Weld-on 795 question

[cvrle1]

Hello

I have read few contradcting reports on weld-on 795 on couple of different reefing boards, so just wanted to see if I can get some more info on this issue.

Some people have said that weld-on 795 is not safe for aquarium plumbing, while others said that it is. I will be using flex PVC and was told that cement for flex and regular PVC is not the same and that I have to use 795.

Any help would be great cause I will be doing my plumbing today

TIA
