Routing air

[LizStreithorst]

I glue mine.  The PVC heats up and gets bigger and if not glued the connections will blow apart.

I am wondering if I really need to glue this together though. But i probably will.

I don't glue mine..... for what it's worth.

Most the folks that I know don't either.....it's not much pressure...but if you think it's a big air lose, put a light coat of caulk around the seams...but if snugged up good, I'd leave it too...if you do any modifications later, it'd be a lot easier...

That's the key.  Less pressure greatly extends the life of your pump.  Bleed off any extra air to keep the pressure as low as possible while still delivering air to the tanks.

Sometimes for low pressure I will glue PVC with silicon.
It holds things together better than no glue, but you can still take things apart easily when you want to change things.
