Working in Welshpool
We cover every part of Welshpool, including SY21, and nearby Newtown (11.8 miles) and Brecon (50.4 miles).
Welshpool gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For Welshpool homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve. In Welshpool flats, any change to the WC or wastes is planned with the lease and the flat below in mind.
Most of Powys is supplied with soft water. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- A pressure test of new pipework before walls are closed in and floors go down
- The WC connected to the soil stack, or a new branch where the WC is moving
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
Decisions to make first
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.
Copper or plastic
Copper is rigid and suits pipes on show or near the boiler. Plastic is quicker under floors and inside walls, and long runs need fewer joints.
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.
