Prevent drain blockage—these traps have a reusable basket to catch debris, such as metal chips and stones, before it enters your sewage system. For quick disposal, unthread the thumb screws by hand to access and remove the reusable basket. When the tank is closed, a gasket seals in odors.

Install these traps under your sink as a P-trap replacement. The tank and basket are made of polypropylene, so they resist acids and other chemicals.

Get ahead of your water heater maintenance—these traps catch debris from natural gas lines before it can enter the tank. Also called a drip leg, these traps are often required by building standards. They’re plated in zinc, so they’re mildly corrosion resistant.

Install them after your shutoff valve and as close to the water heater inlet as possible. To empty the trap, unscrew the cap and dispose of any debris.

For safe and legal disposal of corrosive chemicals, these tanks neutralize acid waste before it drains into sewer systems. Fill them with limestone chips (sold separately), which chemically react with waste to reduce its acidity. Often used in labs, these tanks rest on a solid surface below your sink. The inlet attaches to your sink drain where a P-trap would go, and the outlet threads into your drain pipe. These tanks are made of polyethylene to withstand prolonged contact with harsh chemicals.

Choosing a tank size involves several factors, including how much waste you generate and the types of chemicals you plan to treat. For effective neutralization, waste should spend three hours in your tank before exiting via gravity flow. Select a tank that is greater in size than the volume of chemicals you plan to dispose of in a three-hour period.
