Working in Harpenden
We cover every part of Harpenden, including AL5, and nearby St Albans (4.7 miles) and Luton (5 miles).
In Harpenden, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Harpenden water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads. If your Harpenden home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.
Supplies across most of Hertfordshire 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
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- A check of your hot water system, and the pressure and flow rate at the bathroom
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- 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.
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.
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.
