Which towns do we cover in Devon?
Supplies across most of Devon are soft. 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. In Plymouth flats, any change to the WC or wastes is planned with the lease and the flat below in mind.
What the job includes
- A check of your hot water system, and the pressure and flow rate at the bathroom
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- The WC connected to the soil stack, or a new branch where the WC is moving
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.
Concealed or exposed valves
Concealed shower valves look neater but need an access route for servicing. Exposed bar valves are easier to reach and replace.
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.
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.
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.
