Working in Windsor
We cover every part of Windsor, including SL4, and nearby Slough (1.8 miles) and Egham (4.1 miles).
Homes in and around Windsor vary, so we look at the floor, the walls and the water system before we price anything. Plumbing surveys in Windsor include a look at the existing pipework for lead, corrosion or poor support before we quote. If your Windsor bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Water across much of Berkshire is 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
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- The WC connected to the soil stack, or a new branch where the WC is moving
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- A check of your hot water system, and the pressure and flow rate at the bathroom
Decisions to make first
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.
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.
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.
