How do I switch off the water to my taps?

A common question we're asked is 'how do I switch off the water to my taps?'
If you don't have isolator or service valves it's not that easy and can mean shutting the water at the mains.
So it's always good practice to fit isolator service valves (sometimes called ballofix or ballfix valves) which can be closed simply by turning the valve with a screwdriver.
These should be fitted to taps, showers  and other domestic appliances including washing machines.
As part of tap accessories, we are now supplying Isolator Service Valves available as either 1/2" BSP to 15mm compression which goes between tap flexitails and copper pipe, and 15mm x 15mm compression which goes between copper pipe.
Each isolator valve is screw operated - something that prevents accidental shutting of a valve
