Kitchen plumbing in Welwyn Garden City

Is kitchen plumbing right for your Welwyn Garden City kitchen?

Plenty of Welwyn Garden City kitchens still have the sink where it was put decades ago, and moving it under the window or into an island is a common reason to call a plumber.

Landlords in Hertfordshire often ask for every appliance to have its own isolation valve, so a tenant can stop a leak quickly without turning off the whole property. Kitchens in every part of Welwyn Garden City are covered, and the survey visit is free wherever you are in Hertfordshire.

What does the job involve?

The exact scope is agreed after the survey, but a typical job in Welwyn Garden City covers:

Hot and cold supplies run to the new sink position
A survey of the stopcock, supply pipes, waste route and drain connection
Dishwasher and washing machine supplies, with waste connections through suitable traps
Waste pipes laid to a steady fall, with an access point for clearing blockages
Radiators moved or replaced so they clear the new units
Isolation valves on each tap and appliance feed for quick shut-off

Local homes and their kitchens

Typical homes in this part of Hertfordshire include 1930s semis, post-war new town houses, Victorian terraces and new-build estates. Stevenage and Hemel Hempstead new-town houses often have a small galley, while 1930s semis tend to have a narrow kitchen beside the dining room.

Commuter-town streets often have tight parking, and estate houses with shared parking courts can mean carrying units some distance to the front door. Hertfordshire's water is very hard, mostly drawn from chalk, so limescale on taps and boiling water taps is common and a softener or filter is worth considering.

Regulations for kitchen work in Welwyn Garden City

In England, kitchen pipework and fittings must meet the Water Supply (Water Fittings) Regulations 1999, which cover suitable materials, backflow protection and preventing waste or contamination of the supply. Connecting a sink to an existing waste or stack is routine, but a new connection to an underground drain, or a change to how waste water is discharged, involves building control. Gas pipework to a hob or cooker is separate work for a Gas Safe registered engineer.

A kitchen fit needs no planning permission, but listed buildings and conservation areas, including parts of St Albans and Welwyn Garden City, may need consent for external vents.

Planning ahead

If your house in Hertfordshire has a solid floor, ask at the survey where a waste could run before you settle on an island sink.
Ask for an access point on the waste near the sink, so a future blockage can be cleared without taking a unit out.
Measure the cupboard under your sink before buying a boiling water tap for your Welwyn Garden City kitchen, as the tank and pipework need clear space.
Check your water pressure suits the tap you want, particularly a boiling water tap or a tall spray tap; the tap's instructions give its minimum.

Questions about kitchen plumbing in Welwyn Garden City

Which parts of Welwyn Garden City do you work in?

All of them. Our Hertfordshire coverage takes in the whole of Welwyn Garden City, including the AL8 postcode district, as well as surrounding towns such as Hatfield. If you are unsure, send us your postcode.

When does kitchen plumbing need building control?

Most kitchen plumbing does not. Replacing a sink, adding appliance connections and rerouting supply pipes inside the kitchen are routine. A new connection to an underground drain, or a change in how waste water is discharged, needs building control approval in England, Wales and Northern Ireland, or a building warrant in Scotland. Every fitting must also meet the water fittings rules for your nation.

What plumbing does a boiling water tap need?

A boiling water tap needs a cold supply to a tank under the sink, usually through a filter, plus an electrical socket or spur for the tank. Some models also take hot and cold feeds for the mixer side. The tank uses cupboard space, so the sink unit is planned around it, and the tap's minimum water pressure is checked against your supply.

Can a kitchen sink be moved to a different wall?

Yes, usually. The supplies are the easy part; the waste decides it, because it needs a steady fall all the way to the stack or drain. On a suspended timber floor the pipe can often run between the joists, while on solid concrete a channel may need to be cut and filled. Where a fall cannot be achieved, a pumped waste is sometimes considered.
