Leaking Tap Repair Guide for Fordingbridge Homeowners

Published July 2026 | Leaking Tap Repair

You spot it on a Tuesday morning - a steady drip from the kitchen tap that you're certain wasn't there last week. By the time you've made your coffee, the drip has become a trickle, and there's a faint water stain forming around the sink. In a town like Fordingbridge, where older properties are common and water pressure from the Hampshire mains can vary considerably, a leaking tap is one of the most frequent plumbing calls our engineers deal with.

Understanding What's Actually Going On

A leaking tap isn't just an annoyance - it's a symptom that something inside the tap mechanism has worn out or failed. At its core, a tap works by using a valve to control water flow. When you turn the handle, internal components compress against a valve seat to create a watertight seal. When that seal breaks down - because of wear, corrosion, or mineral build-up - water finds its way through even when the tap appears fully closed.

What you see as a "drip" is typically water escaping past a failed seal. Depending on the type of tap you have, the culprit could be a rubber washer, a ceramic disc cartridge, an O-ring, or the valve seat itself. The location of the drip matters too. Water coming from the spout points to one set of problems; water pooling around the base of the tap or around the handle points to another.

Our engineers regularly use the Voltrade GoFIX diagnostic tool to log tap faults before attending, which means we arrive with the right parts for your specific tap type rather than making repeat visits. It takes minutes to complete and typically saves at least one unnecessary call-out.

The Most Common Causes of a Leaking Tap

Worn Rubber Washers

This is by far the most common cause in traditional compression taps - the kind found in many older Fordingbridge homes, particularly Victorian and Edwardian terraces. Every time you turn the tap off, a rubber washer presses firmly against the valve seat to stop the water flow. Over years of use, that washer wears down, hardens, or perishes completely. The result is a tap that drips from the spout even when it's turned as far as it'll go.

Replacing a washer is one of the simpler plumbing tasks, but it does require isolating the water supply and sourcing the correct replacement washer size. Using the wrong size shifts the problem rather than solving it - and it's a mistake that's easy to make if you're working from memory rather than the original component.

Failed Ceramic Disc Cartridges

Many modern taps - particularly quarter-turn lever taps that have become popular in kitchen and bathroom renovations across Hampshire - use ceramic disc cartridges rather than rubber washers. These are generally more durable, but they're not immune to failure. Hard water causes mineral deposits to build up on the ceramic surfaces over time, and the discs can crack under sudden pressure changes or if the tap is forced beyond its travel.

Hampshire's water supply is classified as moderately hard to hard across many areas, which makes limescale accumulation a genuine factor for Fordingbridge properties. A failed ceramic cartridge typically needs replacing entirely rather than repairing - and cartridges are specific to the tap manufacturer, so correct identification matters.

Damaged O-Rings

If you notice water leaking around the base of the spout or tracking down from around the handle rather than dripping from the end, an O-ring is the likely culprit. O-rings are small rubber seals that sit between moving parts inside the tap body, preventing water from escaping at the joints. They're particularly prone to wear in mixer taps with swivel spouts, where constant rotation gradually degrades the rubber.

Like washers, O-rings are cheap components. The time and cost in the repair comes from the labour involved in accessing them correctly, and from matching the exact ring diameter and profile.

Corroded or Pitted Valve Seats

The valve seat is the fixed component inside the tap body that the washer presses against when you close the tap. If sediment accumulates on the seat over time, or if corrosion sets in, the washer can't create a proper seal even when it's brand new. This is a trickier repair because the seat itself needs to be reground or replaced. In some older taps, if the seat is too far gone, the practical route is replacing the entire tap unit rather than attempting an internal repair.

Loose or Degraded Packing

On older compression taps, there's packing material around the stem that creates a seal as you turn the handle. Over time, this packing compresses, shrinks, or degrades - and water starts to track out around the handle stem rather than staying inside the tap body. A leaking handle joint often points to packing that needs replacing, or in some cases just a packing nut that's worked loose and needs tightening. It's worth checking before assuming a more involved repair is necessary.

Solutions That Actually Work

The right fix depends entirely on what type of tap you have and where the leak originates. Here's a practical breakdown of the most common repair approaches.

For a dripping spout on a compression tap:

1. Turn off the water supply at the isolator valve under the sink, or at the mains stopcock if there's no isolator.
2. Open the tap fully to release any residual pressure in the pipe.
3. Remove the tap handle - usually held by a screw concealed under a decorative cover on top.
4. Unscrew the headgear (the internal mechanism) using an adjustable spanner, turning anticlockwise.
5. Remove the old washer from the bottom of the headgear and replace it with one of the correct size and thickness.
6. Reassemble in reverse order, restore the water supply, and check for leaks.

For a ceramic disc tap: The process is similar in principle, but instead of swapping a washer you're removing and replacing the entire ceramic cartridge. Cartridges are brand-specific, so you'll need to identify the manufacturer before ordering parts. Brands like Bristan, Grohe, and Hansgrohe all use distinct cartridge designs that aren't interchangeable.

For an O-ring leak around the spout base: This typically involves lifting or rotating the spout to access the O-rings seated around the spout inlet. Replacing them with the correct size, and applying a small amount of silicone grease before refitting, helps them seal properly and extends their working life considerably.

For a corroded valve seat: If you've already replaced the washer and the tap still drips, the seat is the next thing to look at. A plumber can regrind the seat using a seat dresser tool, restoring the smooth surface the washer needs to compress against. If the seat is too damaged to regrind, replacing the tap is the more reliable route.

When You Need a Professional vs Sorting It Yourself

Some tap repairs are well within reach for a confident DIYer with the right tools and a bit of patience. Others need a qualified plumber. Here's how to read the situation.

You can typically tackle it yourself if:

• You can locate and operate the isolator valve or stopcock successfully.
• The tap is a standard compression type with an accessible headgear.
• You can identify and source the correct replacement parts before you start.
• The tap body itself shows no signs of corrosion, cracking, or significant age-related wear.

Call a plumber if:

• You can't find or operate the isolation valve - attempting a repair without stopping the water supply risks a flood.
• The tap is part of a concealed or built-in system, which is common in modern bathroom installations.
• There's visible corrosion, damage to the pipe connections, or the tap body is cracked.
• It's a thermostatic mixer, filtered water tap, or any specialist installation.
• You've attempted the repair and it's still dripping - this usually means the valve seat is damaged and needs professional attention rather than another washer change.

For Fordingbridge homeowners in properties with older pipework - particularly anything pre-1970s - a professional assessment before you start is strongly advisable. Older compression fittings and galvanised pipework can react unpredictably when disturbed after decades of sitting undisturbed.

What to Expect from a Repair Visit

When you book a plumber for a leaking tap in Fordingbridge, most repairs take between 30 minutes and 90 minutes depending on the tap type and access. A straightforward washer replacement sits at the quicker end; a full tap replacement or a concealed system repair takes longer.

In terms of cost, a basic tap repair - replacing a washer, O-ring, or simple cartridge - typically costs between 80 and 150 pounds, including call-out and labour. Cartridge replacement on a branded mixer tap tends to sit in the 100 to 200 pound range, factoring in the cost of the part itself. If a full tap replacement is needed, expect to pay between 150 and 350 pounds, depending on the tap unit you choose and the complexity of the installation.

Our engineers covering the Hampshire area carry a range of common washers, O-rings, and cartridges as standard, which means most repairs are completed in a single visit. For less common or high-end tap models, parts may need to be ordered, but we'll flag this before confirming the booking so you know what to expect from the outset.

Before the engineer arrives, it's worth locating your mains stopcock - typically under the kitchen sink, in a utility cupboard, or near the front door in older properties. Knowing where it is saves time and removes stress if the supply needs isolating quickly during the repair.

Common Questions from Fordingbridge Homeowners

How much water does a dripping tap actually waste?

A tap dripping roughly once per second wastes somewhere in the region of 30 to 40 litres of water per day. Over a month, that's over a thousand litres from a single tap. For a metered household, this shows up on your water bill more noticeably than most people expect - and that's before accounting for the ongoing wear that continuous dripping causes to the tap body, the valve seat, and in some cases the sink itself.

Can I use plumber's tape to temporarily stop a leaking tap?

PTFE tape is useful for sealing threaded pipe joints during a repair, but it won't stop a dripping spout or a weeping handle. A drip from a worn washer or failed cartridge needs the internal component replaced, not anything applied to the outside of the tap. It's a common workaround that simply doesn't address where the fault actually is, and can occasionally make the repair more complicated when a plumber eventually attends.

My tap is relatively new but it's already dripping. What's gone wrong?

New taps can drip for several reasons. Incorrect installation is the most common - if the cartridge wasn't seated properly or the tap wasn't aligned correctly during fitting, the seal won't hold. A faulty cartridge from the manufacturer is less common but does happen. It's also worth checking whether your water pressure is within the tap's rated specification. Some taps are rated for maximum pressures of around 1 to 3 bar, and in parts of Hampshire mains pressure can exceed this, requiring a pressure reducing valve on the incoming supply rather than a tap repair as such.

Is it worth repairing an old tap or better to just replace it?

If the tap body is in solid condition and it's only the internal components that have failed, a repair is almost always more cost-effective than replacement. If the tap is heavily corroded, the body is cracked, or you've had repeated repairs that haven't held for long, replacement makes more practical sense. Our engineers will give you a clear assessment on the day, including whether parts are still readily available for older tap models - which can be a deciding factor for taps that are more than 20 to 25 years old.
