Working in Blackwood
We work right across Blackwood — NP12 — and in neighbouring Gelligaer and Risca.
Blackwood gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Plumbing surveys in Blackwood include a look at the existing pipework for lead, corrosion or poor support before we quote. For Blackwood homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
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
- A pressure test of new pipework before walls are closed in and floors go down
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
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.
Pipe routes
Drilling through the middle of joists, rather than notching the tops, keeps the floor strong. Routes are planned with the joist direction in mind.
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.
