Question:<\/strong><\/p>\n

I recently installed a bathtub with an overflow to a santee<\/a>, but the gasket isn\u2019t sealing properly. I\u2019ve installed this exact setup twice before without issues. I followed the instructions, placing the thick part of the gasket at the top. The pipe from the overflow to the santee is slightly off plumb, but it shouldn\u2019t be an issue. Could this be a poorly shaped gasket?<\/em><\/p>\n

Answer:<\/strong><\/p>\n

It sounds like the main issue could be a defective or poorly shaped gasket<\/strong>, despite your careful installation. Even minor imperfections in a gasket can prevent a proper seal, leading to leaks. Here\u2019s what you can do to troubleshoot:<\/p>\n

    \n
  1. \n

    Inspect the gasket<\/strong>: Even if you\u2019re using the same model, manufacturing defects can occur. Check the gasket carefully to see if there\u2019s any visible damage or irregularity that could prevent it from sealing correctly.<\/p>\n<\/li>\n

  2. \n

    Ensure proper installation<\/strong>: While you mentioned following the instructions, double-check the orientation of the gasket. The thicker part should go on top, as you\u2019ve already done. If the gasket is misaligned, it could cause the issue.<\/p>\n<\/li>\n

  3. \n

    Check alignment<\/strong>: Though you mentioned that the pipe is only a hair off plumb, even small misalignments can impact the gasket\u2019s ability to seal. If it\u2019s slightly off, consider adjusting it to see if the seal improves.<\/p>\n<\/li>\n

  4. \n

    Clean and lubricate<\/strong>: Sometimes, dirt or debris can get caught in the gasket, preventing it from sealing properly. Clean both the surface of the gasket and the surrounding area. A small amount of plumber\u2019s grease on the gasket might help it sit better.<\/p>\n<\/li>\n

  5. \n

    Try a new gasket<\/strong>: If all else fails, replacing the gasket with a new one (from a reputable brand) might be the solution. The one you\u2019re using may be simply defective.<\/p>\n<\/li>\n<\/ol>\n

    By taking these steps, you can ensure that your bathtub overflow is sealed properly, preventing leaks and potential water damage.<\/p>\n
