Turns a dribble back to a flow
8 Sep 2014
By
, Walton-on-Thames
"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."

"These allow for much better water pressure from your taps and shower than the standard isolating valves.
I have so far purchased and used around 8 over the past 9 months, and all have been of excellent quality."

"This full bore 15mm valve is exactly what the title says, it's full flow.
I previously use the standard valves with my new sink installation and noticed the flow was not what it use to be when the pipe were connected direct without any valves.
Later I replaced the standard valves with these Full bore valves and now I am getting full flow as desired. Very good quality and does exactly what is required."

Good for 15mm shower inlets
1 Mar 2013
By
, Glenrothes, Fife
"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.

Full bore means full flow
28 Nov 2012
By
, Norfolk
"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."

"If like me your property has low hot water pressure yet you like individual points of tap isolation then this a really good product, I was surprised how much basic isolators restrict the flow."

Difficult to turn
17 Jun 2014
By
, Lancashire
"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."

Does the job
24 Sep 2012
By
, Egham
"This valve is significantly larger than the narrow bore valve both in length and diameter. Overall length (without caps on) is 55.5 mm and the diameter of widest part is 28.5 mm. There is no obvious direction of flow with this valve so I guess it can be fitted either way around. The valve is quite stiff and the slot shallow so you need a good fitting screwdriver if you are not to damage the slot.
The body of the valve has a handy octagon on the body so you can use a 24mm spanner on it if you need to tighten or slacken just one end and hold the body steady. The end caps need a 23mm spanner"
