Hello,

Should I purchase a ball valve marked 'high pressure' or one that is
marked 'low pressure'? It's for the water tank in the loft fed by the
rising main.

Hope I make sense

Wayne.

Depends on your interpretation of high and low pressures. Do they give any
number, such as 250 WOG? You can always use a high pressure in a low
pressure situation, but not the other way around so why not be safe?

My SWAG is that low pressure is for gas lines.
