Working in East Grinstead
In East Grinstead we cover RH19; we also cover Horley, 7.5 miles away, and Crawley.
In East Grinstead, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Plumbing surveys in East Grinstead include a look at the existing pipework for lead, corrosion or poor support before we quote. If your East Grinstead bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Most of West Sussex has hard water. 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
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- The WC connected to the soil stack, or a new branch where the WC is moving
- A pressure test of new pipework before walls are closed in and floors go down
Decisions to make first
Hard water
In hard water areas, a scale reducer or water softener protects valves, shower heads and glass. Keep an unsoftened tap in the kitchen for drinking.
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.
