Review: good product - it was a direct replacement and fitted exactly and worked well
Review: no more leaks - a perfect like for like replacement for my dripping valve . It has been reconfigured from the original in that the 15mm outflow pipe is an easier connection due to it now being a swivel connector. Since there are three 22mm pipes to hook up and the 15mm outflow you would probably otherwise need a 'union' to be able to make the connection to the tundish. Worked great and an easy fit ......
