Working in Grangemouth
We cover every part of Grangemouth, including FK3, and nearby Falkirk (2.5 miles) and Alloa (7.7 miles).
Being a smaller town does not change how we work in Grangemouth: free survey, written quote, one team. If your Grangemouth home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. If your Grangemouth water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
Most of the Forth Valley is supplied with soft water. 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
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- 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
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.
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 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.
