PVC to ABS Bulkheads question

[dreamcatcherr9]

Should we be using this specifically? Instead of the standard cleaner and cement for PVC?

Anyone use this PVC to ABS cement?

Used the same one from Lowe’s on my build

Definitely best-practice. That being said i have used regular PVC cement and never had an issue. Now that I'm a big boy, i only use threaded bullheads with Teflon paste. ;)

I used regular PVC cement, holds just as good, if not better.

That transition cement sucks! It has no bonding strength. The last time I used it on a bulkhead, 6 months later I was able to grab the adapter and just pull it out of the bulkhead.

As above though, I now use threaded bulkheads with teflon paste. This way they are easier to remove, and you don't have to replace the bulkhead if you need to remove plumbing.

I saw a article (or video from EMS) mentioning or discouraging against the use of Teflon tape (?). Just curious if anyone else has heard this?

You are correct. And, Teflon tape and Teflon paste are two different things.

Oh! Ok. Thank you. Appreciated that little bit of shared knowledge!

Bingo! Key is, it's "suitable for potable water systems". :)

Slap it onto the male threads, and female threads, tighten w/ wrench and you are good to go. Make sure you have a few paper towels handy - the stuff is impossible to get off your hands (and clothes).

WOW! I used this when I replaced my water heater but never thought to use it on my aquarium. I'm definitely using it next time.

Not only does the paste actually seal better, it won't crack the fittings. THAT is a win-win :).

Yep. Plumbers call it pipe dope.

I used the ABS to PVC cement from Lowe’s. You still want to use the primer on the PVC side. It needs to be softened up a bit. Don’t use the primer on the ABS or it will melt it.
