Hiya, I bought a garden tap kit from toolstaiton, and it comes with this (pic below). So, does any one knows what the purpose of this looks like isolation valve for? Or it's not an isolation? Could i just by pass it? Thanks!

Hi, Old house we moved in to seems to have a faulty 15mm Isolation Va lve but because of the way pipes are, theres a problem. No extra pipework to allow me to chop out pipe and fit new valve as all pipes lengths tightly routed. ONLY OPTION IS to unscrew current nuts at ends of existing...
