My 2018 320S has
standard P-Trap plumbing. I've never considered changing as the P-Trap makes a nice cabinet space divider for how I use that cabinet.
Since my first outing there has been an on-again, off-again water leak. Most frequently happening when a full sink is being drained. Early on the sink drain tailpipe to P-Tape joint was found to be the source**. So on most trips I try to remember to adjust/tighten the joint.
Well, I finally got around to lengthening the tailpipe by adding a
tailpipe extender, now the tailpipe mates deep into the P-Trap and the leak is gone.
It only
took me 6+ years to get around to it . . . **
seems factory got their dimensions wrong and tailpipe just engaged the P-Trap joint by a quarter inch.
someone placed the drain standpipe T-joint to low
