ABS to Cast Iron: Any plumbers online?

[Joe Funderburk, CMI]

Shouldn't this be a mechanical connection?

[Marcel R. Cyr]

It appears they might have used one of these meant for that application.

That would be my guess also, as there are no signs of leakage in the pic.

Jeffery, to me that means a "rubber" type connector with clamps.

[Larry D. Kage]

I was thinking two of these would work well:

In my opinion, you would be partially wrong...

A rubber connector is not the same thing as an elastomeric seal. An elastomeric seal is a pliable/rubberized sealant when cured, (as opposed to oakum), or a manufactured pliable seal (such as an o-ring). Most likely this was installed with a pourable sealant, but you were there. What did you observe?

You also need to break the paragraph down...

Crawling in a wet, 24" high crawl space in 90 degree (F) heat and 90% humidity with mosquitoes buzzing around your ears ain't fun!

Hmmm...
Impossible to tell in the pic, but if I had to guess, I would say oakum, or (gasp) caulk, was used. Did you attempt to 'feel' the seal/sealent? If so was it 'rubbery'? I guess technically, (if it meets the listed standards) silicone would be an elastomeric sealant.

Didn't touch it. I guess I'll not say anything about it this time. I believe this is the 1st time in 6 years I've seen this. Maybe when I see another one I'll be better informed.

See, learn something new every day!

[Barry Adair]

i'd at least mention uncertain/undetermined dissimilar material connection

that way when it leaks or fails the day after closing...
