Working in Rhondda
We cover every part of Rhondda, including CF40, CF41 and CF43, and nearby Tonypandy (2.6 miles) and Aberdare (3.8 miles).
Homes in and around Rhondda vary, so we look at the floor, the walls and the water system before we price anything. If your Rhondda house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Rhondda loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Most of Mid Glamorgan is supplied with soft water. If that holds for your street in Rhondda, 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
- 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 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
Gravity or pumped waste
Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.
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.
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.
