Leaking Tap Repair Guide for Cranbrook Homes

Published July 2026 | Leaking Tap Repair

In the First 10 Minutes

A dripping tap feels minor until you work out how much water it's actually losing. Even a slow, steady drip can waste thousands of litres over a year - and if you're on a water meter, that waste shows up directly on your bill. Act quickly, even if it doesn't feel urgent.

Here's what to do immediately:

1. Find the isolation valve. It sits on the supply pipe directly beneath the sink or basin - a small inline fitting with a slot across it. Turn it 90 degrees with a flathead screwdriver until the slot runs perpendicular to the pipe. This cuts water to that tap only, leaving everything else in the house running normally.
2. If there's no isolation valve, use the main stopcock. Older Cranbrook properties - particularly Victorian terraces and pre-war semis common in the town - often lack individual isolation valves. Your main stopcock is typically under the kitchen sink, in a cupboard beneath the stairs, or near the front door. Turn it clockwise to close.
3. Put something under the tap. If you can't isolate immediately, place a bowl or folded towel beneath the drip to catch water and protect the cabinet below.
4. Don't just ignore it and go to bed. A tap left dripping overnight can cause water damage to the cabinet base, and in older properties, that can mean swollen chipboard or the early stages of mould.

Within the First Hour

Once the water is contained, take a proper look at what you're dealing with. Not all tap leaks are the same fault, and knowing which type you have will save time when you call a plumber.

Our engineers commonly see four types of tap leak:

1. Dripping from the spout - the most common. Usually a worn washer on older pillar taps, or a failed ceramic cartridge on modern mixers. Water drips even when the tap is fully off.
2. Leaking around the base of the spout - water seeps out around where the spout meets the body of the tap when it's running. Typically an O-ring failure.
3. Dripping from under the sink - could be a loose tap tail nut, a failing flexi-hose connection, or a cracked supply fitting. Less visible, often more damaging.
4. Leak from the handle area - water appears around the spindle when the tap is turned. This is typically gland packing failure, more common on older brass taps.

If you're not sure which category your leak falls into, the Voltrade GoFIX diagnostic tool walks you through a short set of questions about where the water is coming from, the type of tap, and how it behaves. It helps you describe the fault clearly to any plumber you call, which means they can bring the right parts and avoid a wasted visit.

While you're assessing the tap, open the cabinet underneath and check for signs of existing water damage - swollen board, damp patches, or a musty smell. Cranbrook's older housing stock can have wooden cabinet bases that absorb water quickly, and catching secondary damage early keeps repair costs manageable.

Same Day

This is the point to get a plumber booked. A leaking tap isn't usually a burst-pipe emergency, but it's also not something to leave unattended for days. A reliable local plumber in Cranbrook should be able to fit you in within 24 to 48 hours for a non-urgent drip repair.

When you call, have the following ready:

• The type of tap - pillar tap (two separate taps), monobloc mixer (single lever or knob), or bridge mixer
• The brand if you know it - Bristan, Grohe, Hansgrohe, and Ideal Standard are all common in Kent homes
• Where the water is coming from (spout, handle, base, or under the sink)
• Whether it's a kitchen, bathroom, or outside tap
• Roughly how old the tap is, if you know

Understanding likely costs helps you avoid surprises. Plumbers in Kent typically charge between 50 and 90 pounds per hour. For most tap repairs, expect to pay in these ranges:

• Washer replacement on a pillar tap: typically 80 to 140 pounds all in
• Ceramic cartridge replacement on a mixer: typically 100 to 190 pounds all in
• O-ring or gland packing repair: typically 80 to 150 pounds all in
• Full tap replacement (supply and fit, customer's own tap): typically 130 to 220 pounds labour
• Full tap replacement (including a quality tap): typically 200 to 380 pounds depending on the fitting chosen

Be wary of quotes that come in significantly below these ranges. Some tradespeople undercharge on labour and compensate through inflated parts pricing, which isn't always obvious until you see the invoice.

It's also worth thinking about whether your tap is worth repairing at all. If it's more than 15 to 20 years old, heavily scaled, or made by a manufacturer that's no longer trading (making cartridges hard to source), replacement can be the more economical choice in the long run. Any reputable Cranbrook plumber should be upfront about this before they start work.

The Repair Visit

Here's what a professional tap repair looks like in practice, so you know what to expect on the day.

The plumber will typically want to see the tap running before they isolate anything. This lets them confirm the fault themselves rather than working from your description alone. They'll also check the water pressure, which affects both the diagnosis and how quickly certain components wear out.

For a standard dripping pillar tap, the process runs roughly like this:

1. Isolate the water supply at the valve or stopcock
2. Remove the tap handle - usually held by a screw under a decorative cap
3. Unscrew and lift out the tap headgear
4. Replace the washer or jumper valve assembly
5. Reassemble, turn the water back on, and test under pressure

For a mixer tap with a ceramic cartridge, it's a similar process but the cartridge needs to match the exact tap model. This is where brand matters - a Grohe cartridge is not interchangeable with a Bristan cartridge, even if the taps look similar. A prepared plumber will bring common sizes, but less common models may require ordering, which can mean a return visit.

Most straightforward repairs are completed within an hour. Full tap replacements typically take one and a half to two and a half hours, including time to isolate, remove the old fitting, connect the new one, and test everything properly.

Before the plumber arrives, clear out the cabinet beneath the sink completely. Cleaning products, bins, and stored items all get in the way. Make sure there's also reasonable access to the area around the basin in bathrooms - it's difficult to work hunched over a toilet with no room to manoeuvre.

The Following Week

A tap repair isn't just done when the plumber leaves. Spend a few minutes over the next week checking that everything has settled properly.

Run through this short checklist a day or two after the repair:

• Turn the tap on fully in both hot and cold, then off, and check for any residual drip from the spout
• Open the cabinet below and look for any new damp patches around the supply connections
• Check that the tap handle feels solid with no wobble or looseness - a loose handle after reassembly can work its way back open
• If the flow seems reduced after the repair, check the aerator - the small mesh filter in the spout tip. Disturbing old pipes during a repair can knock loose debris that partially blocks it. Unscrew it, rinse under running water, and replace

Ask for a written receipt that specifies what parts were fitted and what guarantee applies. Most reputable plumbers will offer at least 12 months on both labour and parts they supply themselves. Keep this with your property paperwork - it matters if the same issue recurs.

Long Term

A leaking tap is usually a symptom of wear rather than a freak occurrence. A few habits and small investments can significantly reduce how often this happens.

Annual checks take ten minutes. Once a year, work through every tap in the house - turn each one on and off, and open the cabinet below to check for any damp. Catching a slow drip before it becomes a waterfall under your sink is always easier and cheaper.

Water pressure is often the underlying cause. High mains pressure accelerates wear on washers, O-rings, and cartridges considerably. In Kent, mains pressure varies across the county depending on local infrastructure. If you're finding that washers fail every year or two, it's worth asking your plumber to check your incoming pressure with a gauge. Anything consistently above 3 bar can be managed with a pressure reducing valve fitted at the mains - typically 150 to 250 pounds to supply and fit, but it extends the life of every fitting in the house.

Fit isolation valves if you don't have them. If your Cranbrook property doesn't have an isolation valve under every tap, ask your plumber to add them next time they're on site. They typically cost 15 to 30 pounds each to supply and fit, and they make future maintenance far less disruptive.

Choose quality when replacing. If taps do need replacing, mid-range fittings from brands like Bristan, Grohe, or Ideal Standard typically last 10 to 20 years with minimal maintenance beyond the occasional cartridge. Budget taps from DIY sheds are often harder to source parts for and have shorter lifespans - what looks like a saving upfront frequently costs more over time.

Timeline Questions

How long does a leaking tap repair take in Cranbrook?

Most tap repairs are completed within one to two hours from the plumber arriving. A basic washer replacement on a pillar tap is often done in under an hour. Ceramic cartridge replacements on mixer taps take a little longer, particularly if the plumber needs to source a cartridge specific to a less common brand. Full tap replacements typically take between one and a half and two and a half hours, including isolating the supply, removing the old fitting, and testing the new one under pressure.

Can I repair a leaking tap myself without a plumber?

On older pillar taps, replacing a washer is within reach for a confident DIYer - isolate the water, remove the headgear, swap the washer, reassemble. It requires basic tools and a replacement washer that costs pennies. Modern ceramic cartridge mixers are considerably more involved, and getting the wrong cartridge or reassembling incorrectly can create a worse leak than you started with. If you're uncertain at any point, the cost of a plumber is almost always less than the cost of water damage from a repair that hasn't held.

What causes taps to keep leaking in older Kent properties?

The most common cause is gradual wear on internal components - washers, O-rings, and cartridges all degrade with regular use over years. In parts of Kent with harder water, limescale build-up inside the tap body can accelerate this by preventing parts from seating correctly and by creating abrasive surfaces that wear components faster. Properties in Cranbrook with original fittings from the 1980s or earlier are also prone to gland packing failure, where the seal around the tap spindle breaks down with age.

Is a leaking tap covered by home insurance?

The repair to the tap itself is typically not covered - that's considered routine maintenance and falls to the homeowner. However, if the leak has caused damage to flooring, cabinetry, or the property below (relevant in flats or maisonettes), your buildings or contents insurance may cover that consequential damage. Document any damage with photographs before any work starts, and check your policy wording carefully. Some policies require you to have taken reasonable steps to prevent further damage, so acting quickly on isolation matters.
