Which towns do we cover in Greater Glasgow?
Water across much of Greater Glasgow is 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. If your Glasgow bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
What the job includes
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- 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
- A check of your hot water system, and the pressure and flow rate at the bathroom
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.
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.
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 Scotland
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 Scotland, the Scottish Water Byelaws 2014 cover new water fittings, with the same 6-litre flush limit and backflow rules. Altering drainage may need a building warrant, so check before moving a WC or adding a new connection to the stack.
