Leaking Tap Repair in Totton - A Homeowner's Guide

Published September 2026 | Leaking Tap Repair

You notice a drip from the kitchen tap at 11pm on a Sunday. By morning there's a small puddle forming around the base and the dripping has got faster. It's tempting to put a cloth under it and deal with it later, but that tap isn't going to fix itself, and in a hard-water area like Hampshire, a small drip can escalate into a much bigger problem faster than most people expect.

Understanding What's Actually Happening Inside Your Tap

A dripping tap means water is getting past a seal or valve it shouldn't be able to. The internal components of a tap are designed to create a watertight closure when you turn the handle off. When that seal breaks down through wear, corrosion, or physical damage, water finds a way through and you end up with that familiar, infuriating drip.

There are two broad categories of taps in UK homes: traditional pillar taps with separate hot and cold handles, and monobloc mixer taps with a single lever or handle. Each has different internals, but the root causes of leaks are often similar. Older properties in Totton tend to have pillar taps in bathrooms especially, while kitchens are more likely to have been updated to modern mixer styles.

It's also worth understanding the scale of the problem before you dismiss it. A tap dripping at roughly one drop per second can waste somewhere between 5,000 and 10,000 litres of water per year. If you're on a water meter, which is increasingly common across Hampshire, that adds a real and measurable amount to your bill. Getting it sorted quickly is almost always cheaper than leaving it.

The Most Common Causes of a Leaking Tap

Worn Washers

In traditional pillar taps, a worn washer is the most common culprit by some distance. Every time you turn a tap off, a rubber washer presses against a valve seat to block the flow. Over years of use, that washer gets compressed, hardens, or cracks. When it no longer forms a proper seal, water drips through - typically from the spout itself.

Replacing a washer is one of the more manageable DIY plumbing jobs, but it does require turning off the water supply, disassembling the tap head, and sourcing the correct replacement washer. Get the size wrong and it won't seal properly, so measure carefully before ordering.

Damaged O-Rings

O-rings are small rubber rings that seal around the spindle of a tap. When these deteriorate, you'll typically see water leaking around the handle or from the base of the tap rather than from the spout. O-ring failure is especially common in mixer taps and cartridge-style fittings.

In Hampshire's hard-water zones, limescale build-up can accelerate the degradation of O-rings over time, making them brittle and prone to cracking well before you'd expect.

Corroded or Pitted Valve Seat

The valve seat is the surface the washer presses against to stop water flow. If limescale or debris has corroded or pitted the seat, even a brand-new washer won't create a proper seal. You can sometimes re-grind a valve seat using a specialist tool, but if it's badly damaged it may need replacing entirely. This is one of the reasons a drip can come back quickly after a DIY washer swap.

Ceramic Disc Failure

Many modern taps use ceramic disc cartridges instead of traditional washers. These are generally more durable, but ceramic discs can crack or become contaminated with debris and limescale. A failed ceramic cartridge typically results in either a persistent drip or a tap that's suddenly difficult to control. Replacing the cartridge usually resolves the issue, though it's important to match the replacement exactly to the original manufacturer's specification - Bristan, Grohe, and Franke are among the common brands found in Totton kitchens and bathrooms.

Loose Packing Nut

On some older taps, there's a packing nut around the spindle. If this works loose over time, water can seep up around the handle. Occasionally this is fixable with a careful tighten using an adjustable spanner, though the packing material underneath may also need replacing. Don't overtighten - brass fittings on old taps can strip or crack.

Solutions That Actually Work

The right fix depends on what type of tap you have and which component has failed. Here's how to approach the most common scenario - a traditional pillar tap dripping from the spout:

1. Turn off the water supply - either at the isolator valve under the sink or at the main stopcock if there's no isolator.
2. Open the tap fully to release any remaining pressure in the line.
3. Remove the tap handle, usually by unscrewing a small screw hidden under a decorative cap.
4. Use an adjustable spanner to unscrew the headgear nut and pull out the spindle.
5. Locate the washer at the bottom of the spindle. Note the size before removing it - most UK taps use either a 1/2 inch or 3/4 inch washer.
6. Fit the new washer, reassemble the tap, and restore the water supply.
7. Test thoroughly and check for any weeping around the headgear nut.

While you've got the tap apart, run a finger around the valve seat. If it feels rough or pitted rather than smooth, a new washer alone may not last long. Our engineers recommend using the Voltrade GoFIX diagnostic tool before you order parts - it can help identify your tap type and the most likely cause of the fault, which saves you ordering the wrong washer or cartridge.

For ceramic cartridge taps, the process is slightly different. You'll need to identify the exact cartridge - check the tap brand, and if possible look up the model number. Replacement cartridges for common brands are widely available from plumbing merchants or online, and the swap itself is often simpler than a traditional washer job once you've got the right part in hand.

For O-ring leaks around the handle or body, you'll need to disassemble further to reach the rings. Replace all the O-rings in the assembly while you're in there - they'll all be at a similar age and the cost difference is negligible.

When You Need a Professional vs Sorting It Yourself

This is something our engineers get asked regularly from Totton homeowners who are reasonably handy but aren't sure how complex the job is going to get.

DIY is a reasonable option if:

• You have a dripping traditional pillar tap and you're comfortable turning off the water supply.
• The tap is modern and you can identify the cartridge make and model without too much difficulty.
• You've attempted basic plumbing tasks before and you know how to check for residual pressure before disassembling anything.

Call a plumber if:

• The tap is old or heavily corroded, or the headgear nut is seized. Forcing a seized fitting without the right approach can crack pipework, which turns a modest job into a much larger one.
• The leak is coming from the joint between the tap and the worktop or basin, as this often means the tap body itself needs replacing.
• You've already replaced the washer and it's still dripping - this typically points to a damaged valve seat, which needs a different approach.
• You're not confident finding or operating the correct isolator valve. In some older Hampshire properties, isolator valves under the sink either don't function properly or were never fitted, meaning you need to locate the main stopcock - which isn't always obvious.
• The leaking tap is in a difficult access point, such as behind a bath panel or in a confined airing cupboard.

One practical rule: if you've had a go at a basic repair and it hasn't worked, stop disassembling the same tap repeatedly. You risk damaging soft brass components, which can make the eventual repair more involved and more expensive.

What to Expect from a Repair Visit

Most leaking tap repairs are something a qualified plumber can resolve in under an hour, provided the fault type is identified and parts are either on the van or sourced beforehand. Using GoFIX before booking can significantly speed this up, since the engineer arrives knowing what they're likely dealing with.

On a typical visit, the engineer will inspect the tap and confirm the cause of the leak, turn off the water supply and disassemble the tap, replace the faulty component (washer, O-rings, or ceramic cartridge), check the valve seat and re-grind if needed, reassemble and test for leaks, and usually have a quick look at the isolator valves and surrounding pipework while they're in the area.

In terms of cost, a basic washer or O-ring replacement in Totton typically comes to between 60 and 120 pounds including labour for a single tap. If a ceramic cartridge is needed, parts can add anywhere from 20 to 60 pounds depending on the brand. A full tap replacement - where repair isn't the most sensible option - typically costs between 100 and 200 pounds for labour, not including the cost of the new tap itself.

Most plumbers working across Totton and the wider Hampshire area will give you a clear price before starting work. If a call-out fee applies, confirm upfront whether it's included in the final repair price or charged on top.

Common Questions from Totton Homeowners

Can I fix a leaking tap if I've never done plumbing before?

A basic washer replacement is one of the more accessible DIY plumbing tasks, but it does involve turning off your water supply and using tools with some confidence. If you know where your stopcock or isolator valves are and you're comfortable working with an adjustable spanner, a dripping traditional pillar tap is manageable. Ceramic cartridge taps are also reasonably simple once you have the correct part. If the tap is old or corroded, though, it's worth calling a plumber - a seized headgear nut can cause real damage if forced without the right technique.

How do I know if my valve seat needs replacing as well as the washer?

The clearest sign is when a drip returns fairly quickly after a washer replacement - sometimes within days. When you have the tap apart, run a fingertip around the valve seat. A healthy seat feels smooth and even; a damaged one will feel rough, pitted, or have visible scoring. A plumber can re-grind a mildly damaged seat using a tap reseating tool. If the damage is severe, the seat itself may need replacing, which is a slightly more involved job but still well within the scope of a standard repair visit.

My tap has started dripping again after I fixed it six months ago - what's going on?

This usually points to one of two things: either the valve seat was already damaged when you replaced the washer, meaning the new washer is now wearing unevenly, or the replacement washer wasn't the correct size or material for that tap. It can also happen when limescale build-up accelerates wear - common in hard-water parts of Hampshire. It's worth getting a plumber to inspect the full assembly rather than just swapping the washer again, as repeating the same fix without addressing the underlying cause tends to give diminishing returns.

Should I repair or replace an old leaking tap?

It depends on the age and condition of the tap. One that's less than ten years old and structurally sound is almost always worth repairing - parts are cheap and labour time is short. An older tap with heavy limescale, a corroded body, or seized fittings can cost nearly as much to repair as to replace, especially if the parts are no longer in production. Our engineers generally advise replacement when the estimated repair cost approaches 60 to 70 percent of a new tap's installed price - at that point, you're better off with a fresh fitting and a fresh guarantee.
