Hi. I'm removing an old laundry sink and couldn't get the drain tube out after loosening nut below, so I used a hacksaw to cut the 1 1/2 pipe that the drain tube attached to. Right now there's water in it , but the pipe is coming UP so nothing is getting out. Is this ok to leave for the weekend like this? Do I have to worry about sewer gas or anything? I'm going to remove all this and put in a modern p trap, etc. The plumber who was over for something else told me to leave the 1 1/2 white pipe in back and tie into that with my new p trap setup. He told me to cut basically right at the end of this setup on the right and use a 1/ 1/2 to 1 1/4 adapter. When I cut that pipe after the last bend there on the right is water going to come rushing out? I'm not cutting the white pipe in back, but a few inches BEFORE that of course to attach my adapter, etc. I assume that the large drain pipe that this goes into to the furthest right is the main house drain pipe for everything. The 1 1/2 pvc in back drains from another sink (which I'm doing over also) in back of this wall in a small basement bathroom area. So it's basically two sinks adjacent to each other that share the same drain pipe.

[attach]92475[/attach] Had a Culligan tech replace all but the RO membrane on my AC-30 RO system. Now there is a very slow leak where the tubing goes into the manifold (see attached picture). I have tried pushing the tubing in several times, no change, still leaking. Any suggestions? Is there an o-ring there that I need to change? I have not pulled the tubing out to inspect yet. I have a phone call into the Culligan office here but they're not super responsive... Thanks in advance for any help.
