Another way is to block the pipes with a plug so the water stops, dry the the
ends and glue on a threaded coupling. Then you are able to remove the plugs,
because the pipe is not closed yet and you are not trying to glue in moving
water, only tighten threads until the leak is gone. In metal the piece is
called a split union, I think.

so, anybody know of either a pvc cement that can be applied and used while
the pieces are wet, or else a way to plug large pvc lines internally, then
remove the plug after a fitting is installed? the fittings are union
fittings and ball valves, so I'll be within a few inches of the plug, but
the hole it has to come out is a good bit smaller than the i.d. of the pipe.
If the water isn't under pressure you could just take the caps off for a day
or two and wait for physics to run its course; sooner or later it will be
done.
Or: stick a balloon down the pipe, one of those long make a dog kind. And
pop it once the union is in.
