Moving the kitchen sink P-trap on the Quantum JM31
The Quantum JM31 kitchen sink drain was poorly designed with the P-trap mounted directly under the sink and no slope on the output pipe. As a result, there is always water visible in the sink drain. We modified the drain to relocated the P-trap and the air admittance valve. We documented the project with a PDF file so other's could take advantage of our experience.
