Here are some things (not a complete list) that should not ever go into the septic tanks and leaching fields!
Water from gutter or floor drains.
Non-Biodegradable Products - chemicals and solids (tampons, cigarette butts, condoms, or other similar items, hair,
bandages, rags, strings, coffee grounds or cereals).
Paper towels and handy wipes; no matter what the box or manufacturer, etc. says!
No anti-bacterial soaps - Biodegradable soaps only! Do not use what is called "biocompatible soaps".
Heavy or long-term use of Mr. Bubbles, spray toilet cleaner or any other excessively strong cleaner.
Water conditioning backwashes / discharge from water softener, & purifier, sanitizer or conditioners.
Dehumidifiers and air conditioner discharges.
Chlorine and chemicals in excess (1 part chlorine 5 parts of water is a good spray bacteria cleaner).
Hot tubs and jacuzzi discharges.
Water from excessive loads of laundry. Loads should be spaced out (one day of doing all laundry is a No No!).
Water from leaking fixtures including sneaky leaky toilets. Remember to dye test the toilet often to check for leaks in septic system.
Dirt and inert products (muddy clothes and vegetables should be dusted off before washing) this applies to
common senses in maintaining all types of septic systems.
Disposable baby wipes / diapers / hand and facial wipes - NO MATTER WHAT MANUFACTURER SAYS, DON’T PUT THEM IN; DISPOSE
OF THEM IN A GARBAGE CAN!
Hard toilet paper - use only soft toilet paper which will come closer to breaking down in your septic tanks than hard toilet paper.
Dead fish or small animals - REMEMBER, it’s a septic tank, not a cemetery.
Discharge from garbage disposals. If you must use a garbage disposal, limit
use to tiny pieces of food. Regular use of a garbage disposal will increase need
for pumping tanks by 20%.
Bath products or hair conditioners with heavy oils.
Latex, plastic or metallic objects - (If you haven’t, wouldn’t or couldn’t eat it - Don’t throw it in septic tank system!).
