Working in Castlereagh
As well as Castlereagh itself (BT5, BT6 and BT7), we survey in Belfast, Newtownabbey and Lisburn.
In Castlereagh, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Landlords in Castlereagh can have a worn basin replaced with a vanity unit in half a day to a day. If you have bought a vanity unit for your Castlereagh bathroom, fit-only installation covers connecting the tap and waste and testing for leaks.
Most of County Antrim is supplied with soft water. 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
- A new tap, trap and the correct slotted or unslotted waste for the basin
- Isolation valves on the hot and cold supplies, so the tap can be changed later without draining the system
- Patching or re-tiling the wall where the old basin left gaps
- Testing for leaks and checking the trap holds its seal
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.
Wall-hung or floor-standing
Wall-hung units leave the floor clear and are easy to clean under, but need a strong wall. Floor-standing units hold more and suit weak or uneven walls.
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.
