Working in Dunstable
As well as Dunstable itself (LU6), we survey in Luton, Leighton Buzzard and Harpenden.
In Dunstable, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Dunstable bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. In Dunstable flats, any change to the WC or wastes is planned with the lease and the flat below in mind.
Most of Bedfordshire has very hard water. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- The WC connected to the soil stack, or a new branch where the WC is moving
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- A pressure test of new pipework before walls are closed in and floors go down
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 England
In England, the Water Supply (Water Fittings) Regulations 1999 apply. New drainage or a new connection to the soil stack can be building regulations work under Part H, and a macerator or pumped WC is acceptable only where there is also a WC on gravity drainage elsewhere in the home.
