Pipe repair
How to repair a leaking pipe - a beginner's guide
The homeowner decided to install a fountain by wacking a nail through a floorboard and into a pipe.
Parts & tools - a couple of fairly big screwdrivers were also used as levers to move the pipe a tiny bit so the nut could turn.
You should be able to do it without spare olives, but I've had enough incidences of needing a new olive to always take spares.
Mark where to cut the pipe. Usually a rotating wheel type pipe cutter woud be used, but here there was no space for one. An oscillating saw was used - a hacksaw is also possible.
Olives won't fit onto a sawn pipe end, so the pipe ends were filed to remove any external burr. This required getting the file in at a few odd angles.
Slide nut then olive on
Add linseed putty.
Some people think you should never use gloop with compression fittings because they were designed to be used dry. Choice is yours, fwiw I find they're more reliable on used pipes with putty.
Tighten each nut; the 2nd wrench stops the new plumbing rotating. I removed a 2nd floorboard to get enough tool access.
Job done!
This was a heating system pipe. So refill & repressurise heating according to boiler instructions. Add corrosion inhibitor ditto.
Nail floorboard back down, then you can repeat the whole process.
