Being a smaller town does not change how we work in Longfield: free survey, written quote, one team. In Longfield flats, any change to the WC or wastes is planned with the lease and the flat below in mind. Plumbing surveys in Longfield include a look at the existing pipework for lead, corrosion or poor support before we quote.
Water across much of Kent 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 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
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
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.
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.
