Pipe to nowhere

[diynoob]

This pipe tees off the CH pipework and doesn't go anywhere. Is it there for expansion or something?



I have the CH drained down at the moment. Should I remove it or leave as is?

I will assume it's capped, for obvious reasons. Possibly a former expansion pipe, going up and over a cistern that has since been removed. If it's definitely CH, cap it lower down if you want to, otherwise leave as is.

Does it have a vent valve on top?

 

[diynoob]

Yes it does.

The pipe wants lagging there in the roof

 

[foxhole]

Yes it does.

It will be the highest point to allow complete venting of pipework.

OK Thanks. Yes it does seem to be the highest point in the CH pipework. Will test it when I refill the CH.
