"Reduced flow isolators seem to be the norm. As well as restricting the flow, they tend to leak at the screw hole if they haven't been touched for a while. This defeats the purpose on both fronts. This full bore valve looks of better construction and feels "tight" and well engineered when the isolating screw is activated. I know they cost a bit more but are well worth it."
"Perfect solution for connections to showers where any restriction in flow could affect the performance. Very positive shut-off and efficient compression fittings at a very competitive price. Definitely the solution!
(Bank Holiday store opening was a bonus which meant the work could progress early)"
"I needed to isolate a section of the central heating to move some rads. So I put two of these on the flow and return of the heating so I can shut off that section without completely draining down. Worked perfectly with the freezer kit."
"This isolator may cost a couple of pound more than a small bore isolator, but it is worth the money. Slightly longer with a larger diameter but not a problem. Build quality looks and feels good, not had it long enough to comment on reliability. Ideal for pipes to the bath taps and shower where restricted flow may cause problems."
"For the sake of a few quid I can't understand why anyone would buy the cheaper non-full bore over these! If you have the two different types side by side and you open them up you can see just how much flow of water you are gaining by using full bore.
Unlike the more expensive Pegler ones with coloured handles, these come with Copper Olives and so can be fitted on Speedfit tubes.
It would be nice to have the choice of these with turn handles rather than the screw turn."
"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."
