Can I run my drain line to a sewer/septic?
Yes. These systems can be ran to your sewer or septic line and is typically the recommended
place to run the drain. Most concerns are related to the amount of water going down the
drain, and a properly designed septic/sewer system will not have a problem handling it.
Studies have also shown that concerns over salt in the wastewater affecting septic systems
are unfounded and not a problem.
