Cement or threaded for PVC fittings?
 

Basically which is better for use in a PC? I think threaded would be a little stronger, but assuming I'm not going to bang things around too much the cement would seal better.

I watched a friend seal some stuff with cement once. Basically I need some purle stuff (primer?) then some cement. Is this right? Its been a while and I didn't really pay much attention at the time.

I'm leaning towards unthreaded simply because its a good deal cheaper.

I would use threaded with teflon tape. It is easier and can be changed easier. It is not very expensive.

I won't ever need to change it, so thats not a concern.
