Working in Portsmouth
In Portsmouth we cover PO1, PO2, PO3 and 3 more postcode districts; we also cover Gosport, 1.7 miles away, and South Hayling.
In a city the size of Portsmouth, parking and access for a skip are worth sorting before the start date — we will ask at the survey. In Portsmouth flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Portsmouth water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
Water across much of Hampshire is hard. 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
- A pressure test of new pipework before walls are closed in and floors go down
- A check of your hot water system, and the pressure and flow rate at the bathroom
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- The WC connected to the soil stack, or a new branch where the WC is moving
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.
