Working in Hayes
We work right across Hayes — UB3, UB4 and UB11 — and in neighbouring Southall and Heston.
London homes in Hayes often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Hayes water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads. If your Hayes home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.
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
- The WC connected to the soil stack, or a new branch where the WC is moving
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- 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.
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.
