access. The repair record should identify whether the failure involved the hose, its connection or another component, and whether adjacent damage remains. If water reappears, stop using the affected fitting where appropriate and report the location rather than attempting further tightening without a diagnosis.

Report an active hose leak clearly

Loyal Plumbers repairs leaking tap connections throughout London and inside the M25. Send the postcode, whether water is still escaping, the location of the hose and any safe isolation already completed. Mention electrical hazards and restricted access. The team can request photographs by email after the enquiry; there is no need to remove a fitting to provide them.
