Browse Forums Bathrooms and Laundry 1 Feb 12, 2010 6:07 pm I want to replace the old & hideous orange sink in my bathroom to something a little less orange. At the same time I thought I'd replace the rigid supply lines with flexible ones. However, on closer inspection it appears they lead straight into the concrete behind the vanity. There doesn't seem to be a way to remove them without cutting them off. What are my options? It seems a bit risky to buy a new sink and taps and hope they line up with the existing lines. Here's a picture..

The copper is anealed and will bend when the new bits are added... Flexi... just another place to leak to be truthful. Where you are coming from is where you are going to... Re: Replacing copper supply lines, no nut? 3Feb 12, 2010 6:49 pm Hi, I am guessing you might get a vanity with a flick mixer type of supply. These are supplied with a couple of flex hoses, and they must have a stopcock at the wall under the vanity. Your plumber will not blink, he will just cut or unsolder the existing stub there, and install stopcocks for you. They are cheap as well. If you are to have the standard setup of 2 taps and a spout on the new vanity, then I believe extra stopcocks underneath are not needed. Mention your plans to the plumber and he will just cut the stubs and install a threaded adapter onto each pipe at the wall to take the flex hoses (nothing wrong with these IMHO ). Another possibility is that the threaded adapters exist already at the wall, and will become visible when you remove the vanity. To do so you need a special sort of spanner which can undo that nut high up just under the taps in the photo. This is sold by hardware stores. Cheers Re: Replacing copper supply lines, no nut? 4Feb 12, 2010 7:10 pm I'd be cutting the copper pipe with a splicer (can get from a plumbing supply shop, little round thing) and then using a cone tight with a male thread. Then attach a chrome tap like that used in the dunny. Then the flexible hose then goes on the tap. You would need to be pretty confident to do it though. Cone tights are only allowed to be used in WA to the best of my knowledge. Hey you can also use those adapters for converting from copper to the plastic pipe. They are very easy to install. Either way you'd need to cut the pipe. When using cone tights, a very good idea to use thread tape around the cone before tightening together. Re: Replacing copper supply lines, no nut? 5Feb 12, 2010 8:27 pm A plumber would cut the two pipes on the horizontal part where they leave the wall and then silver solder two male iron adapters onto those two two pipes. If theres not much room, soft solder them. then as someone else mentioned screw two two right angled mini cistern taps if connecting onto a flick mixer and then connect the flexi connectors from the mixer to the mini cistern taps. Be careful when buying mini cistern taps as the cheap ones with a round handle tend to leak from the spindles after a while. The best are ARCO, which are a ball valve and have a non return valve built in. Id be careful about using compression type fittings as someone suggested as they have a habit of blowing off, or loosening when people move stuff in the cupboards around. Remember, your insurance may not cover you if youve done it yourself and it leaks.
