Working in Coleraine
As well as Coleraine itself (BT51, BT52 and BT55), we survey in Limavady, Magherafelt and Derry.
Homes in and around Coleraine vary, so we look at the floor, the walls and the water system before we price anything. In Coleraine flats, any change to the WC or wastes is planned with the lease and the flat below in mind. Plumbing surveys in Coleraine include a look at the existing pipework for lead, corrosion or poor support before we quote.
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
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- The WC connected to the soil stack, or a new branch where the WC is moving
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- A check of your hot water system, and the pressure and flow rate at the bathroom
Decisions to make first
Hard water
In hard water areas, a scale reducer or water softener protects valves, shower heads and glass. Keep an unsoftened tap in the kitchen for drinking.
Shower supply
Combi boilers and unvented cylinders give mains pressure. A gravity system with a cold tank may need a pump, but a pump must never be connected to the mains.
Rules that apply in Northern Ireland
In Northern Ireland, the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 apply to new fittings. New drainage and connections are a matter for building control.
