Hi. Someone took old machine away. The red and blue valves were turned off. The hose was disconnected from under the sink but when I run the sink tap the water comes out through the connection under the sink. There is one hose left and it's connected to the blue valve. I'm really confused. No man here to help me

 

It sounds like the drain hose was disconnected from the drain but not capped.
Can you shoot and post a picture of the plumbing for us ? http://www.doityourself.com/forum/el...-pictures.html

 

I hope picture attached ok

 

Pictures sent. Thanks so much

 

Question you are saying it is leaking out the pipe at the top of the u fitting? There is just a opening there?

 

That looks like a slip nut fitting.

 

Good job with the picture.

I agree with Norm.

Something just looks wrong with that drain setup.

The trap is sitting the wrong direction.... almost like the fittings were turned. The hose connection point should be pointed right.... not up.
Can you take a second picture showing us more to the left ?

 

LOL the pic is side ways... IMO remove that barbed fitting and install a normal tail piece...

 

Well I rotated it but that doesn't look right either so I ran the IP. The member is in the UK. All bets off on how it should be.

Dympna, you need to update your profile so we know where you are. This is primarily a North American forum. Your picture is different from how we do it. We do not attach the washer discharge directly to the drain. We just have an open stand pipe the drain hose rests in but is not connected to, just hooks over the opening.

 

I also rotated it. And I agree still looks funny.

 

Dympna, just for your info and to explain why we are confused here is how it is done in the U.S.

 

I reoriented it in the opening post. Maybe it will need to be turned back but it looks correct now.

That makes sense now how the water is coming out. The locknut doesn't look tight and of course the end of the pipe is open. Looks like it needs a rubber cap now.

 

If you don't want to redo the pipes, the barbed branch must be plugged or capped. There's no off the shelf items to do that directly.

The barb looks like 7/8" OD.
Use a short section of 7/8" ID hose, it's called garbage disposer drain hose or washing machine hose here.
Clamp the section of hose to the barb.

You then plug the end of the hose. There's no standard plug. Use a 3/4" Copper Pipe Stub out or a 3/4" Copper Pipe Cap to plug the hose. You might have to grease the copper and force it into the hose.
Either way, find something that fits snuggly into the end of the hose and can be clamped.
