How often should my tank be pumped? Is there a difference between pumping and cleaning?

As a rule, tanks should be checked for solids buildup every year and pumped every three years to five years, more often if you have a garbage disposal. It is best not to wait until the plumbing system begins to back up in your home. If solids overflow from the tank, some very expensive damage can be done to the soil absorption system. In practice, however, how often solids should be removed depends on the lifestyle of the family using the system and the size of the tank. For example, a garbage disposal can result in a rapid buildup of solids. Many homeowners have installed risers with child-proof caps on their tanks to simplify removal of solids and they routinely have their tanks cleaned every three to five years. When choosing a company to remove solids from your tank, ask if they thoroughly clean the tank and remove all solids. It is not very useful to just pump the liquids without removing the solids from the tank. Reputable companies flush removed liquids back into the tank to thoroughly agitate and remove settled solids. In addition, they check the baffles on the tank to make sure they are functional and clean the tank’s effluent filter (if installed). If your tank has an effluent filter installed, inspect it via the riser every 6-12 months for fouling. If buildup on the filter becomes substantial, have the tank cleaned. A properly functioning tank effluent filter protects the soil absorption field much more effectively than a baffle. If your tank does not currently have one, consider installing one the next time you have your tank cleaned.
