Working in Llanelli
As well as Llanelli itself (SA15), we survey in Gorseinon, Swansea and Ammanford.
In Llanelli, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If the shower in your Llanelli home swings between hot and cold, a thermostatic valve is usually the fix. If you want a shower in your Llanelli home that works when the boiler is off, an electric shower is worth considering, as long as the consumer unit can take the circuit.
Most of Dyfed is supplied with soft water. If that holds for your street in Llanelli, 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.
What the job includes
- Electrical connection by a qualified electrician, tested and certified
- A bath screen, tray or enclosure where the shower is new
- Supply and fitting of the shower valve or unit, riser rail, handset or fixed head
- Removal of the old shower, a full-flow test and a handover on isolating and descaling it
Decisions to make first
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.
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.
Rules that apply in Wales
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.
