Working in Amersham
As well as Amersham itself (HP6 and HP7), we survey in Amersham on the Hill, Chesham and Chalfont St Peter.
Amersham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Plumbing surveys in Amersham include a look at the existing pipework for lead, corrosion or poor support before we quote. If your Amersham water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
Most of Buckinghamshire has 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
- 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
- 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
Decisions to make first
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.
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.
