Working in Colwyn Bay
In Colwyn Bay we cover LL28, LL29 and LL31; we also cover Llandudno, 4.8 miles away, and Rhyl.
Homes in and around Colwyn Bay vary, so we look at the floor, the walls and the water system before we price anything. Plumbing surveys in Colwyn Bay include a look at the existing pipework for lead, corrosion or poor support before we quote. If your Colwyn Bay home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.
Water across much of Clwyd is moderately hard. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- The WC connected to the soil stack, or a new branch where the WC is moving
- A check of your hot water system, and the pressure and flow rate at the bathroom
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
Decisions to make first
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.
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.
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.
