"Bought for the washing machine water feed, the old isolator had seized up. This is a smart, solid item, makes the one it replaced look like a toy. Will look out for the same range when it's time to revamp the rest of the plumbing"
"Naturally due to the full bore configuration the valve is larger then the standard inline valve so a little more obtrusive but very sturdy. Fitting the valve delivers unrestricted water flow, robust isolation, avoids back eddies and blockages through the value."
"Never really thought about the bore reduction when fitting isolating valves until I tried these. I think I will need to replace a few of my existing ball valves with these full-bore units as they definitely made a difference where I've installed them so far."
"If you have 15mm bath or shower inets this product is great. The usual shut offs have a much smaller bore but this allows maximum flow without restriction. Allows the water to be isolated where you want without affecting the remainder of the house. Great for me when doing full refits. One of the valves leaked from the screwdriver slot where it turns but it was replaced without problem."
"For anyone who has used an isolation valve on a gravity fed shower then make sure you fit these full bore ones rather than the standard type. The difference in flow is amazing and makes for happy shower users without complaints of "low rate dribble showers". OK they cost a bit more but where non-mains pressure is concerned every drop of available pressure counts."
"Robust construction - Full Bore 15mm isolating valve - a little fatter and longer than the 'normal' 1/4 turn valves. Stiff to turn so needs a good size screwdriver, but isolates well. Only just fitted, so obviously can't judge long term use yet. I will buy more when needed."
"I'm not sure that there's a lot of benefit when installing full bore isolating valves over the 'standard' smaller bore variety when on mains water pressure, but as I was installing two showers I thought I'd give them a go.
They seem well made and look like they should be reliable but, like others, I found that the isolating screw head is somewhat hard to turn. Apart from that they are OK and a where decent price from Screwfix."
