I have a
PORTER-CABLE 0.8 HP 6-Gallon 150 PSI Electric Air Compressor.
I want to create suction to pull air out of a line going to a swimming pool.
I am trying to seal a plastic pipe with glue and want to suck some glue into the gaps around the join.
How do I do this?
Fix the gaps around the joint. Plastic pipe is made to be joined
without vacuum.

Think about what you're trying to do.
If your vacuum is perfect, you can get ~15PSI differential pressure.
Now, take the cross sectional area of the gap you're trying to fill.
Note that the actual force applied is miniscule.
One of two things will happen.
1)The force is insufficient to move the glue and nothing happens.
2)The force is sufficient to move the glue and sucks it all out leaving
a hole.
I wouldn't count on that perfect storm of pressure, hole profile
and glue viscosity.
BTW, will I damage the air compressor if I get water inside.
Every air compressor has water inside. It condenses out of the air.
But if you suck in too much at once, depending on the pump design,
you can bust it instantly...or not...
Chlorine doesn't help.
I wouldn't do it.
