Plumbing question - bulkheads and pvc

[Monkeyfish]

Hey all,

I'm finally ready to plumb the 180. I have slip fit bulkheads on the tank drains. Do I need to use the pvc primer and "glue" when I insert the pvc into the bulkheads?

On a side note - I LOVE my dremel!

Yes, I'd use the clear primer so it looks nice. The Primer will insure a tight and permanent seal.

I've seen just glued joints leak in a friends set-up.

I would also use silcone.

Eric, I agree with Tim and Mike: I used silicone around the gaskets and used the purple glue on the pvc.

I'm going to disagree about the silicone, it's not really necessary the gasket works very well on it's own. just don't overtighten the bulkheads. And i would use primer and glue on the outside, but if your making a durso or similar on the inside of the overflow it can just be slipped into place without glue. and the only difference between the purple primer and the clear is a dye so you can tell that it's been primed, so i would use clear if you can find it, the purple stuff is a mess.

bulkheads are tricky, but the key is, like scott said, not to overtighten them. that usually results in the leaks. that purple stuff works great though on the pvc.
