What kitchen plumbing covers

The kitchen packs a lot of plumbing into a small space, and the rules exist to keep your drinking water clean and your waste flowing:

The drinking-water tap. Under Schedule 2 paragraph 27 of the Water Supply (Water Fittings) Regulations 1999, a dwelling must have a conveniently situated tap supplying wholesome drinking water. It may be supplied from a supply pipe, a qualifying pump-delivery pipe, or a distributing pipe from a cistern storing wholesome water; a direct, unsoftened mains-fed kitchen cold tap is the normal recommended arrangement where practicable, not a universal statutory requirement.¹
Sinks, taps and fittings. Taps and fittings must meet the water regulations; a mixer or pull-out spray that could reach into the bowl needs the right backflow protection. Adding isolation valves under the sink turns every future repair from a whole-house shut-off into a two-minute job.
Wastes and traps. A kitchen sink needs a trap holding a water seal, plus the correct fall and configuration on the waste; get it wrong and you get smells, slow draining, gurgling or dishwasher discharge backing into the sink. Diagnosis should start at the trap, then test the appliance connection and branch waste, check fall and layout, and investigate the downstream or shared stack if several outlets are affected. Appliance wastes tie in via a suitable trap spigot or trapped standpipe.
Appliance connections. Dishwashers and washing machines commonly present a fluid-category-3 backflow risk. The plumber should verify protection suitable for the appliance and installation — normally a compliant double check valve or another no-less-effective category-3 arrangement — unless the product approval and manufacturer’s instructions expressly confirm suitable integral protection.¹
Boiling-water taps and filters. Where one is specified, it needs the correct supply, a suitable tank or heater location and any filter required by the manufacturer — a proper installation rather than an assumed DIY tee.

Refit or relocation? Moving the sink to a new position with a new waste run into the drainage is altered drainage. New or materially altered drainage may require Building Control involvement under the Building Regulations, with Approved Document H providing the relevant technical guidance; reusing the existing waste generally does not involve the same alteration.²

Hard water, fat and Putney’s kitchens

Two forces dominate kitchen plumbing in Putney: what the water does to the fittings, and what goes down the sink.

Hard water everywhere. Thames Water classifies all its supply as hard,³ so scale can affect kitchen taps, spray heads, boiling-water-tap filters and appliance valves. If an ion-exchange softener is fitted, an unsoftened outlet for drinking is normally retained where practicable: the Drinking Water Inspectorate explains that this form of softening replaces calcium and magnesium with sodium.⁴ The final arrangement must still supply wholesome drinking water.

Fat is the enemy of the kitchen waste. Thames Water is clear that fats, oils and food scraps that set solid are a leading cause of blockages — sewers are built for wastewater, human waste and toilet paper, not the contents of a roasting tin.⁵ Cooling, disposal habits and a poor waste layout — including a wrong trap, inadequate fall or a long shallow run — are the clearer causes, which is why scraping plates into the bin beats rinsing fat into the sink.

The stock sets the layout. Managed riverside or town-centre flats may have integrated kitchens, concealed connections and communal isolation points; the block may require an approved contractor, an isolation booking or evidence of insurance. For a flat above a Putney High Street business, access to a stack or isolation point may involve the residential freeholder and the commercial occupier. Older conversions or rear extensions may have limited waste points or long, shallow runs that restrict where a sink or dishwasher can move. An integrated-dishwasher leak may remain hidden behind a plinth, so the plumber should gain access, test under operating pressure and complete a test cycle before cabinet panels are refitted. Council and social tenants should route kitchen repairs to Wandsworth Council, which manages its own stock.⁶

Find a verified plumber by Putney district

Postcode coverage varies by listing — confirm yours when you call.

Putney Embankment · Lower Richmond Road · riverside (SW15) — managed flats may have integrated kitchens, concealed connections or communal isolation; confirm access rules, insurance evidence and responsibility before work.

Putney High Street · town centre (SW15) — in a flat above a shop, a stack or isolation point may require coordination with both the residential freeholder and commercial occupier.

East Putney · West Putney (SW15) — conversions and rear extensions may have limited waste points or long, shallow runs, so a refit may require the waste route to be tested and redesigned.

Putney Hill · West Hill (SW15/SW18) — in mansion blocks, responsibility and permission for communal supplies or stacks should be confirmed before kitchen work proceeds.

Putney Heath · Putney Vale (SW15) — in the mixed local stock, hard-water scale is one possible cause of sticking taps, spray heads or appliance valves and should be confirmed on inspection.

Frequently asked questions

The regulations require at least one conveniently situated tap supplying wholesome drinking water. A direct, unsoftened mains-fed kitchen cold tap is the normal recommended arrangement where practicable, but it is not the only permitted supply arrangement.

You can, but an unsoftened drinking and cooking outlet is normally retained where practicable. The Drinking Water Inspectorate notes that ion-exchange softening adds sodium; the final arrangement must still provide wholesome drinking water.

Usually fat or food scraps have set in the trap or waste. The plumber should inspect the trap, test the branch with the appliance disconnected, check fall and configuration, and investigate the downstream or shared stack if several outlets are affected. Scrape plates into the bin; Thames Water identifies fats, oils and food scraps as a leading blockage cause.

A new or materially altered waste or drainage run may require Building Control involvement; confirm the specific work with the relevant building control body. Reusing the existing waste may not require approval.

Yes — but the plumber should verify fluid-category-3 protection appropriate to the appliance and installation, normally a compliant double check valve or another accepted arrangement unless the approval and manufacturer’s instructions confirm suitable integral protection. For an integrated dishwasher, they should also inspect the valve and hoses, run a test cycle, confirm drainage and check for leaks under operating pressure before refitting the plinth.

Why verified plumbers — not a general directory

A kitchen packs supply, waste and appliances into a small space, which is where drinking-water rules, backflow and fat-clogged wastes all collide — so the credential that matters is a plumber who builds it to the regulations and checks the actual water, appliance and drainage conditions.

Every listing is checked before going live and re-verified annually: we confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, and we confirm the plumber covers Putney’s SW15 postcodes before a profile is approved. You can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register of approved plumbers.⁸ Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →.

We charge plumbers a flat monthly listing fee; there’s no pay-to-play ranking and no per-enquiry middleman fee — enquiries go directly to the plumber.
