Working in Ammanford
In Ammanford we cover SA18; we also cover Clydach, 8.5 miles away, and Gorseinon.
Ammanford gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Ammanford house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Ammanford home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Most of Dyfed is supplied with soft water. If that holds for your street in Ammanford, 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 shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A survey of the headroom across the room, with the usable height marked at each fitting position
- A check of the floor joists where a bath or large shower tray will sit
Decisions to make first
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
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.
