Working in Coulsdon
We work right across Coulsdon — CR5, CR8 and SM7 — and in neighbouring Purley and Banstead.
In Coulsdon, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Coulsdon home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. If your Coulsdon bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Water across much of Greater London is 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
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- 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
Decisions to make first
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.
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.
