Leaking Tap Repair in Solihull - A Practical Guide for West Midlands Homeowners

Published September 2026 | Leaking Tap Repair

You notice it first thing in the morning - that steady drip from the kitchen tap you were sure you'd turned off properly the night before. By the time you've brewed your coffee, it's dripped a dozen times, and within a few days it becomes the kind of background noise you can't quite tune out. For homeowners across Solihull, a leaking tap can seem like a minor annoyance, but left alone it wastes water, pushes up your bills, and can quietly damage the surrounding fixtures and cabinetry.

Understanding What's Actually Happening Inside Your Tap

A tap is a valve, and like any valve, it relies on seals and moving parts to control water flow. When it drips, something in that sealing system has broken down. The water supply to your home is under constant pressure - typically between 1 and 3 bar in most Solihull properties - and that pressure never stops pushing against whatever's holding it back inside the tap body. The moment a seal weakens, water finds its way through.

The key thing to understand is that dripping taps don't fix themselves. Continued water movement over a failing component typically accelerates the wear, which means a small drip can become a steady trickle within weeks or months. Our engineers use the Voltrade GoFIX diagnostic tool to identify exactly which internal component is failing before opening up the tap, which saves time and avoids unnecessary part replacements.

The type of tap you have matters a great deal here. Older properties in Solihull - particularly those built before the 1980s - commonly have traditional compression taps with rubber washers. More recent homes tend to have ceramic disc cartridge taps, mixer taps, or monobloc units. Each type fails differently, and the repair approach is different too.

The Most Common Causes of a Leaking Tap

Worn Rubber Washers

This is the most common cause in traditional pillar taps and older compression-style fittings. Every time you turn the tap off, a rubber washer is pressed against a valve seat to form a watertight seal. Over time - typically after several years of daily use - that rubber hardens, cracks, or distorts. Once the washer can no longer create a complete seal, water drips through. This is one of the more accessible DIY repairs if you're comfortable isolating the water supply and dismantling the tap head.

Damaged O-Rings

If the leak is appearing around the base of the tap spout rather than from the spout itself, an O-ring is the likely culprit. These small rubber rings seal the moving parts of the tap body - particularly the spindle - and they degrade with use and exposure to cleaning chemicals. Mixer taps and swivel-spout taps are particularly prone to this kind of leak. Replacing an O-ring requires removing the spout or body cap, and having the right size ring on hand before you start is essential.

A Worn Ceramic Disc Cartridge

Ceramic disc taps - now common in most homes built or renovated in the last two decades - use two precision-ground ceramic discs that rotate against each other to control water flow. When these discs chip, crack, or collect limescale build-up, they can no longer form a complete seal. In areas with harder water, including parts of the West Midlands, limescale is a particularly common reason for cartridge failure. Replacing a ceramic cartridge is generally a job that takes less than an hour for a competent plumber, though getting the exact cartridge model matters - the wrong size simply won't fit.

Corrosion on the Valve Seat

The valve seat is the surface inside the tap body that the washer presses against. If sediment or mineral deposits build up on this surface, or if it corrodes, the washer can't form a proper seal even when it's new. In this situation, replacing the washer alone won't solve the problem - the seat itself needs to be reground or replaced. This is a job for a plumber, as it requires a specialist tool called a seat grinder that most households don't keep in the cupboard under the stairs.

Loose Packing Nut

On older compression taps, a packing nut sits just beneath the handle and compresses a seal around the spindle. If this nut works loose over time - which it can from repeated use - water can track up around the spindle and appear at the base of the handle rather than from the spout. This is sometimes fixable with a spanner to re-tighten the nut, though if the packing material inside has deteriorated, it will need replacing.

Solutions That Actually Work

The right repair depends on which type of tap you have and which component has failed. Here's a practical breakdown of what's involved.

For a dripping compression tap with a worn washer:

1. Turn off the water supply at the isolation valve under the sink, or at the mains stopcock if there's no isolation valve present.
2. Turn the tap on to release any remaining water pressure in the pipes.
3. Remove the tap handle - this usually means prising off a decorative cap and unscrewing the screw underneath.
4. Use a spanner to unscrew the packing nut and withdraw the spindle.
5. At the base of the spindle you'll find the rubber washer held in place by a small nut. Remove it, take it to a plumber's merchant to match the size, and fit the new one.
6. Reassemble in reverse order, restore the water supply, and test.

For a leaking ceramic disc tap:

1. Isolate the water supply as above.
2. Remove the tap handle and locate the cartridge - it's typically a cylindrical unit secured by a retaining nut.
3. Photograph the cartridge before removing it, including any directional markings on the unit.
4. Take the old cartridge to a plumber's merchant or search the manufacturer's part number online to find an exact replacement.
5. Fit the new cartridge, reassemble, and restore the water supply.

One thing our engineers see regularly in Solihull homes is homeowners buying the wrong replacement part. Cartridges are not universal - a cartridge from a Bristan tap will not fit a Grohe or Hansgrohe unit, for example. If you're not certain what you have, photograph the existing tap and its markings before buying anything.

When You Need a Professional vs Sorting It Yourself

DIY tap repair is entirely reasonable in some situations. If the fault is a worn washer in an accessible compression tap, and you're comfortable working with basic tools and can isolate the water supply, there's no reason you can't tackle it yourself. A new washer costs pence, and the job rarely takes more than 30 minutes if you know what you're doing.

Call a plumber when:

• You can't identify which tap type you have or where exactly the fault lies.
• The valve seat is damaged - this needs regrinding with specialist equipment.
• The leak is from a tap that feeds a heating system or combination boiler, where interfering with the wrong valve could cause wider problems.
• You've attempted a repair and the dripping has got worse or spread to a different area.
• The tap is leaking at the pipe connections under the sink rather than from the spout - this is a separate problem requiring different skills.
• You have a high-end tap from a brand like Hansgrohe or Grohe and want to protect the warranty.

In West Midlands properties with older plumbing - particularly homes in parts of Solihull where the housing stock dates from the 1960s and 70s - our engineers commonly find that the pipes around the tap are corroded too. Attempting a DIY repair without noticing this can sometimes cause a pipe joint to fail when you restore the water pressure, turning a simple drip into a much bigger problem.

What to Expect from a Professional Tap Repair Visit

When a plumber visits to repair a leaking tap, the visit typically follows a consistent pattern. They'll isolate the water supply, diagnose the cause of the leak, source or fit the correct replacement part, and test the repair before leaving. Most standard tap repairs - replacing a washer, O-ring, or cartridge - take between 30 minutes and an hour once a plumber is on-site.

On pricing, expect to pay a call-out fee plus labour. In the West Midlands, a call-out typically costs between 50 and 90 pounds, with the full repair - including parts - commonly coming in between 80 and 160 pounds for a standard tap. If the valve seat needs regrinding, or a tap unit needs full replacement, costs can rise to between 150 and 300 pounds depending on the tap specification. Taps supplied by the homeowner are often fitted at the lower end of that range; supply-and-fit jobs cost more.

Our engineers working across Solihull carry common washers, O-rings, and a range of standard cartridges on the van, which means most routine repairs are completed in a single visit. For less common cartridges - particularly those from European designer brands - a part may need to be ordered, which can add a day or two to the repair timeline. If you log the tap make and model through the Voltrade GoFIX tool before your appointment, the engineer can arrive prepared with the most likely replacement part already on hand.

One thing worth asking when you book: whether the plumber offers a guarantee on the repair. Reputable engineers will commonly offer a 12-month guarantee on parts and labour for tap repairs, which gives you something to fall back on if the same component fails again.

Common Questions from Solihull Homeowners

How much water does a dripping tap actually waste?

More than most people expect. A tap dripping once per second commonly wastes around 30 to 40 litres per day - which adds up to over 10,000 litres across a year. For Solihull households on a water meter, that translates into a real and measurable increase on your bill. Beyond the cost, constant dripping puts ongoing stress on the fitting and can stain or erode the sink surface over time, leading to additional repair costs that could have been avoided.

Can I fix a leaking tap without turning off the mains water supply?

In most cases, no. You need to stop the water flow before dismantling any part of the tap. In modern homes there's commonly an isolation valve - a slotted valve on the supply pipe directly under the sink - that you can turn with a flat-head screwdriver without affecting the rest of the house. If there's no isolation valve, you'll need to turn off at the mains stopcock, typically found under the kitchen sink or where the supply pipe enters the property.

How do I know if I have a ceramic disc tap or a traditional washer tap?

The easiest way to tell is by how the tap operates. Ceramic disc taps typically turn through a quarter-turn from fully open to fully closed - they're designed to feel crisp and positive. Traditional compression taps need multiple full rotations - often two or more turns - to open and close completely. If you're still unsure, log what you're seeing through the Voltrade GoFIX tool before booking, and our engineers can advise on the likely fault before they arrive on-site.

Is it worth replacing the tap entirely rather than just repairing it?

Sometimes, yes. If your tap is more than 15 to 20 years old, the components are badly corroded, or you're already planning a kitchen or bathroom update, full replacement can make more sense than repeated repairs. A new tap from a reputable brand like Grohe, Bristan, or Hansgrohe typically costs between 60 and 250 pounds supplied, with fitting adding around 80 to 150 pounds in labour. A plumber can advise on whether repair or replacement is the more cost-effective option given the specific condition of your existing fitting.
