Kitchen Sink PVC Drain Question

[cover]

I've been having a difficult time in getting a new PVC P-trap assembly leak-free under my kitchen sink. I think part of the issue as I try to transition from metal components was using pipe dope on the PVC fittings as one might do with metal components. I intend to strip out and try to get into PVC and given PVC is inexpensive enough, go back in with new parts and no pipe dope.

One big question I have is the transition fitting that connects the trap to the steel pipe in the wall (attached image). For PVC, can I use the existing steel fitting or should I remove it and install a special PVC fitting in its place? Any special nut and plastic compression sleeve or just a standard plastic nut and compression tapered sleeve? Access is pretty tight so I thought I'd leave it if possible but eliminating leaks is of course, most important.

TIA

I would get rid of that adapter and just go with a fernco. If the galvanized coming out of the wall is 1-1/2 you can use a DTC110 also if you are using a tubular trap as opposed to a regular sch40.

Thanks SHEPLMBR. Here'a pic of the same thing that served me well for a number of years but this time, it appears the rubber gaskets (sleeves?) aren't holding up at the yellow arrow nut connection areas.

This mess got started when I tried to snake a drain issue and poked a hole in the old tubular trap for a problem I still have on the other side of the wall (still a plugging issue) so I'll be snaking the other side of the wall and then working this trap area over to make leak-free soon. Also, the trap didn't seem to leak until I followed the recommendation of many, to pour boiling water down my drain to clear the plugged drain.

Everything under the sink is new now and I have enough money in it where I HOPE to just wipe pipe joint compound off and re-use everything, if that would be possible. Otherwise I was thinking new and PVC fittings, just to save in the replacement costs the second time around. Thoughts?

Yeah if you are gonna go tubular use the pvc tubular. That's just my preference. Others might think otherwise

I would get rid of that horizontal accordion pipe you have.

Sorry to seem ignorant but what is a "pvc tubular" trap? Something different than what my local Home Depot carries for pvc traps ?

PVC tubular.

PVC solvent sch 40.

PVC sch 40 with union.

so this image is 'tubular' type PVC? sorry but I'm getting a bunch of black squares on this thread so am a little unclear.

Also... Hate to be a pain but being a plumber, can you give me any pointers on removing the cleanout plug on the other side of the wall? The issue is the cast plug is recessed into the wall (sheet rocked with a cutout for the plug). The plug head is square and 1-1/4" across, side to side. I'm thinking a whatever size socket or box end wrench might fit on the head. My pipe wrenches won't fit because of the sheet rock.

Might be able to try a basin wrench. Have had to do that before.

I was thinking maybe some square socket for example. 1-1/4" span across and no way to get a pipe wrench on it.

There's no way to get a pipe wrench on it without removing sheet rock. I was hoping to find a socket maybe - thanks

Sorry - double post. Didn't think the one off my phone went through.

 

[SHEPLMBR]

I have used the basin wrench on them before.
But here ya go.
