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.
