Squeaky tap turned on, water runs, filling glass, tap turned off with drips, glass emptied into sink
Water turned on and wash hands under water, tap turn and water down drain
Water drain or small river
Water running into sink without a plug in, and water draining out
Water splash, with interior reverb
Shower running with drain and curtain.
Sink plug removed from sink, dry.
Bright and resonating synthesizer drain pipe loop
