Fitting Ball Valve Issues, please help.

[ZINXYX]

Hi,
I am in the process of replacing a 22mm gate vale on the cold water feed to a shower. I had to cut the gate valve off because I just couldn't unscrew it , no matter how hard I tried.
In the process of fitting the new ball valve, I have found that the pipe is a few cm short and does not go into the ball valve at all. As a result I can just about about screw it tight. This really makes me uneasy.
What will you recommend to make this pipe a little longer? Also should I use jointing compound on the compression fittings?

Thank you .

You are confusing me with Gate valve then Ball valve in your post but if you cut the pipe to remove the gate valve then you shouldn`t be surprised the pipe is now too short.

Somewhere you have to add a straight coupler and use a new length of pipe to reach the valve.

Thanks rpm. sorry i meant to say I was replacing a gate valve with a ball valve. I will need to solder with the straight coupler won't I? Is there an alternative without soldering?
Cheers

Does the ball valve have a lever to turn the water off or is it a screwdriver slot type?

It has a lever.

It has a lever.

Good choice!

Any more advice please?

You need the pipe to fully engage so you're right to be uneasy. Easiest thing is cut the pipe back further and cut a new length of pipe. Then use a compression coupler at one end and the lever valve at the other to make up the gap. Yes use compound

See you`ve edited and added about soldering now. If your not confident in your ability and the straight connecter will be on show not hidden away then a compression fitting is what most DIYERs use. My view is that no tape or paste should be required but views do differ on this subject.
