HELP! - Accidentally sawn into heating pipe!

[barrycrook]

Hi All,

I was taking up floor boards today and i have sawn/grazed one of the central heating pipes in the process. There is no leak but there is about a few mm graze/cut in the pipe and i was wondering what the best action was.

Is it safe to ignore/leave or does it require filling with solder? I did try this but as the floor boards are around the area, they started burning so i stopped!

I'm just worried it may start leaking in the future as a weak spot in the heating system?

Regards

Barry

You shouldn't leave it.

The floor board will have to come up, whatever you do, you'll also need to drain the pipes.

Solder a patch may be all thats needed, but the best plan is to cut it out and use a couple of sockets.

That looks deep, I wouldn't leave it like that if I were you.

Defiantly agree with above might take some time but would be worse if it does start leaking

2-3 hours you sorting the pipe out or 2-3 weeks sorting out the rooms below once the pipe has split.

You Deicide!

there's nowt so dangerous as a householder with tools!!

As suggested but not said, you'll never be able to solder any pipe with water in it. It will be best to drain down, finish the job of cutting through the pipe, and use a slip coupling of your choice (capillary, solder, compression, or push fit) to fix the pipe up.

.... compression, or push fit.....

I'd say there's not enough room for either.
Blowtorch time.

Drain, lift floorboard, cut pipe either side of joist, solder in a new section of copper tube.

I hope your soldering is better than your sawing.

& looking at the depth of cut on the joist i think you need to lower the bed of your saw by 20mm

 

[muggles]

Off with his head!! And out with the cut, time to solder a new section in

Pic 3 shows the cut board going under carpet gripper, which would indicate there being a wall there, this would enable you to carefully prise the short piece of board up without risking any cutting it.

There will be another joist just off the wall, and you must carefully pre-mark out, & pilot hole, where you will have safe fixing points thro the board and into the joists for the new piece of T&G. Screw the T&G down.

If you have a partition and the (rad ?) pipes run under it then come back here. But i should imagine that the pipes are a F&R from a local rad on your side of that wall.

We don't generally take underfloor F&R pipes through walls, when doorways are available.

Lets face, it's being 7 hours since the op has posted. So hopefully it's all sorted by now.

sooey,

neither would we, but i mentioned a partition, which of course, is planted on the T&G, occasionally, long after the pipework has been run.

AAMOI: we will sometimes pierce masonry rather than snaking and disrupting about the rooms.

Andy,

This is a public forum of record, to help now and future DIY'ers. The date/time factor is hardly relevant.
