Working in Llanelli
We cover every part of Llanelli, including SA15, and nearby Gorseinon (5.2 miles) and Swansea (10.3 miles).
In Llanelli, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Llanelli house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Llanelli loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself.
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
- A check of your hot-water system and of the pressure and flow you actually get at loft level
- A survey of the headroom across the room, with the usable height marked at each fitting position
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
Decisions to make first
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
Getting the water pressure
A pumped shower suits a gravity system with a cold tank; an electric shower heats cold mains water at the point of use; a combi or unvented cylinder gives mains pressure throughout.
Rules that apply in Wales
Wales applies its own Part P, with a wider notifiable list than England, and its own Part F with similar extract rates. Part H covers the new drainage route down from the loft.
