Working in Ammanford
We work right across Ammanford — SA18 — and in neighbouring Clydach and Gorseinon.
Being a smaller town does not change how we work in Ammanford: free survey, written quote, one team. If your Ammanford home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. If your Ammanford bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Most of Dyfed 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
- A pressure test of new pipework before walls are closed in and floors go down
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- 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.
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.
