Working in Gorseinon
We work right across Gorseinon — SA4 — and in neighbouring Llanelli and Swansea.
Gorseinon gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Gorseinon home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. If your Gorseinon bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Water across much of West Glamorgan is soft. 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
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- The WC connected to the soil stack, or a new branch where the WC is moving
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.
Concealed or exposed valves
Concealed shower valves look neater but need an access route for servicing. Exposed bar valves are easier to reach and replace.
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.
