How to Clean Pipes Under a Sink?

Cleaning pipes under a sink typically involves removing clogs and buildup. Here's a breakdown of how to do it:

Initial Steps

Before you start, place a bucket under the pipes to catch any water and debris. This prevents a mess.

Several methods can be used, depending on the nature of the clog:

Hot Water: Sometimes, simply pouring very hot (but not boiling, as this can damage some pipes) water down the drain can dissolve minor clogs.
Plunging: A standard cup plunger can be effective for minor blockages. Make sure there's enough water in the sink to cover the cup of the plunger to create a good seal.
Baking Soda and Vinegar: Pour about one cup of baking soda down the drain, followed by one cup of vinegar. Let it fizz for about 30 minutes, then flush with hot water.
Hot Water and Vinegar: According to existing information, a mixture of very hot water and vinegar can help melt and remove grease. Let this mixture work for a few minutes, then use a plunger. You may have to repeat this more than once.

If the above methods fail, you may need to disassemble the P-trap, the curved section of pipe under the sink.

Prepare: Place a bucket underneath the P-trap.
Loosen Connections: Carefully loosen the slip nuts that connect the P-trap to the drain pipes. You may need slip-joint pliers.
Remove the P-Trap: Once loose, carefully remove the P-trap. A lot of gunk will likely come out, so be prepared.
Clean the P-Trap: Clean out the P-trap thoroughly. Use a wire or old toothbrush to remove any buildup.
Reassemble: Reattach the P-trap, tightening the slip nuts securely but not overtightening.
Test: Run water to check for leaks. If there are leaks, tighten the connections further or replace the washers inside the slip nuts.

Plumbing Snake (Auger): For more stubborn clogs further down the drainpipe, a plumbing snake can be used to break up or retrieve the blockage.
Chemical Drain Cleaners: Use these as a last resort and with caution, as they can damage pipes and are harmful to the environment. Always follow the manufacturer's instructions carefully.
Prevention: Prevent future clogs by avoiding pouring grease down the drain, using a drain strainer to catch hair and food particles, and periodically flushing the drain with hot water.
