Emergency water pipe fitting

I'm doing some trenching at the weekend and there is a chance I will run through a water pipe as the land owner 'knows it's in there but not sure where'. I am talking about the blue plastic stuff.

So I was talking to a mate who does ground works for a living and he recommended I buy an emergency fitting that can shut off the pipe whilst you figure out how to fix it.

The thing he is on about he says 'screws on the end of the pipe, then you tighten it down to stop the flow'.

Problem is he has no idea what this thing is called and Google isn't coming up with much. Does this sound familiar to anyone and if so can they shed any light on what to search for?

Thanks, Chris

That's what I found, but he says this is something different.

You have to cut the pipe off so there are no jagged edges, then it fits over the end and you screw it down to stop the flow.

Much better than a squeeze tool apparently but just can't tell me what it is I need to look for!

If you know the pipe size (access at one end?), you could just buy a full-bore ball valve. Leave it fully open and then if needed slide it on, lock it in place and close it. Rather like the old way of closing off oil wells.

yea, that should be easier than just trying to cap it off, and also makes re-connection easy too

unless you know the size of the pipe, you are better off with the sqweazer





I'd love to give my imaginary friend a great big hug,

but this jacket makes it impossible.

In an emergency you can dig a bit more of the pipe up and bend it out like you would a garden hose.

Whack a bit of tape around it to stop unfolding.

Not going to work for large bore but normal water feed pipe you can

May we ask what you're putting in the trench - pipe, cable etc?

If you locate and dig carefully around the water pipe can you lay whatever it is over or under the pipe?

Alternatively do you have access to a stop-cock or similar to turn the water flow off in case you cut through the water pipe?

Not much help as you will need a couple of sizes depending on the size of pipe you encounter.

Fibre optic cable. Well actually a plastic tube into which a fibre cable will eventually be blown.

We have ~4km to do and are using a trenching machine hence 'being careful' is kind of difficult. As I understand it (first time I will have used such a machine) by the time you know about the pipe it will be too late; it's basically a chainsaw for the ground mounted on a set of tracks.

Since I've not managed to find out what this magic tool is I've invested in a 'squeeze off' tool (£25 from Toolstation) and a couple of stop cocks. Hopefully that should get us out of any trouble.

OK - not used that type of machine myself either, but can see the concern!

Hope it goes well
