Working in Kilwinning
We work right across Kilwinning — KA13 — and in neighbouring Irvine and Kilmarnock.
Being a smaller town does not change how we work in Kilwinning: free survey, written quote, one team. In Kilwinning flats, any change to the WC or wastes is planned with the title deeds and the flat below in mind. For Kilwinning homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
Supplies across most of Ayrshire 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
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
Decisions to make first
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.
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 Scotland
In Scotland, the Scottish Water Byelaws 2014 cover new water fittings, with the same 6-litre flush limit and backflow rules. Altering drainage may need a building warrant, so check before moving a WC or adding a new connection to the stack.
