In a city the size of Belfast, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If your Belfast bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. Plumbing surveys in Belfast include a look at the existing pipework for lead, corrosion or poor support before we quote.
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
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- 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
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.
Pipe routes
Drilling through the middle of joists, rather than notching the tops, keeps the floor strong. Routes are planned with the joist direction in mind.
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.
