The area under the kitchen sink is more than just storage; it's the heart of the kitchen, housing the main plumbing and drain lines. Avoid installing a water filter too close to the disposal, as the water filter tank can put excessive pressure on the plumbing drain, especially if you use a lot of cleaning products. Always store cleaning products in another cabinet or on the area where you have a pull-out trash can. Replace the external portable trash can to make daily cleaning easier. Wet trash left overnight can lead to mold and mildew growth, polluting the air in your home. Keep this area clean for a healthier environment.
