Dry fitting Cellular Core ABS

[Weekend Handyman]

Hello:

Just wondering. Can I dry-fit cellular core ABS?

I now you can not dry fit solid core PVC or ABS; however, the cellular core stuff seems to seat more deeply when sizing things up.

Thank you

No dry fit, the pipe will push in farther with cement on it.

1.5 and 2 inch are super easy to dry fit. 3 and 4 can be done but you have to make sure your fittings and pipe are super clean and they're difficult to separate.

I am running 1.5 foam core ABS, so that is helpful.

Then the nominal socket depth is 11/16", so you can mark 11/16" from the end of your pipe segments to see if your dry-fitting is full depth (or close enough) or not. Equivalently, if you have everything dry fit, you can measure between hubs and add 1-3/8" to check if your pipe segments are full length (or maybe just add 1/16" or an 1/8" less to give yourself a little leeway).

I will give it a try and let you know the results.

I find that most DWV installations don't need to be accurate to the 1/16..

I think that most rough in can be done with tape measures equipped to the "About" degree of accuracy.

Sure, but being systematically 1/16" short at each joint can add up and be a problem. Depending on how many fittings are involved.

Now if you dry fit, mark the dry fit insertion depths, find they are all 5/8", and then glue it up without the extra 1/16" of insertion, that's presumably fine, and your result should match your dry fit.

Tape measure? when did we start using those? LOL
