Using biodegradable products will help with the digestion of sewage; the use of effluent and lint filters will help stop solids and non-biodegradable lint fibers from entering and clogging your drain field. Chemicals in everyday products can interfere with the optimal digestion of sewage. Avoid pouring bleach and harsh chemicals down your toilet and drains. Any material that cannot be broken down should not be poured into your drains or flushed down your toilets. Lint and hair can be easily removed before entering the septic system. Lint filters stop lint and hair and can be bought from any hardware store; they belong in each and every drain. If your washer does not have a lint filter, and your plumbing is behind your wall, have a canister lint filter attached to your washer. If your washer water gets drained through a pipe into your sink, you can attach a disposable mesh lint filter to the discharge pipe. A septic system professional should attach an effluent filter to the outlet pipe of your septic tank to stop solid from making their way into your drain field.
