To install a sink, ensure the opening in your vanity is the right size, then insert the sink. Install the locknuts underneath, starting with the center ones and moving outward. Tighten them down, then apply a bead of latex caulking around the sink's edge. Clean up excess caulk with water and a sponge.

It sounds like you may have a clogged drain, likely due to a buildup of grease, food particles, and soap scum. Professional cleaning is recommended to clear the blockage. Regular treatment with a product like Pipe Shield® can help prevent future buildup and extend the time between cleanings.

It sounds like the sewer smell when using your dishwasher could be due to a dirty filter, a blockage in the vent or drain pipes, or buildup of food particles. Here's what you can do: Clean the dishwasher filter: Remove the drain filter from the bottom of the dishwasher and wash it with soap and warm water. Use a bristled cleaning brush if needed to remove any buildup. Check for blockages: Inspect the vents and drain pipes for any blockages. If you suspect a clogged vent on the roof, it may require professional assistance to clear. Run a cleaning cycle: After cleaning the filter and checking for blockages, run a cleaning cycle in the dishwasher to help eliminate any remaining odors. If the smell persists, it's best to contact a professional plumber, like City Plumbing pro, to further assess and resolve the issue.
