How to Disassemble a Sink Trap to Retrieve a Lost Ring
Losing a ring down the drain is a common and distressing household mishap. Before resigning yourself to loss, know that the sink's P-trap-the curved pipe beneath your basin-is designed to hold water and block sewer gases, but it also acts as the first catch point for small objects. With careful disassembly, you can often recover your lost item. This guide provides a safe, step-by-step method for taking apart your sink trap.
Essential Precautions and Tools
Before you begin, understand that work under a sink involves potential hazards. You will encounter dirty water, possible mold, and sharp metal edges. Prepare accordingly.
- Safety Gear: Wear rubber gloves and eye protection. Have old towels or a bucket ready to catch water.
- Tools: You will typically need adjustable wrenches or a basin wrench, and possibly channel-lock pliers. Have a screwdriver handy if your trap uses slip-joint nuts.
- Workspace: Clear the area under the sink completely. Lay down cardboard or a thick towel to protect cabinet floors and kneel on.
Warning: If your home has older galvanized steel pipes, they may be corroded and difficult to turn. Excessive force can break the pipe. If you encounter significant resistance, stop and consider calling a professional plumber.
Step-by-Step Disassembly
- Shut Off the Water: Locate the shut-off valves on the hot and cold water supply lines under the sink. Turn them clockwise until tight. Open the faucet to relieve any remaining pressure and drain residual water from the lines.
- Place Your Drain Catch: Position your bucket or large bowl directly beneath the P-trap's lower section. Even with valves shut, water will be trapped in the curve of the pipe.
- Loosen the Slip-Joint Nuts: The P-trap is held by two large hexagonal nuts (slip-joints). The upper nut connects the trap to the sink's tailpiece (the pipe coming down from the drain). The lower nut connects the trap to the wall or floor drain pipe. Using your wrench, turn both nuts counter-clockwise to loosen them. They may unscrew by hand once loose. Support the trap with your other hand as the last nut comes off.
- Remove the Trap: Carefully lower the trap. Expect a gush of dirty, smelly water into your bucket. Once drained, inspect the inside of the curved pipe for your ring. It is very likely sitting in the first bend.
- Retrieve the Item: If the ring is visible, use your fingers or a flexible retrieval tool (like a bent coat hanger with a small hook) to hook and pull it out.
- Reassembly: Once retrieved, clean the inside of the trap with a bottle brush. Check the rubber slip-joint washers for wear. Reattach the trap, hand-tightening the nuts first, then giving each a gentle quarter-turn with the wrench. Do not overtighten. Turn your water supply back on and check for leaks.
