I need a particular sort of pipe fitting to change my showerhead to the handheld variety.. found one in brass but it gave me allergic reactions (I hope it was the brass fitting, not the shower hose). We were looking for the same fitting in PVC.. looked in Mitre 10 and Bunnings, but no luck in either of them. Any suggestions for other DIY shops in Chch selling pipe fittings? Or even online shops that deliver to NZ?
