01
Why the pipe objects
Paint can coat plumbing and may contain ingredients that should not enter wastewater or septic systems.
02
Do this instead
Keep it in its labeled container and use a local paint recycling or household hazardous-waste program.
03
Already did it?
Do not mix in cleaners or solvents. Ventilate the area, keep people and pets away from the spill and contact your local wastewater or hazardous-waste authority for product-specific guidance.
