If you have a septic system on your property, then it's important that you have the tank cleaned out by a professional from time to time. Occasional cleanings ensure that the system does not overfill and operates at an optimal level. Of course, to cut down on your maintenance expenses, you don't want to clean the tank more often than necessary. Keeping cleanings to a minimum means you need to avoid certain practices that can interfere with the system's operation. Here are some mistakes people make that lead to more frequent cleanings. 

Scraps 

Your septic tank holds a variety of microorganisms, such as bacteria, that break down waste and prevent the tank from overfilling. If you put certain types of waste into the tank, this process is less effective and the tank can overfill. One of the most important waste materials to keep out of your tank is food scraps. Egg shell, coffee grinds, vegetable oil and other kitchen waste is harmful and should be disposed of elsewhere. 

One good idea is to start a compost pile. This gives you the perfect place to toss your food scraps and other kitchen waste, as well as providing an excellent fertilizer for your garden. 

Chemicals 

Various types of chemical liquids should also be kept out of your septic tank. Although some commercial cleaners and disinfectants might not present a problem if used in moderation, others should never be placed in your drains. This includes anti-freeze, paint, paint thinner, gasoline, motor oils and pesticides. Any of these can interfere with the breakdown of waste in the tank and cause it to fill up more quickly than normal. 

Hot Tubs 

If you have a hot tub or whirlpool, then it's very important that you do not empty them into the septic tank. The amount of water could easily be too much for the system to handle. Rather than taking this risk, drain your whirlpool or hot tub onto an area of your property that is well away from the septic system. The disposal of this type of waste water could be regulated by your municipality, so check the relevant local laws before taking any action. 

Experts suggest having your septic tank cleaned out about every three to five years to keep everything running smoothly. To avoid having to do more frequently, don't commit these mistakes that place extra stress on your system. For more information, contact a local septic tank service.
