Which towns do we cover in County Down?
Most of County Down 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. For Bangor homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
What the job includes
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- A pressure test of new pipework before walls are closed in and floors go down
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
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.
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
New WCs, taps, showers and valves must meet the water fittings rules where you live: a maximum 6-litre flush for new WCs, backflow protection, and no pump connected directly to the mains supply, because shower pumps are only for gravity systems with a cold tank. Unvented hot-water cylinders must be installed by a G3-qualified installer, and any work on a gas boiler by a Gas Safe registered engineer.
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.
