Disconnected washing machine, but water still flowing. Aaargghhh!

[Primotomb]

I needed to disconnect washing machine as moving later this week.

Turned water supply to washer off using the little blue tap and disconnected the inlet pipe from the washer, but water is still coming out of the pipe. I.e the little blue tap isn't fully turning the water off.

I'm guessing I need a plumber and there's no easy fix?

Yep an end cap is an easy fix

Can I get an end cap that screws onto the hose? The hose is still connected at the pipe end. I've had a look on screwfix but couldn't see anything that would fit

Thank you. I cant get a picture, it's hidden under the back of the sink, but looks exactly like your link.

The hose is still connected to the water pipe, because I can't get to it to disconnect it. Whoever put the plumbing in clearly didn't think about how anyone would access it once the kitchen cabinets and workshops were in. So my plan was to just leave the hose connected to the pipe, ready for my buyer to connect it to their washing machine.

Except it it is still pouring with water. I've hooked it over the sink for now (and cable tied it to the taps to keep it in place)

this is another attempt to answer the question. I got muddled earlier

Post a photo of this tap if you can.

I expect it is rather like this
The blue lever has to go at right-angles to the pipe to be fully shut off. Too far, or not far enough, and it will open again.

Try to buy a 3/4" BSP capnut tomorrow.

It screws onto the end of the tap, like the plastic nut on the end of the hose does. Leave the hose attached to the washing machine.

Don't be alarmed by its size. BSP sizes bear no apparent resemblance to their names. If you measure in internal diameter of the nut on the end of the hose you will find it about an inch, but it's called 3/4" because that was the internal diameter of the iron pipe that it was originally designed for.

Take your tape measure and verify that the nut you buy is the same size as the nut on the end of the hose.

Screwfix do have them, they are listed under a different name.

If you buy a couple, the spare one will probably come in useful one day.

If you can get one with a flat rubber washer included, it will make a better seal.

In that case, buy another valve, and screw it on to the other end of your hose. Turned off. The hose has the same size nut at each end, one is usually straight and one is usually angled.

Can you reach the lever to verify that it is really at a right angle?

OOI, in UK, these valves are usually put at the back of kitchen cabinets. In Germany, they are placed at the front so they are easy to get at. What a good idea!

Brilliant, will give that a go in the morning. Thanks for your help!

Just coming back to thank @PigletJohn agsin. Connecting the free end of the hose to a new valve worked a treat as a temporary fix while I wait for a plumber to replace the faulty valve

It's genius, isn't it!
