Working in Allerton
As well as Allerton itself (L18, L19 and L25), we survey in Hunts Cross, Garston and Halewood.
Being a smaller town does not change how we work in Allerton: free survey, written quote, one team. If your Allerton bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. If your Allerton water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
Most of Merseyside 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
- The WC connected to the soil stack, or a new branch where the WC is moving
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- A pressure test of new pipework before walls are closed in and floors go down
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
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 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.
