Hi everyone! - We bought a new house two years ago in North Texas that has a sink built in to the kitchen island. Shortly after moving in, we were hit with a strong odor coming from the kitchen island, and when we pulled the dishwasher out to look behind the sink area, we saw that the bow vent had been cut off and the sewer lines left open, we assumed, by the cabinet company who installed the island - apparently the bow vent was too tall for the cabinetry, so they cut it off! The plumbers associated with the builder came out and capped off both sides where the cuts occurred. However, we still get that sewage odor when opening the cabinet doors directly under the sink area. Interestingly, if we pull the dishwasher out and smell back where the capped repair was done, no odor. Another group of plumbers the builder is now using after they fired the other ones came out and smoke tested it for leaks, none found. We were told to dump coffee grounds under the cabinets and that would take care of the odor. I tried this and everything else under the sun to remove the odor, and it is still there. I do not believe that the wood cabinetry has just retained the bad smell, as every single cabinet door interior on the large island smelled awful when the leak was active, but as soon as it was fixed, no hint of the odor in any of the other cabinet door/drawer areas on the island. The plumbers have shrugged it off, saying if it was smoke tested and is not leaking still, there is no problem, it just smells, and that is unfortunate. My concern is I believe the bow vent design at the top of this fixture was there for a reason, and if it was cut off, it may not be venting properly, causing the smell to still occur. I am going to pull the dishwasher out again and see if I can photograph the repair. Any advice? Thanks for listening!
