I'm new and this is my first post.
There is an exposed cast iron drain in my basement. It looks like this. [i1369.photobucket.com]
I plan to replace with PVC. Would it be better to use a trap like in this picture? [i1369.photobucket.com] Or is it okay to use three street elbows like this? [i1369.photobucket.com]
Thank you in advance.

your trap's 'water seal' must be 2" MINIMUM
for a floor drain with little usage: 3"
for example of the principle :
your pic two is ok, pic three would have virtually no seal at all

bernabeu (SC) - Since this drain is in my workshop, it will get very little use, I'll increase the seal height to 3" to be safe. Thank you for sharing your expertise with me.

if the trap gets little use a cup of cooking oil or glycerin will minimize evaporation
if cooking oil, you are looking to 'layer'
if glycerin, fill
