I've just replaced my ageing washing machine with a new model. The new machine is cold-water fill only, so I have plumbed it in and it's working fine but I'm now left with a hot water connection that I don't need. Both the hot and cold water feed pipes are copper with a chrome 3/4" threaded end fitment (where the washing machine intake hoses attach) and each has a turnable switch/valve to turn the flow of water on and off; at the moment I simply have the hot water valve closed (as I no longer need the hot water feed for the new machine) but I'd like to cap off the pipe completely just for peace of mind. If the valve was ever accidentally switched I would have hot water gushing all over my kitchen! I'm just unsure of how to go about this. Is there a fitting I can screw onto the end of the pipe to cap it off, or do I need to have it soldered? I've seen 'socket end' fitments in Wickes' plumbing department but I'm not sure whether this is actually what I need.
The fitting is a cap with an extermal thread and a taper for the olive to seal to. If you remove the valve you'll have water gushing out so find a valve further upstream first.
Go to a plumbers merchants and explain the problem, they should have a 3/4" B.S.P cap to fit the valve. You'll also need some P.T.F.E tape to seal the thread.
Chuck's "push-on" stop-end is the one that most plumbers use now. Either cut the pipe (use a proper pipecutter .......... a hacksaw leaves a rough edge that can cut the sealing ring.
Or ................. unscrew the on/off valve, take off the brass olive (might be difficult), then push the stop-end onto the bare pipe end. :o)
Thanks for the advice, much appreciated. The two pipes are underneath my kitchen sink and part of a very old plumbing system in an even older house, definitely not a modern easy-access system, so it really does need blocking off just in case the switch ever gets nudged and my kitchen fills with hot water! The brass end cap/stop looks like it will do the job perfectly. Thank you! :)
Lateral thinking ............... I knew cat's were intelligent. Of course, remove the handle (one screw). It's impossible to open the valve accidentally .................... doh!
