Old supply pipe

[mikeey84]

Hi All, in my kitchen, I have about a foot of old cast iron supply pipe sticking up through the floor, with a stop cock attached to the end, and then 2 inches of copper pipe bent over.

I would like to get rid of this, as its in the way of my new kitchen design. How can i tell that it is live? Obviously if its not, then I am happy to sledge hammer it out, but dont want to flood the kitchen!

I dont have a tool for turning of the mains, so to cut it and cap it lower down, under the level of the base cabinet, I would have to do it live (if it is live) and I dont fancy getting my feet wet!

Thanks

Opening the end were the copper pipe is then, opening the stopcock, with something to catch any water, would be a good option.

unfortunately the stop cock is seized closed and i don't want to force it. may have to bite the bullet and get a pro in who can turn off the mains supply and cap it/ get rid

Can you loosen the headgear on the stoptap, by undoing the large nut? Best not to undo it all the way, but if there is water in pipe, some will come out.

If it's really tight, wouldn't force it in case something breaks.

1. What floor do you have - solid or suspended?

2. It's typical to cap-off below the FFL or at the tee from the mains.

3. It's probably galvenised (not CI) pipe with a threaded stop-tap.

4. Dont you have an interior stop-tap?

5. Perhaps you can reach down the extn stop-cock box and manipulate the head-bar. Or a length of board with a vee cut on the end will act as a stop-cock tool.

stop cock is seized closed

If it's siezed, how do you know it's siezed closed? Especially as the pipe goes nowhere.

Hi all, will try and answer your questions....

It is all pretty well siezed, gave it a good blast of WD-40, and nothing was doing. I`m a pretty big guy, and coudnt shift anything, and I dont want to try levering anything, as i dont want snap!

Dann-
1) Solid- original 1910 quarry tiles
2) Not sure what FFL is?
3)I guessed its CI, as we had ST out for a leak on the other infeed and the guy said all our original pipe work was CI, not sure how i can tell if its threaded/compression. I guess if its threaded it would be easier to get rid and to thread a cap on?
4) Yes, our main infeed is in the bathroom at the back. This was disconnected last year, and a new infeed was put in by ST after we had a leak under our bathroom floor. The new infeed comes up the wall from outside and inthrough the wall, connecting with the existing coldwater pipework.
5) that sounds like a plan!

Charnwood- thats a good point, i imagine it is closed, as to why would you leave it open, but I should have learnt that with an old house never try and second guess the imagination of previous owners!

It won't be cast iron but if it is what they call 1/2 iron pipe then a 22mm compression fitting will fit if you change the olive for a 3/4 imperial olive.
Does it look the size of 22mm copper?
If so you can cut it short and put a stop end on or get a chip chaser and re-thread it lower.
Check if it's live by slackening the nut on the stop tap.
