Step 1: Removing the Old Drain Assembly
Begin by dismantling the old drain assembly from the top down. Employ pliers to carefully unscrew any stubborn slip nuts. This dismantling process is crucial for smooth replacement.
Step 2: Attaching the New Tail Piece
For kitchen sinks, insert the tailpiece washer into the flared end and fasten the slip nut onto the sink strainer. Should you possess a double basin sink, utilize a tee fitting to connect both tail pieces.
Initially, attach the fitting with slip washers and nuts. Enhance the seal with pipe lubricant on the slip washer for a secure fit.
Step 3: Connecting the Trap Arm
Affix the trap arm to the drain stub out. Assemble the slip nut and washer, ensuring the beveled side of the washer faces upwards. Subsequently, attach the trap bend to the trap arm using slip nuts and washers.
Employ slip joint pliers to cautiously tighten all the nuts, avoiding over-tightening that could lead to cracks.
Step 4: Testing for Leaks
With the new P-trap in place, it’s time to turn on the water and check for leaks. This step is pivotal to guaranteeing the success of your replacement endeavor.
By adhering to these steps, you’ll have successfully replaced your P-trap, restoring your sink’s functionality and preventing potential leaks. Remember, proper maintenance goes a long way in prolonging the life of your plumbing system.
