In Cwmbran, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Cwmbran bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. Plumbing surveys in Cwmbran include a look at the existing pipework for lead, corrosion or poor support before we quote.
Water hardness varies across Gwent: some supplies are soft, others moderately hard or hard. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- A check of your hot water system, and the pressure and flow rate at the bathroom
Decisions to make first
Gravity or pumped waste
Gravity drainage is always the first choice. A shower waste pump or macerator solves a run that cannot fall, but adds noise, a power supply and servicing.
Hard water
In hard water areas, a scale reducer or water softener protects valves, shower heads and glass. Keep an unsoftened tap in the kitchen for drinking.
Rules that apply in Wales
Wales also uses the Water Supply (Water Fittings) Regulations 1999 and has its own Part H for drainage. The same rule on macerators applies: there must be a gravity-drained WC elsewhere in the home.
