Correctly capping cold feed

[gnvqsos]

A tradesman has capped a cold feed by attaching a service/isolation valve in line They have turned the slot to horizontal but have not used a 15mm tail with a stop end as a safety feature .Is this good practice.?

Not really but it does the job. However, it leaves a possibility of someone trying the tap to see if the pipe is 'live'.
You can buy a plastic end cap that just slots over the end of the pipe by pushing it on. To remove it at a future date you have to push up a collar before sliding it off.
Probably cheaper, and less hassle, for you to do this yourself rather than trying to get the plumber back out.

What if the service valve fails? We were taught that valves need to be backed up using screw cap or with stop end and tail.

Using a ballofix is a slightly more expensive way of doing it unless it was the last isolating point in what was being removed. As conny said- a push fit stop end would be a more normal way of doing it. You can always put a bit of pipe into the open compression end of the valve and nut it tight and stick a compression or push fit stop end to stop the potential leak point I’m for peace of mind- which I would do myself.

But if it was a cold feed, putting an isloation valve means the pipe can be used for something else.

Personally I would have fitted a quality isolating valve (Pegler or similar) to make things easier should it need to be reinstated, with a short length of copper pipe and a stop end, I don’t trust some of the unbranded, cheap ball-o-fix valves.
I know it’s a bit “belt & braces” but better safe than sorry.
