GARBAGE DISPOSAL-YES OR NO?
Go easy on the garbage disposal. Using this doubles the rate of solids building up in the tank. Try composting as an alternative. A-1 Septic Service does not recommend using a garbage disposal.

DID YOU KNOW?
You should conserve water whenever possible. Large volumes over short periods will flush untreated wastes into the drain field. Space out heavy uses of water such as laundry and bathing.

IS IT SAFE TO FLUSH?
No cigarette butts, tissues, sanitary napkins, disposable diapers, coffee grounds, or cotton swabs. If it is not biodegradable it doesn't belong in the septic.

STOP! DON’T DUMP THAT GREASE DOWN YOUR DRAIN!
It’s the same as dumping your hard earned money down the drain! Grease can harden in the tank's scum layer and then build up and block the inlet or outlet of the tank. If you melt grease and pour it down the drain it may run through the septic tank, hardening and clogging the soil pores. Any of these could be very costly to take care of, so save your septic system as well as your wallet, and don’t dump grease down the drain!
