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. We check the duct route at Pontypridd surveys, because a short, straight run to outside matters more than the fan's headline figure. In Pontypridd flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Supplies across most of Mid Glamorgan are soft. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A backdraught shutter and external grille, so cold air does not blow back in
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
Decisions to make first
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
Rules that apply in Wales
Wales has its own Part F with similar extract rates, and its own Part P, under which new fan wiring in a bathroom is notifiable.
