Drum Trap Replacement
Hey guys -
I have a 2nd floor shower that has a drum trap that is now leaking. I have the ceiling on the 1st floor opened underneath this and an access panel behind the tub on the 2nd floor. I want to remove the drum trap and replace with a p-trap but have a few issues:
1) The exit line of the trap ties into the run from the toilet and then into the main stack. My problem is that the exit line from the trap goes over the run from the toilet and does a 180 loop and ties into the opposite side of the toilet line. The loop into the toilet line is one solid piece, no fittings. The line was bent to shape to make the connection.
2) There appears to be a 2nd exit line coming from the trap which looks like it ties into the main stack. I am guessing / hoping it is a vent? The research I have done on these types of traps led me to believe that these did not have vents. I know to replace with a p-trap the line needs to be vented. (don't have the time to run a separate dedicated vent)
So I guess my question is, assuming the line is vented, can I add the p-trap and go over the toilet line, do a 180 and tie back in? I know the "simple" solution would be to replace all lines to the stack but that really isn't an option at this point.
Thanks for the input and hopefully you can translate my babbling!
Also, I don't have a pic of this mess!
