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?

 

[ZINXYX]

It has a lever.

 

[rpm]

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.

to be honest RPM I'm inclined to agree re paste but i say use it as its all bases covered should something go wrong in a DIY project

lol. Well I did say views vary, I use a couple or wraps of ptfe tape on the olive if it`s an old joint I`ve separated but nothing on new, each to there own.

Never use tape never got on with it

Never needed paste, there you go Chalk n Cheese. lol

If the Pipe is slighlty short you will need to cut in and add a straight either compression or solder and a short bit of pipe,

as to jointing compound as Rpm says you shouldnt need any on a new joint, although i always use a smear of lsx on my joints as its belt and braces stops any potential leak if the pipe gets knocked
