Working in Purley
In Purley we cover CR2, CR5 and CR8; we also cover Coulsdon, 1.7 miles away, and South Croydon.
London homes in Purley often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Purley bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. If your Purley water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
Most of Greater London 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
- 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
- The WC connected to the soil stack, or a new branch where the WC is moving
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
Decisions to make first
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.
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.
