Stop drips wasting money: fixing leaking taps and traps the right way

A steady drip is easy to ignore until you see it on your water bill or spot swelling inside a sink cabinet. Small leaks rarely stay small. They waste water, stain surfaces, and can quietly damage cupboards, flooring, and surrounding structures if left unresolved.

The good news is that many tap, seal, and trap faults are straightforward to diagnose and repair. With the right approach, you can stop the drip quickly and avoid a much bigger problem later. This guide explains the most common causes of leaks, when DIY is appropriate, when to call a professional, how long repairs typically take, and how to prevent future issues.

If you are in Norwich or across Norfolk and need prompt assistance, Dr Plumbing Solutions offers same-day and next-day repairs for leaking taps, traps, and pipework, with free consultations and transparent estimates before work begins.

Why taps and traps start leaking

Leaks usually develop from a handful of common issues:

• Worn washers or cartridges. Modern mixer taps typically use ceramic cartridges, while older taps rely on rubber or fibre washers. Over time, wear or limescale prevents a proper seal, causing persistent dripping.
• Perished O-rings and seals. O-rings around the tap spout or base can dry out or split, allowing water to collect around the fitting or run into cupboards.
• Loose or cracked connections. Flexible hoses, isolation valves, and compression fittings may loosen or deteriorate with age, creating slow leaks that often go unnoticed.
• Faulty waste traps. Bottle traps and P-traps use compression washers that can wear or deform. Plastic nuts can also crack if overtightened.
• High water pressure or water hammer. Excessive pressure places additional strain on seals and cartridges, shortening their lifespan and causing intermittent leaks.

When DIY is safe – and when to call a professional

Many small repairs are manageable for confident homeowners, provided the water supply can be safely isolated.

DIY may be suitable for:

• Replacing a worn tap washer or matching ceramic cartridge
• Swapping a damaged O-ring on a tap spout
• Replacing or resealing a plastic waste trap
• Applying fresh silicone around sinks or basins to prevent water ingress

However, contact a qualified plumber if you notice:

• Leaks from concealed pipework or inaccessible areas
• Swollen cabinetry, soft flooring, or staining that suggests hidden water damage
• Corroded isolation valves that will not shut off properly
• Repeated cartridge failures or pressure-related issues
• Any fault involving gas appliances or boilers, which should only be handled by a Gas Safe registered engineer

If the source of a leak is unclear, professional leak detection can often identify the problem without unnecessary disruption. Our Norwich water leak detection service helps pinpoint hidden issues quickly and accurately.

Basic steps for a safe repair

If you choose to tackle a simple leak yourself:

1. Turn off the local isolation valves or the main stopcock.
2. Open the tap to release remaining pressure.
3. Protect the surrounding area with towels or containers.
4. Photograph components before dismantling to aid reassembly.
5. Avoid overtightening plastic fittings.
6. Turn the water back on and carefully inspect every joint for leaks.
7. Check again after 30 minutes to ensure the repair remains watertight.

If anything feels uncertain, it is safer and often more cost-effective to seek professional advice.

How long do repairs usually take?

For an experienced plumber, many common repairs can be completed quickly:

• Tap washer replacement: approximately 20–40 minutes
• Ceramic cartridge replacement: around 30–60 minutes
• Trap resealing or replacement: typically 20–45 minutes
• Resealing around sinks or basins: approximately 45–90 minutes, plus curing time
• Minor under-sink pipe repairs: usually 30–60 minutes

Actual times depend on accessibility, condition of existing fittings, and availability of replacement parts.

Understanding repair costs

The final cost depends on the type of fitting, required parts, accessibility, and the complexity of the repair.

Simple washer replacements and straightforward trap adjustments are generally among the quickest and most affordable plumbing jobs, while seized cartridges, specialist tap models, or hidden pipework repairs may require additional labour or replacement components.

At Dr Plumbing Solutions, we provide free consultations and clear upfront estimates so you know exactly what to expect before work begins.

Hidden damage you should not ignore

Even a slow drip can waste significant amounts of water over time. More importantly, ongoing leaks often soak chipboard cabinets, timber flooring, and plasterboard long before visible damage appears.

Left untreated, moisture can lead to:

• Swollen or deteriorating kitchen units
• Damaged flooring and skirting boards
• Mould growth in concealed spaces
• Stained ceilings beneath upstairs bathrooms
• More expensive structural repairs

Addressing a minor leak promptly is almost always less costly than repairing water damage later.

Will plumber's tape stop a leak?

PTFE (plumber's) tape is designed to seal threaded metal connections during installation. It is not a universal solution for active leaks.

For example:

• A leaking ceramic cartridge requires replacement.
• A worn washer or O-ring needs to be changed.
• A faulty flexible hose or damaged compression fitting should be repaired or replaced properly.
• Wrapping PTFE tape around an existing leak rarely provides a lasting solution.

Using the correct replacement component is the safest and most reliable approach.

Frequently asked questions

How much does it cost to fix a dripping tap?

The cost depends on the type of tap and the parts required. Simple washer replacements are usually straightforward, while ceramic cartridge replacements or specialist fittings may involve additional labour and component costs.

Can I repair a leaking pipe myself?

Visible, accessible joints beneath sinks may sometimes be suitable for DIY repairs if you can safely isolate the water supply. Hidden pipework or anything involving soldered connections should generally be left to a qualified plumber.

Does PTFE tape fix leaks?

PTFE tape helps create a seal when assembling threaded joints but will not repair worn cartridges, damaged hoses, or failed compression fittings.

Should I repair or replace an old tap?

If the same tap repeatedly develops faults, replacement may offer better long-term value. Modern taps with readily available spare cartridges are often easier and less expensive to maintain.

Simple maintenance tips to prevent future leaks

• Operate isolation valves periodically to prevent seizure.
• Check around tap bases for moisture during routine cleaning.
• Avoid overtightening plastic waste fittings.
• Remove limescale from aerators and tap components regularly.
• Replace failing silicone seals before water penetrates surrounding surfaces.

When replacement is the smarter option

If leaks continue after repeated repairs, spare parts are no longer available, or fittings are heavily corroded, replacing the tap or trap may be the most economical long-term solution.

During your consultation, Dr Plumbing Solutions can explain both repair and replacement options so you can make an informed decision.
