Working in Croydon
As well as Croydon itself (CR0, CR2, CR5 and 5 more postcode districts), we survey in Mitcham, Purley and Streatham.
London homes in Croydon often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. In Croydon flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Croydon home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.
Supplies across most of Greater London are very 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
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- 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
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.
