Hi, I bought a mixer tap brand new and installed it myself. It was a clearance item and I bought the last one so can't find any info about it online. When I turned the tap on, it leaks profusely from the top of the nozzle (see red arrow). It's a pull out nozzle which seems to be loose where the 'hose' connects to the nozzle. I'm not sure if this is a faulty product or whether I could actually pull the nozzle apart and tighten. Since I bought the last one, I got a really good deal so I don't really want to take it back as I would have to spend at least double on a replacement of a similar model. Pic attached.
