Working in Streatham
In Streatham we cover SE27, SW12 and SW16; we also cover Mitcham, 2.4 miles away, and Brixton.
In Streatham, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Streatham bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. For Streatham homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
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
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- A pressure test of new pipework before walls are closed in and floors go down
- A check of your hot water system, and the pressure and flow rate at the bathroom
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.
Copper or plastic
Copper is rigid and suits pipes on show or near the boiler. Plastic is quicker under floors and inside walls, and long runs need fewer joints.
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.
