#1. You Can Sharpen The Blades In Your Garbage Disposal With Ice Cubes. There is no need to do anything to sharpen the blades in your garbage disposal because there are no blades in a garbage disposal. Garbage disposals have grinders called impellers. Garbage disposals do not have sharp blades like knives. The impellers grind solid garbage into liquid as they spin. You should never put hard things in your garbage disposal like ice, bones, or corn cobs. You can damage your garbage disposal doing that.
#2. You Can Save Money And Water By Putting A Brick in Your Toilet Tank. This is another myth that can damage your plumbing. You already have a low-flush toilet. They are now required in California. You should do nothing to further reduce the amount of water per flush. Furthermore, bricks deteriorate under water. Chips of the brick will eventually break off and can clog or damage the flush mechanism.
#3. You Can Flush Grease With The Hot Water Running. Yes, you can flush grease down your sink with hot water running, but then the grease will congeal in the pipes below and clog up all your drains. You should never flush grease.
#4. Flushable Wipes. You should never flush ‘flushable wipes.’ They should go in the garbage can. Flushable wipes do not dissolve in water like toilet paper. Flushable wipes do incredible amount of damage every year to plumbing and sewage treatment plants.
