Working in Pontypridd
In Pontypridd we cover CF37; we also cover Tonypandy, 5.1 miles away, and Caerphilly.
In Pontypridd, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Pontypridd 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. If your Pontypridd loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Supplies across most of Mid Glamorgan are soft. If that holds for your street in Pontypridd, 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
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
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.
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.
