hello folks,to start with i apologise in advance for my numpty question and my lack of knowledge,but i guess that's why you guys are here.
I have a leaking nut! The main cold water feed coming up under my kitchen sink is a large (28mm?? a 22mm olive won't fit over) thick blue plastic pipe and has a brass stopcock attached to it,leading up from the top of the stopcock is more of the same blue pipe attached to the stopcock with a large blue plastic nut,further up there is a weird reducing fitting (push fitting on the blue plastic pipe side/compression fitting to grey 15mm plastic pipe) which leads up to a brass T compression fitting which branches off to the washing machine and my sink. After discovering water all over my kitchen floor i sourced the leak back to the big blue plastic nut,after shutting down the water from the outside stopcock i removed Big Blue Nut using some swanneck pliers,wrapped PTFE tape around the thread of the stopcock and up the pipe around the olive and rubber washer and replaced the whole lot. I turned the water back on and i'm still leaking at the base of Big Blue Nut,it also seems to have a split in it as there is a very fine jet of water. Is there a brass compression reducing fitting that i can use to get rid of all the plastic pipework and replace with standard 15mm copper pipe up to the compression T fitting? Sorry for my long winded explanation but as you can tell, i'm no plumber and without uploading a photo i thought i'd try to give the full picture. My house is less than a year old so i'm guessing that metric size pipes have been used. Please help as i'm getting pi**ed off with getting wet feet! Thanks,
Chris.
