Working in Walton-on-Thames
As well as Walton-on-Thames itself (KT12, TW16 and TW17), we survey in Sunbury-on-Thames, West Molesey and Weybridge.
Being a smaller town does not change how we work in Walton-on-Thames: free survey, written quote, one team. If your Walton-on-Thames bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. For Walton-on-Thames homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
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 pressure test of new pipework before walls are closed in and floors go down
- 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
- The WC connected to the soil stack, or a new branch where the WC is moving
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.
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.
