Cutting pipe against a wall

[sunbeam59]

I want to cut into a 15mm water pipe. I can't get a pipe slice in as it's against the wall!

Would cutting with a metal cutting disc on my angle grinder be ok?

Will the disc cutter cause contamination problems as it's the cold water pipe to the tap?

I would use a muli tool.

1. Agree with above, use a multi-tool.
2. If you must use an angle grinder, make sure its a battery one. Pipe is likely to have residual water, which won't go well with mains electricity.
3. Whichever method, run water through into a bucket when finished to wash away any debris.

Never thought about the electricity

I might dig out the junior hacksaw, but I always seem to end up with a sash-cut pipe!

any tips for a good cut?

1. Get a piece of paper, fold in half to get a good straight edge.
2. Clean pipe.
3. Put paper round pipe, line up straight edge together at front and pinch together.
3. Mark round with a Sharpie type marker pen.
4. Start cut following line. Once started, move round and start a new groove in a new place. Do as far as you can access round pipe.
5. Cut though using start grooves.

A full size hacksaw blade (32 tpi) (e.g. Screwfix 3841X) with insulating tape wrapped around to form a handle is better than a junior hacksaw. Even easier to use if fitted in a part frame like Screwfix 5028V, particularly if you reverse the blade to cut on the pull stroke.

Excellent, thank you. I'll give it a try

I've used a mains grinder many times. The pipe would have to be live/pouring out water to cause a problem. Any drips just get thrown off by the blade.
