Which towns do we cover in Gwent?
Supplies across Gwent range from soft to hard depending on the source. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier. In Newport flats, any change to the WC or wastes is planned with the lease and the flat below in mind.
What the job includes
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- A check of your hot water system, and the pressure and flow rate at the bathroom
- 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
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- A pressure test of new pipework before walls are closed in and floors go down
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.
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.
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 Wales
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.
Wales also uses the Water Supply (Water Fittings) Regulations 1999 and has its own Part H for drainage. The same rule on macerators applies: there must be a gravity-drained WC elsewhere in the home.
