Working in Derry
In Derry we cover BT47 and BT48; we also cover Limavady, 14.7 miles away, and Coleraine.
In a city the size of Derry, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If you have bought a vanity unit for your Derry bathroom, fit-only installation covers connecting the tap and waste and testing for leaks. If your Derry water is hard, a tap with a removable aerator and a smooth one-piece basin top are easier to keep clean.
Supplies across most of County Londonderry are soft. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- A check that the wall can carry a wall-hung unit, with fixings to suit solid or stud walls
- Testing for leaks and checking the trap holds its seal
- Removal of the old basin and pedestal, or old vanity, and taking it away
Decisions to make first
Waste and overflow
A basin with an overflow takes a slotted waste; one without needs an unslotted waste, often a push-button 'click-clack' type.
Drawers or doors
Drawers keep things visible and reachable but lose some space to the trap. Doors give a deeper cupboard and cost less.
Rules that apply in Northern Ireland
In Northern Ireland, the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 cover the tap and supplies. A basin swap does not need building control approval.
