Most of Merseyside is supplied with soft water. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier. If your Liverpool bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
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
- A pressure test of new pipework before walls are closed in and floors go down
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
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.
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.
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.
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.
Rules that apply in England
New WCs, taps, showers and valves must meet the water fittings rules where you live: a maximum 6-litre flush for new WCs, backflow protection, and no pump connected directly to the mains supply, because shower pumps are only for gravity systems with a cold tank. Unvented hot-water cylinders must be installed by a G3-qualified installer, and any work on a gas boiler by a Gas Safe registered engineer.
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.
