Working in Bangor
We work right across Bangor — LL57 and LL59 — and in neighbouring Caernarfon and Llandudno.
Being a smaller town does not change how we work in Bangor: free survey, written quote, one team. If your Bangor water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads. For Bangor homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
Water across much of Gwynedd 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
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- A check of your hot water system, and the pressure and flow rate at the bathroom
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- The WC connected to the soil stack, or a new branch where the WC is moving
Decisions to make first
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.
Hard water
In hard water areas, a scale reducer or water softener protects valves, shower heads and glass. Keep an unsoftened tap in the kitchen for drinking.
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.
