Working in Great Sankey
We cover every part of Great Sankey, including WA5, and nearby Warrington (2.5 miles) and Newton-le-Willows (4.3 miles).
In Great Sankey, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Great Sankey home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. If your Great Sankey loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Most of Cheshire has moderately hard water. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Great Sankey. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- A survey of the headroom across the room, with the usable height marked at each fitting position
- A check of the floor joists where a bath or large shower tray will sit
- A check of your hot-water system and of the pressure and flow you actually get at loft level
Decisions to make first
Gravity or pumped waste
Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
