Which towns do we cover in Gwynedd?
Most of Gwynedd is supplied with soft water. If that holds for your street in Bangor, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier. We test pressure and flow at Bangor surveys before recommending a shower, so you know how it will perform before you buy.
What the job includes
- Removal of the old shower, a full-flow test and a handover on isolating and descaling it
- For an electric shower, a check of the consumer unit and whether a new dedicated circuit is needed
- Electrical connection by a qualified electrician, tested and certified
- A bath screen, tray or enclosure where the shower is new
- Tiling or re-tiling around the shower, with tanking behind new tiles in the wet area
- New pipework and isolation valves, plus a pump only where the system is gravity-fed from a cold tank
Decisions to make first
Power shower
A mixer with a built-in pump, for tank-fed systems only. It lifts a weak gravity shower but must never be connected to the mains.
Electric shower
Heats cold mains water as it flows, so it works without stored hot water. Higher kW units give more flow; 8.5 to 10.5 kW models need a dedicated circuit, often 40 to 45 amps.
Thermostatic mixer
Blends hot and cold from your system and holds the temperature steady when someone runs a tap. The usual choice with a combi or an unvented cylinder.
Exposed or concealed
An exposed bar valve fixes onto the tiles and is easy to service. A concealed valve sits in the wall for a cleaner look but needs careful setting-out and a plan for access.
Rules that apply in Wales
The water fittings regulations in each nation do not allow a pump to be connected directly to the mains supply; shower pumps are for gravity systems with a cold tank only. The shower must also be protected against water flowing back into the supply. Electrics must meet BS 7671, with 30 mA RCD protection and at least IPX4 fittings in zone 1, or IPX5 where water jets are used.
In Wales, a new circuit for an electric shower is notifiable under the Welsh Part P, which covers more work than the English version. An unvented cylinder must be fitted by a G3-qualified installer.
