Working in Larne
In Larne we cover BT40; we also cover Carrickfergus, 9.3 miles away, and Newtownabbey.
Larne gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Larne bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. For Larne homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
Supplies across most of County Antrim 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
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- A check of your hot water system, and the pressure and flow rate at the bathroom
- A pressure test of new pipework before walls are closed in and floors go down
Decisions to make first
Copper or plastic
Copper is rigid and suits pipes on show or near the boiler. Plastic is quicker under floors and inside walls, and long runs need fewer joints.
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.
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.
