Leaking Tap Repair Guide Bridgwater

Published June 2026 | Leaking tap repair

We asked our plumber engineers the questions Bridgwater homeowners ask most about leaking taps. Here's what they told us.

Why has my tap started dripping and what causes it?

A dripping tap usually comes down to worn internal components, and it's one of the most common plumbing issues we see across Somerset. The main culprit is typically a deteriorated washer or O-ring seal that no longer creates a watertight barrier when you turn the tap off.

In traditional taps, rubber washers sit against the valve seat and over time they compress, crack, or perish from constant use and mineral deposits in the water. Modern mixer taps often use ceramic disc cartridges instead, and these can develop hairline cracks or get damaged by limescale buildup - something we see quite frequently in Bridgwater's hard water areas.

Other causes include loose packing nuts around the tap spindle, corroded valve seats, or damaged spindles themselves. Sometimes the issue isn't the tap at all but high water pressure causing seals to fail prematurely. Our engineers also find that cheaper tap mechanisms simply wear out faster than quality brands like Grohe or Hansgrohe.

Temperature changes can worsen the problem too. When hot water flows through, metal components expand differently than rubber seals, creating gaps where water can escape. This is why you might notice the drip getting worse after running hot water.

Can I fix a dripping tap myself or do I need a plumber?

Many homeowners can tackle basic tap repairs themselves with the right tools and a bit of patience. If it's a simple washer replacement on a traditional tap, you'll need an adjustable spanner, screwdrivers, and replacement washers from any hardware store.

Start by turning off the water supply at the isolator valves under the sink or at the mains. Remove the tap handle (often held by a small screw under a decorative cap), then unscrew the headgear to access the washer. Replace the washer and any O-rings, reassemble, and test.

However, mixer taps with ceramic cartridges are trickier. The cartridges cost £15-£40 each and you need to match the exact model. Getting it wrong means another trip to the shops and potentially damaging the tap body.

Our Bridgwater engineers recommend calling a professional if you encounter seized components, need specialist tools, or discover the valve seat needs recutting. What starts as a £5 washer replacement can quickly become a £200 repair if things go wrong.

Also consider your time and stress levels. A qualified plumber will complete the job in 30-60 minutes with guaranteed results, typically charging £80-£150 for a simple repair including parts and labour.

How much does it cost to repair a leaking tap in 2026?

Tap repair costs in the UK vary depending on the complexity of the job and your location. In Bridgwater and across Somerset, you can expect to pay £80-£150 for a standard callout and basic repair like replacing washers or O-rings.

If the job requires a ceramic cartridge replacement, add £15-£40 for the part itself. Premium cartridges for high-end taps can cost £60-£80. Emergency callouts outside normal working hours typically attract a £50-£100 surcharge.

More complex repairs involving valve seat recutting or spindle replacement range from £120-£200. If the tap body is damaged and needs complete replacement, budget £150-£300 plus the cost of a new tap unit.

Many plumbers include basic parts like washers and O-rings in their callout charge, but larger components are usually itemised separately. Always ask for a quote before work begins, especially if multiple taps need attention.

Consider that a small drip can waste 15 litres of water daily, adding £3-£5 monthly to your bill. Over a year, professional repair pays for itself compared to ignoring the problem. Our engineers often find that customers who delay repairs end up with more expensive issues like damaged worktops or cabinet floors.

What tools and parts will I need for DIY tap repair?

For basic tap maintenance, you'll need a decent toolkit. Essential items include adjustable spanners (10mm and 15mm are most common), flat and Phillips head screwdrivers, needle-nose pliers, and a headlamp or torch for working in dark cupboards.

Stock up on common repair parts: assorted tap washers (½ inch, ¾ inch), O-ring sets in various sizes, and PTFE tape for thread sealing. These cost under £20 total and handle most simple repairs. Keep penetrating oil like WD-40 handy for seized components.

For mixer taps, you might need specific tools depending on the brand. Some require Allen keys or specialist cartridge pullers. Check the manufacturer's instructions or our Voltrade GoFIX diagnostic tool to identify exact requirements.

Quality matters with replacement parts. Cheap washers from pound shops often fail within months, while proper plumbers' merchants stock durable components. Brands like Pegler and Bristan offer reliable replacement parts that our engineers trust.

Don't forget safety equipment - rubber gloves protect against sharp edges and dirty water, while knee pads make working under sinks more comfortable. A water-absorbent cloth and bucket are essential for catching spills during disassembly.

How do I identify what type of tap mechanism I have?

Understanding your tap type determines the repair approach and parts needed. Traditional taps have separate hot and cold handles that turn multiple times to open fully. These use washer-and-seat mechanisms that are relatively simple to service.

Mixer taps combine hot and cold water through a single spout. Quarter-turn mixers move from off to full flow in 90 degrees and typically use ceramic disc cartridges. Half-turn mixers require 180 degrees and might use ceramic discs or ball valves.

Remove the handle to see inside. Traditional taps show a threaded spindle with a washer at the bottom. Ceramic disc taps have a cylindrical cartridge that lifts out as one piece. Ball-valve taps contain a perforated metal ball that rotates to control flow.

Check for manufacturer markings on the tap body or handle. Common UK brands include Bristan, Triton, and Mira. Our engineers in Bridgwater often encounter older Adamsez and Armitage Shanks taps in period properties - these sometimes need obsolete parts sourced from specialist suppliers.

If you're unsure, take photos before dismantling anything. Our Voltrade GoFIX app can help identify tap types from images and suggest appropriate repair procedures.

Why does my tap keep dripping even after I've changed the washer?

A persistent drip after washer replacement usually indicates a damaged valve seat - the metal surface the washer seals against. Over time, limescale and sediment score the seat, creating grooves that prevent proper sealing no matter how new the washer is.

Valve seats can be recut using a special tool that removes a thin layer of metal to restore a smooth surface. This requires experience and the right equipment - something our engineers handle regularly but isn't really a DIY job for most homeowners.

Another possibility is using the wrong washer size or type. Washers must match the seat diameter exactly, and the material matters too. Some modern taps need specific synthetic rubber compounds rather than traditional black rubber washers.

Check you've tightened the headgear properly - too loose and water bypasses the washer, too tight and you can deform the washer or crack the seat. There's a sweet spot that comes with experience.

Sometimes the problem lies elsewhere entirely. High water pressure, a faulty pressure reducing valve, or expansion issues in the hot water system can cause drips that appear to come from the tap but actually originate from loose joints or worn pipework hidden behind walls.

When should I replace the entire tap rather than repair it?

Consider replacement when repair costs approach 60-70% of a new tap's price. If multiple components are failing simultaneously - cartridge, spindle, and seals - it's often more economical to upgrade the entire unit.

Age plays a factor too. Taps over 15-20 years old may have obsolete parts or use outdated mechanisms that are prone to future failures. Our Somerset engineers particularly recommend replacement for pre-1990s taps that can't achieve modern water efficiency standards.

Chronic issues like recurring leaks every few months signal fundamental problems with the tap design or installation. Sometimes the tap isn't suited to your water pressure or quality - hard water areas around Bridgwater can be particularly harsh on certain brands.

Visual deterioration matters for resale value. Heavily corroded chrome, cracked ceramic, or worn-out handles detract from kitchen or bathroom appeal. Modern taps offer better flow rates, temperature control, and water-saving features.

If you're renovating anyway, factor in labour costs. Installing a new tap during kitchen or bathroom work costs £50-£80, but as a standalone job it's £120-£180. Sometimes waiting makes financial sense, other times immediate replacement is more practical.

What's the difference between repairing a kitchen tap versus a bathroom tap?

Kitchen taps work harder than bathroom taps, facing constant use, food debris, and temperature extremes. They're typically larger with more solid mechanisms, but the constant cycling between hot and cold water puts stress on seals and cartridges.

Access differs significantly. Kitchen taps often sit in tight spaces behind sinks filled with cleaning products and waste disposal units. Our Bridgwater engineers need more time to work safely in these cramped conditions, sometimes requiring worktop removal for complex repairs.

Water pressure considerations vary too. Kitchen taps usually connect directly to mains pressure, while bathroom taps might feed from header tanks or combination boilers. This affects the types of seals and mechanisms that work reliably.

Bathroom taps encounter different contaminants - soap residue, toothpaste, and hair products can clog aerators and damage internal components differently than kitchen grime. However, they typically see gentler use patterns with longer periods between operation.

Cost differences reflect complexity and access. Kitchen tap repairs typically cost £20-£40 more due to the additional time needed to work around obstacles and the generally more expensive replacement parts required for heavy-duty mechanisms.

How can I prevent my taps from developing leaks in the future?

Regular maintenance prevents most tap problems before they start. Clean aerators monthly to prevent limescale buildup that can damage internal seals. Unscrew the aerator, soak in white vinegar overnight, then scrub with an old toothbrush.

Don't overtighten taps when closing them. Excessive force wears washers and valve seats prematurely. Teach family members to close taps gently - the mechanism should stop the flow without forcing the handle.

Consider installing a water softener if you live in Bridgwater's harder water areas. Limescale is the enemy of all plumbing components, particularly the precise tolerances in ceramic disc cartridges. Softened water extends tap life significantly.

Address small issues promptly. A slight stiffness in operation or occasional drip often signals early wear that's easily corrected. Waiting until complete failure means more expensive repairs and potential water damage.

Annual plumbing checks catch problems early. Our engineers recommend this especially for homes over 10 years old or in areas with aggressive water chemistry. Early intervention saves money and prevents the inconvenience of emergency repairs.

What should I do if water won't stop flowing from the tap?

A tap that won't stop flowing is a plumbing emergency requiring immediate action. First, locate and turn off the water supply - either the isolation valves under the sink or the mains stopcock if isolator valves are seized or missing.

This usually indicates a completely failed mechanism inside the tap body. The spindle might have sheared, the cartridge could have disintegrated, or internal components have come loose and jammed open. Don't try forcing the handle as this can worsen the damage.

Call an emergency plumber immediately. Water waste from a fully open tap can reach 15-20 litres per minute, quickly flooding your property and creating expensive damage. Our emergency engineers across Somerset typically respond within 2-4 hours for this type of call.

While waiting for help, position buckets to catch water and move any electrical items away from the area. Check that water isn't reaching electrical sockets or equipment that could create safety hazards.

Emergency repairs for seized or failed taps typically cost £150-£250 including callout charges and basic parts. Complete tap replacement might be necessary if the body is damaged, adding £100-£200 for a mid-range unit plus fitting time.

This scenario highlights why knowing your stopcock location matters. Every household member should know how to shut off the water supply in emergencies - it can prevent thousands of pounds of water damage while you wait for professional help.

A leaking tap might seem like a minor annoyance, but addressing it promptly prevents water waste, reduces bills, and avoids the risk of more serious damage. Whether you tackle basic repairs yourself or call our experienced engineers, acting quickly always saves money in the long run.

How long does a typical tap repair take?

Most basic tap repairs take 30-60 minutes for a professional plumber. Simple washer replacements are usually completed within 30 minutes, while ceramic cartridge replacements or more complex issues requiring valve seat work can take up to 90 minutes. DIY repairs typically take longer, especially for inexperienced homeowners who might need 2-3 hours for the same job.

Will my water be turned off during the entire repair?

Water supply is only turned off while the actual repair work takes place, usually 20-45 minutes depending on the complexity. Professional plumbers can often isolate just the affected tap using local isolation valves, leaving the rest of your water supply unaffected. If mains water needs shutting off, this is typically for less than an hour.

Can a dripping tap cause serious damage to my home?

Yes, even a small drip can cause significant problems over time. Constant moisture can damage worktops, cupboard floors, and promote mould growth. A persistent drip can waste over 3,000 litres annually, adding £30-£50 to water bills. More seriously, if the leak worsens into a constant flow, it can cause flooding and expensive water damage to floors and ceilings below.

What's the most common mistake people make when repairing taps?

The biggest mistake is using excessive force when components are seized or stuck. This often damages the tap body beyond repair, turning a simple £10 washer replacement into a £200 tap replacement job. Always use proper tools, apply penetrating oil to seized components, and call a professional if you encounter significant resistance during disassembly.
