Working in Archway
As well as Archway itself (N6, N19 and NW5), we survey in Islington, Tottenham and Walthamstow.
London homes in Archway often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. In Archway flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Archway home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.
Water across much of Greater London is 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
- A pressure test of new pipework before walls are closed in and floors go down
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- A check of your hot water system, and the pressure and flow rate at the bathroom
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.
Copper or plastic
Copper is rigid and suits pipes on show or near the boiler. Plastic is quicker under floors and inside walls, and long runs need fewer joints.
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.
