Working in Dorking

As well as Dorking itself (KT23 and RH4), we survey in Leatherhead, Reigate and Redhill.

Dorking gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Dorking home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. For Dorking homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.

Supplies across most of Surrey are 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
Draining down and isolating supplies, with the rest of the house back on water as soon as possible
Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system

Decisions to make first

Gravity or pumped waste

Gravity drainage is always the first choice. A shower waste pump or macerator solves a run that cannot fall, but adds noise, a power supply and servicing.

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.
