This should be obvious, but you would be surprised to learn just how many people rinse soiled motor oil pans and buckets in the kitchen or garage sink. Some people are even used to dumping used motor oil down the drain! This is one of the biggest no-no’s on the Blake type drains. Motor oil and other automotive chemicals can cause blockages and backups in your water supply pipes. And according to the EPA, just one quart can contaminate over 2 million gallons of local drinking water.
Toxic Products and Cleaners
Common household products can contain dangerous chemicals, so they should clearly never be dumped back into the sink drain since it can contaminate local water supplies. This includes acetone, rubbing alcohol, paint, paint thinners, lacquers, turpentine, solvent-based cleaners, pesticides, fertilizers, and anything else with toxic chemicals or agents. Look up how to properly dispose toxic chemicals and cleaners within your community.
We use so much water that most of what’s poured down the sink drain winds up back into our drinking water supplies. This explains why medicine should never be dumped down the sink drain either. Birth control, antibiotics, penicillin, and other medications can contaminate drinking water and put others at risk. Fortunately, many pharmacies accept unused or expired medication at no cost to you.
Cooking Oils and Grease
You may be tempted to rinse that bacon grease down the drain, but it is quite damaging to you inner plumbing systems. Not only can it contaminate drinking water, it can clog or corrode your water supply pipes, reduce decomposition of food scraps, and attract pests. This can eventually lead to costly repairs and replacements, and long periods of inconvenience. Avoid pouring lard, butter, oil, and grease down the drain. Preserve it in glass jars instead, and then toss it in the trash.
Fibrous Food Scraps
To protect your garbage disposal, be sure you are not dumping fibrous or hard food scraps down the drain. This can be damaging to the blades, bending, weakening, or dulling them over time. And some foods expand with water, causing blockages and clogs. Scraps to avoid include animal bones, citrus peels, corn husks, potato skins, peanut shells, eggshells, coffee grounds, pasta, and even cereal.
