Hi
Apart from the direction of the water flow through the valve itself does it matter which way the valve is mounted on the pipe work, vertical or horizontal.
Thank You
Martin
Hello Maaartin,
With a straight valve, it does not matter if installed vertically or horizontally.
Thank you for using Screwfix Q&A.
