    Remember when you were a kid and sang songs like:
        Here we go loopty loo
        Here we go loopty li
        Here we go loopty loo
        All on a Sunday morning.
    Not that I am against happy songs and a happy plumbers as we all need more happiness in this spinning orb. However, it seems as if some folks have the propensity to get a little too carried away and start drifting . . .
    The S-shaped trap AKA the S-bend was invented by Alexander Cummings in 1775 and was replaced by the introduction of the U-shaped trap by Thomas Crapper in 1880. FYI, Crapper did not invent the toilet, he just popularized it.
    Lest I digress, the S-trap is now banned in the United States and Canada. The purpose of the trap is to form a water seal and prevent sewer gasses from entering the home. The disadvantage of the s-trap is that it is not vented which allows water to be siphoned out of the trap, hence allowing sewer gas to flow back to the drain and into the house. Adding a another S-trap does not make the situation any better.
    The solution? Change the trap to a P-Trap and add an air admittance valve. EZ-PZ.

Good morning Michael. Just a few challenges with this setup, but all fixable. No real tradesman at work here.

Michael-I learned something new. Didn't know S-traps were banned and never heard of a U-trap but then again I am not a plumber. That is an unusual connection.

Good morning, Ronald Gombach . It is on a Saturday night. Seeing as it is Sunday morning, I took the creative license to change the words a tad . . .

Hi Michael.  Say it isn't so.  Crapper didn't invent the crapper.  Bummers.

Good morning Michael.  I've seen my fair share of plumbing under a sink but nothing like your photo today.

That looks more like someone trying to get over to the corner. It is possible that it vented through a common vent with something on the other side of the wall.

Top of the morning Michael.  I was wondering where in the world is this lyric leading?!   One glance at the picture explains all.  Good post and lead in.  Mark

The sheer majesty and symmetry of that wonderful installation sells me!

You wanting to put it in the Crapper (wasn't it Krapper?) is a bit harsh.
