You can use the clear in the yellow can but if it is being inspected
they want to see a little purple ring on the pipe at the joint. The
cleaner/primer does make the joint much stronger. It breaks the
surface oxidation and allows the cement to penetrate better,

Also depends on what he means by "working with". If it's for water pipe
under pressure, I'd say absolutely yes. If it's making one joint to
make a reaching pole to poke at something, you can probably get away without

Couple of things. I assume these tests were done at room temp. IMO, too
many tests at room temp, none at min and max temp. I think min is ~40F?
Solvent could have a more significant effect at temp extremes, perhaps
at low end. And what kind of pipe? Brand new PVC? Or twenty year old
PVC that your are patching onto? Nice and clean? Or with some dirt on
it? Yeah, we know it's supposed to be clean, but we all know what happens
anyway. That solvent is loaded with acetone and you can see it melting
the plastic, so any old surface, some dirt is going to get taken off
and at least distributed around the joint, leaving fresh PVC exposed.
The glue itself is thicker and seems less likely it's going to work past
old PVC, dirt, etc.

What was really interesting was the time it took to develop full strength.
Those tests showed 24 hours, while most people (including me) assume these
joints are strong pretty much as soon as they set. I would think in cold
temperatures the strength would develop even more slowly.

I think the cement cans say something like can be handled in X mins,
OK for X lbs pressure at 2 hours.... IDK what the exact numbers were
but I know it said something like that. And also I think that was at

That is what the blue is for. It sets in 10 minutes or so.
Most guys doing repairs use that.
One thing they didn't address is the "cleaning" part. If that pipe has
"been around" the surface needs a good scrubbing, particularly if it
was underground but just being out in the light makes them get a
chalky coating. (like in that outside bay at Lowes/HD where they store
it before it comes inside).
Virtually all trade suppliers store it outside.
Cure is essentially solvent evaporation which would be slower at lower
temperatures. Solvent slowly diffuses through the PVC. Odor may remain
a long time after the joint is about as strong as it is going to get.

I had to repair some PVC several weeks ago. I was just looking at my
can of PVC adhesive and it gives specific instructions about wiping off
the cut part after chamfering and then how to apply the adhesive. There
was nothing about using PVC cleaner.
