Working in Sunbury-on-Thames
We work right across Sunbury-on-Thames — KT12, TW16 and TW17 — and in neighbouring Walton-on-Thames and West Molesey.
Homes in and around Sunbury-on-Thames vary, so we look at the floor, the walls and the water system before we price anything. If your Sunbury-on-Thames water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads. If your Sunbury-on-Thames bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Supplies across most of Surrey are 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
- 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
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
Decisions to make first
Concealed or exposed valves
Concealed shower valves look neater but need an access route for servicing. Exposed bar valves are easier to reach and replace.
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.
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.
