Working in Feltham
We work right across Feltham — TW4, TW13 and TW14 — and in neighbouring Ashford and Hounslow.
London homes in Feltham often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If your Feltham bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. If your Feltham water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
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
- A pressure test of new pipework before walls are closed in and floors go down
- The WC connected to the soil stack, or a new branch where the WC is moving
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
Decisions to make first
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.
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.
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.
