Common tap problems — and the hard-water link
A tap should be diagnosed by the fault location and supply conditions. Water at the outlet may point to a washer, cartridge or damaged tap seat; leakage at the spindle, base, flexible tails or service valves has different causes. For weak flow, the plumber checks the aerator, local isolator, cartridge and branch pressure, then compares other outlets to decide whether the issue is local or property-wide. Thames Water confirms the regional supply is hard, so scale can affect aerators and cartridges, but wear, debris, damaged seats, seals and pressure imbalance remain separate possibilities.1
Fitting a new tap or mixer
Before fitting a tap or mixer, the plumber checks the manufacturer’s minimum operating pressure against the actual hot and cold supplies; a mains cold feed and tank-fed hot supply can give a mixer an obvious imbalance. They also check tap holes, tail connections, seized headgear or body threads, tap-seat condition and access to monobloc fixings beneath deep sinks or stone worktops. If a local valve does not isolate—or a converted house shares a stop valve—the swap may need a coordinated shutdown through the landlord or managing agent. An obsolete proprietary cartridge may require identification and ordering, and matching period tapware depends on parts availability rather than being guaranteed.
Water regulations for taps
Taps are covered by the Water Supply (Water Fittings) Regulations 1999, including the requirement for a conveniently situated tap supplying wholesome drinking water.2 Backflow protection depends on the outlet and intended use. Water Regs UK identifies hose-union taps as typically fluid category 3 or 5: a double check valve may suit an ordinary category 3 garden use, but it is not sufficient for category 5 uses, which require category-appropriate protection such as a suitable air-gap arrangement.4 The plumber should assess the intended use and, where necessary, confirm the arrangement with the water undertaker.
Find a verified plumber for taps by district
- Tooting Bec & Furzedown (SW17) — houses where the plumber compares hot and cold pressure, checks whether a supply is tank-fed and confirms that the selected mixer meets its minimum-pressure specification.
- Tooting Broadway (SW17) — flats and conversions where a failed local valve may mean the tap cannot be isolated until a communal cupboard is opened and the managing agent authorises a shutdown.
- Upper Tooting (SW17) — terraces and conversions where a shared incoming supply or mixed pressure system should be traced before dismantling a mixer.
- Gardens, garages and garden rooms — external feeds need accessible frost isolation, suitable pipe protection and backflow protection matched to the hose or equipment use.

| Fit isolation valves / outside tap | £90–£220 |
Tooting sits inside the London-wide ULEZ (£12.50 daily for non-compliant vehicles), which TfL expanded across all boroughs on 29 August 2023, but outside the central Congestion Charge zone.3
Frequently asked questions
On a mixer or quarter-turn tap the sealing component may be a cartridge rather than a washer. Repeated failure can also indicate a damaged seat, debris, pressure imbalance or a leak at the body, tails or service valve. The actual fault location should be confirmed before another washer is fitted.
Not always. Check the tap’s minimum operating pressure against the hot and cold supplies, the tap-hole pattern, available fixing access and the pipe connections. A low-pressure gravity-fed hot supply may not perform well with a tap designed for higher pressure.
An outside hose-union tap needs backflow protection matched to the assessed use. A double check valve may be suitable for ordinary fluid-category-3 garden use, but category-5 uses require higher protection; one arrangement is not universally compliant.4
Check whether the restriction is at one tap, one branch or the whole property. A blocked aerator, partly closed isolator, worn cartridge, debris, pressure imbalance or scale can all reduce flow; the sequence of checks identifies which.
Repair is sensible where the body, seat, threads and fixings are sound and a compatible part is available. Replacement may be more reliable where the body is damaged, access is poor or a proprietary cartridge is obsolete; an exact first-visit repair cannot be promised without identifying the part.

Why verified plumbers — not a general directory
Even a small tap job means someone working on your water supply and fittings. Whether they’re insured and competent — and, for anything affecting drinking water, aware of the regulations — is worth knowing up front.
Every listing is checked before going live and re-verified annually: we confirm the business is legitimately trading, verify the named contact, check evidence of public liability insurance and confirm SW17 coverage. For water work, WaterSafe is an optional approved-contractor assurance check; where gas work is involved, Gas Safe registration is mandatory.
Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. No customer middleman fee: enquiries go directly to the plumber.
