"Bought two of these for a new utility room installation on the strength of other good reviews here. As others have said the valves look to be well made and of course the main bonus is that they are full bore. Will give them a bit of time to check reliability and if all goes well I'll be changing all my ageing gate valves for these little beauties. (Most of which are seized open)."
"These Full Bore 15mm Lever Ball Valve are very reliable to shut off water supply completely when required for repairs or any other reason. I previously used a Stop Cock that had a rubber washer but found them to be unreliable, as the washer either leaked or the Stop Cock jammed due to residue from the hard water."
