"Ive used many different self cutting style isolators before. I purchased this one as my usual type was not in stock. The item felt cheaply made with a flimsy plastic handle on the top. Luckily I checked the valve before installing it on a live pipe, as it did not shut off. The internals then fell out into my hand. Fortunately screwfix are good at replacing faulty items with no hassle."
"I bought three of these thinking I could use them to break into 15mm pipe and connect to supply to small hand wash basin, they appear to be for use with washing machine hoses.Unless they do some kind of reducer. If you want to do the same as me I suggest you check out the ones advertised with the isolating valve and olive. I don't think this item is well described."
