Common tap faults in Southwark properties
Tap faults typically fall into one of these categories:
Dripping or leaking tap
- Worn rubber washer — the most common cause in traditional pillar taps
- Failed ceramic cartridge — common in modern mixer taps and quarter-turn taps
- Damaged O-ring seal — typically causes leaking at the base of the tap body or spout
- Worn valve seat — prevents the washer from creating a watertight seal
Tap leaking underneath the sink
- Loose or degraded compression fittings on the tap connector
- Failed flexible hose connection
- Corroded or cracked tap tail
Stiff or seized tap
- Limescale build-up on internal ceramic disc components — common in hard water areas
- Corrosion on the spindle from age and moisture
Low water pressure at a single tap
- Blocked aerator — the mesh filter at the tap outlet — commonly caused by limescale
- Partially closed isolation valve below the tap
Tap repair Southwark — why prompt repair matters
Thames Water confirms that dripping taps are a common form of domestic leak.²
Thames Water advises that leaks on your property should be repaired promptly to avoid water waste and potential charges. In some cases, water companies have powers to address ongoing leaks under the Water Industry Act 1991.²
If you do not have isolation valves fitted under your kitchen or bathroom taps, we recommend asking your plumber to fit them during a tap repair Southwark visit — this is now industry standard practice and prevents the need to isolate the whole property during any future work.
Hard water and tap faults in Southwark SE London
Southwark sits in Thames Water’s hard water area. Thames Water confirms hard water can leave behind a chalky residue called limescale on household fittings and appliances.¹
In Southwark properties, limescale commonly affects:
- Ceramic disc tap cartridges — causing stiffness and failure over time
- Tap aerators — restricting flow at the outlet
- Flexible tap connectors — accelerating corrosion at fittings
We recommend asking your plumber to descale or replace the aerator as part of any kitchen tap repair Southwark job — it is a quick, low-cost step that can restore full flow without replacing the tap.
If you are installing a water softener, Thames Water advises that a separate drinking water tap should be installed, and that the plumbing and softening unit should be inspected regularly by an approved plumber.¹
New tap installation in Southwark — what to consider
Installing a new tap in Southwark is typically a straightforward job, but time required depends on access and pipework.
Factors that affect the scope and cost include:
- Tap type — pillar taps, mixer taps, monobloc kitchen mixers and wall-mounted taps each have different installation requirements
- Access to isolation valves — if the tap lacks an accessible isolation valve below it, the water supply may need to be isolated at the stopcock during installation
- Pipework compatibility — replacing a pillar tap with a mixer tap may require pipework adaptation
- Outdoor tap installation — requires a connection to the cold supply and should include appropriate backflow prevention (such as a non-return valve) to comply with Water Fittings Regulations,³ as well as consideration of frost protection
- Electronic or sensor taps — increasingly common in purpose-built SE1 flats and modern conversions — require a plumber experienced with solenoid valves, not just standard cartridge or washer repairs
The Water Supply (Water Fittings) Regulations 1999 require water fittings to be of appropriate quality and standard, and to be installed in a workmanlike manner.³ A competent plumber should ensure the installation meets these requirements.

Frequently asked questions — Tap Repair & Installation Southwark
Yes. Thames Water states that leaks on a property, including dripping taps, must be arranged for repair within four weeks of identification.² Prompt repair also prevents water waste and rising bills if you are on a meter.
In traditional pillar taps with rubber washers, a washer replacement is a manageable DIY job if you can isolate the water supply. Modern mixer taps with ceramic cartridges are more complex — cartridge replacement is better left to a plumber to avoid damaging the tap body.
If you are unsure of the tap type, we recommend calling a plumber to diagnose first.
In Southwark’s hard water area, ceramic disc cartridges commonly seize due to limescale build-up over time.¹ A plumber can remove, clean or replace the cartridge. This is often more cost-effective than replacing the entire tap.
Southwark Council is responsible for internal pipes, valves and tap fittings in council-rented properties.⁴ Report a repair via Southwark Council’s repairs portal or call 0800 952 4444.
