Working in Paisley
As well as Paisley itself (PA1, PA2 and PA3), we survey in Barrhead, Renfrew and Johnstone.
Across a large town like Paisley, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. If your Paisley home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. In Paisley flats, any change to the WC or wastes is planned with the title deeds and the flat below in mind.
Most of Renfrewshire and Inverclyde 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.
What the job includes
- 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
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
Decisions to make first
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.
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 Scotland
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.
