Working in Barnet
As well as Barnet itself (EN4, EN5, HA8 and 7 more postcode districts), we survey in Potters Bar, Borehamwood and Finchley.
London homes in Barnet often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Barnet water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads. In Barnet flats, any change to the WC or wastes is planned with the lease and the flat below in mind.
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
- A check of your hot water system, and the pressure and flow rate at the bathroom
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
Decisions to make first
Gravity or pumped waste
Gravity drainage is always the first choice. A shower waste pump or macerator solves a run that cannot fall, but adds noise, a power supply and servicing.
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.
