Working in Portishead
As well as Portishead itself (BS20), we survey in Nailsea, Clevedon and Bishopsworth.
In Portishead, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If you want a shower in your Portishead home that works when the boiler is off, an electric shower is worth considering, as long as the consumer unit can take the circuit. For Portishead homes with a cold tank in the loft, we check the system before fitting anything, because a pump is only allowed on a gravity supply.
Most of Somerset has hard water. If your supply in Portishead is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- New pipework and isolation valves, plus a pump only where the system is gravity-fed from a cold tank
- Removal of the old shower, a full-flow test and a handover on isolating and descaling it
- Tiling or re-tiling around the shower, with tanking behind new tiles in the wet area
- A check of your hot-water system, water pressure and flow rate
Decisions to make first
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.
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.
Rules that apply in England
In England, an electric shower usually needs its own dedicated circuit, often 40 to 45 amps for an 8.5 to 10.5 kW unit, and a new circuit is notifiable under Part P. The Part G limit of 48 °C applies to a new bath in a new dwelling or one created by change of use, not to a shower, but a thermostatic valve gives similar protection. An unvented cylinder fitted to improve the shower must be installed by a G3-qualified installer.
