Double Sink Clog -

Avoid pouring caustic liquid cleaners down your sink. They rely on intense exothermic reactions that can warp or melt plastic PVC pipes, corrode old metal plumbing, and fail to clear total blockages. Furthermore, if the chemical fails, you are left with a basin full of toxic, burning acid that makes mechanical repair highly hazardous.

The blockage resides inside the continuous waste tee, inside the P-trap, or further down the horizontal drain line inside the wall. 3. Plunging One Side Makes Water Shoot Up the Other Side double sink clog

The clog is downstream from where the two lines meet. Avoid pouring caustic liquid cleaners down your sink

Always turn on a strong stream of cold water before flipping your garbage disposal switch. Keep the water running for 15 seconds after the grinding sound stops to ensure the food particles are swept completely past the P-trap and into the main vertical stack. Cold water keeps fats solid so the disposal blades can chop them up effectively; hot water melts them, allowing them to coat the pipes further down the line. The blockage resides inside the continuous waste tee,

Place a standard cup plunger firmly over the clogged drain. Tilt it slightly to let air escape from the cup, ensuring a pure water-to-water seal.

If the cable locks up or bogs down, reverse the rotation slightly, pull back, and drive forward again.

The clog is below the waste tee junction (P-trap or wall line). 4. Foul Odors with Slow Drainage
