Sometimes the smell comes from the drain itself, not the water. Pour a cup of baking soda down the sink, followed by a cup of vinegar. Let it fizz like a science fair volcano, then flush with hot water. If the smell disappears, you just cleaned a bacterial buildup in the drain—no magic required.
Also, check your dishwasher and washing machine. Old rubber hoses can trap bacteria and produce that eggy odor. Replacing them with new, high-quality hoses is cheap and takes ten minutes. Your laundry will thank you by not smelling like a swamp.
And hey, if you’re still smelling rotten eggs after all this, call a professional plumber. No shame in that—sometimes the bacteria are just that stubborn. But nine times out of ten, these fixes will save you money and keep your nose happy.
