Working in Holyhead
We cover all of Holyhead, including LL65, and nearby Caernarfon and Bangor.
Being a smaller town does not change how we work in Holyhead: free survey, written quote, one team. If your Holyhead bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. For Holyhead homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
Supplies across most of Gwynedd are 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
- A pressure test of new pipework before walls are closed in and floors go down
- 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
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
Decisions to make first
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.
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.
