Working in Lisburn
We work right across Lisburn — BT17, BT26, BT27 and 1 more postcode districts — and in neighbouring Belfast and Castlereagh.
In a city the size of Lisburn, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If your Lisburn home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. If your Lisburn water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
Water across much of County Antrim is 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
- A pressure test of new pipework before walls are closed in and floors go down
- The WC connected to the soil stack, or a new branch where the WC is moving
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
Decisions to make first
Gravity or pumped waste
Gravity drainage is always the first choice. A shower waste pump or macerator solves a run that cannot fall, but adds noise, a power supply and servicing.
Concealed or exposed valves
Concealed shower valves look neater but need an access route for servicing. Exposed bar valves are easier to reach and replace.
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.
