Working in Finchley
We work right across Finchley — N2, N3 and N12 — and in neighbouring Muswell Hill and Cricklewood.
In Finchley, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. In Finchley flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Finchley water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
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
- A pressure test of new pipework before walls are closed in and floors go down
- 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
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.
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.
