Working in Welwyn Garden City
We work right across Welwyn Garden City — AL7 and AL8 — and in neighbouring Hatfield and Hertford.
In Welwyn Garden City, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Welwyn Garden City water is hard, a tap with a removable aerator and a smooth one-piece basin top are easier to keep clean. Wall-hung vanities in Welwyn Garden City homes are fixed to suit what the wall is built from, which we check at the survey.
Water across much of Hertfordshire is very hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A new tap, trap and the correct slotted or unslotted waste for the basin
- Testing for leaks and checking the trap holds its seal
- Moving the waste and supply positions where the new unit needs them higher, lower or to one side
- Patching or re-tiling the wall where the old basin left gaps
Decisions to make first
Width
Compact units around 400 mm wide suit cloakrooms; family bathrooms often take 600 to 800 mm for one basin and 1200 mm or more for two.
Basin type
An inset or semi-recessed basin, a one-piece moulded top, or a countertop basin on a worktop. Countertop basins need a tall tap or a wall-mounted one.
Rules that apply in England
In England, the tap and supply pipework come under the Water Supply (Water Fittings) Regulations 1999. A new waste connection to the soil stack can be Part H work, and adding a light to the unit or above it is notifiable under Part P.
