Working in Prestatyn
As well as Prestatyn itself (LL19), we survey in Rhyl, Flint and Colwyn Bay.
Being a smaller town does not change how we work in Prestatyn: free survey, written quote, one team. If your Prestatyn water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads. If your Prestatyn bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
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
- 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
- The WC connected to the soil stack, or a new branch where the WC is moving
- A pressure test of new pipework before walls are closed in and floors go down
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.
Shower supply
Combi boilers and unvented cylinders give mains pressure. A gravity system with a cold tank may need a pump, but a pump must never be connected to the mains.
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.
