Stop a leak under the sink

draft · verifying asked 185 ways distilled today
  1. 1

    Find where the water actually starts.

    Dry everything, lay paper towel, run the tap. The wet spot on the paper points at the joint.

  2. 2

    Hand-tighten the trap first.

    Most under-sink leaks are a loose slip nut on the U-bend. Hands only; tools crack plastic.

  3. 3

    Check the washer inside the joint.

    Unscrew the nut, look at the cone washer. Flattened or cracked means a one-euro replacement.

  4. 4

    Reseat and align before tightening.

    Pipes must meet straight. A nut forced over a crooked joint always weeps.

  5. 5

    Test with paper underneath.

    Full tap for a minute, then look at the paper. Dry paper is the only proof.

#1 becomes the Core. This atoma is young: submit a better distillation and take the seat.

No gear needed. Your pot, a timer and ice are enough. That is the point.
