Help!!! PVC Pipe (Threaded)

[coalcut]

I'm using a few threaded PVC parts for my filtration.

Does any one know if you have to use PVC cement on threaded PVC pipe? I've heard yes and no. Some state that the cement melts the threads and causes failure so some type of PVC sealent should be used instead. Is that true? I've also heard not to use pipe tape as that is for metal pipes not PVC.

Any Thoughts?

Thread tape is for metal and plastic. U don't use the cement on threads, only thread tape or paste.

Thanks. I thought so but just wanted to make sure.

Being for an aquarium, I would just use the tape and not the paste

use white teflon tape for the threads. Do not use paste it contains chemicals.

I'm not even using cement on my push in pipes and don't have any leaking. Then again, all of my piping goes over my sump so even if there is a small leak it has nowhere to go but into the sumpl

I use cement for push pipes but I don't think anything is needed for threads. Mine don't leak at all.

If you want to be able to take it back apart at some point, then use tape. And PVC cement is perfectly safe to use in aquarium plumbing, it just needs to be allowed to fully cure.... usually give two days.

I dont even let it cure. I just use it.
