Get a inflatable stiopper with air extension hose. Install it and
inflate. Install a ball valve passing the hose and chain from the
stopper through it while installing. Take care not to let pvc glue
run down onthe stopper. Deflate and remove the stopper when the glue
has dried. That's how a pro would do it.
Don't know. I did it on galvanized wrapped in lead.
This was a 2 inch main gushing water at a pretty good rate.
Just checked, you're right PVC isn't very conductive at all.
My guess is that it would still work. You could stuff
the dry ice directly into the water flow I suppose.
I doesn't sound like this well is generating a lot of
pressure. Just take a chunk and push it into the water
My story is that I got a quote for 2.5K to repair the
leaking valve. All of the cost was digging up the street.
I already had a replacement valve.
My neighbor told me about this. 5 bucks worth of dry ice
vs. a $2500 repair bill.
You'll need to shut off the water flow with a temporary cap first,
then it will probably work. Just freeze it from the outside (even
though it's plastic pipe) and give it time to work.
Be careful not to break the pipe while it's frozen.
