Thanks for posting this, you taught me how to fix pvc pipe inadvertently

I found this post the day after I ruined some light 4" pvc I was cutting holes in to run plastic cups of media. There was an old 5.6w "applicator" pen style soldering iron device in a load of salvaged items left over from after a tenant vacated a rent house. After heating the pvc I bunched up some plastic bag tightly and melted it into the heated pipe. After a couple of leak tests and resoldering the pipe no longer leaks.

On google one can find many instructional videos to watch the process beforehand.

You used a normal (as in not a shopping plastic bag) plastic to fix the PVC? Since reading this thread yesterday I've been trying to find out how to weld PVC with a soldering iron - also the plastic used for IBC's. I was thinking to maybe cut some very thin PVC strips from some old offcut pipes to use as 'solder'. I saw some youtubes that use the soldering iron with plastic bags but they were doing polyethylene plastics. The PVC ones all seem to be using special plastic welders.

I figure it will be fine for the barrels and IBC's but I wasn't sure about PVC, short of trying it out and it was pissing down yesterday so outdoor work wasn't on and I wasn't doing it inside... :)

I just used standard cheap sandwich bags which happens to be low densety Polyethylene. Melting the plastic into position wasn't very straight forward though what I used was on the low end of soldering irons.

When reading what plastic the bags are made with i also read that PVC plastic is made with toxic ingredients and should not come into contact with food...

This makes me rethink my planter strips.

Hm... so I will check Mitre 10 and see if they have any of the plastic 'welding rods' you see in the youtubes... Thanks for the link - plastic milk containers could be the go...

Will do ccBear

I'm looking to weld blue barrels so this thread is just in time.
I have welded plastic 30+ years ago and it was very easy to get to grips with it.
IIRC I used a special show on the end of the gun and fed a 3 lobed plastic rod as a filler. The show was contoured to fit that 3 lobe shape as well.
This was on polyethylene wind surfers. I believe the blue barrels are polyethylene, anyone know for sure?
And what is the plastic the IBS's are made of?

Excellent, should be easy to produce a strong weld.
Thanks

Matching plastics is the hard part, a trick is to cut off fine strips of the thing you are trying to weld.
