How do you fix a slow draining sink when a plumber's snake does not find a clog and there is a loud gurgling noise when water finally drains from the sink?

Answer:

Answer

If there is a loud gurgling noise, it may indicate that the vent is blocked/clogged, and the water in the trap is getting siphoned back down the drain as the water drains...

start at the trap at sink remove it to clean. then if not that maybe snake not reaching the clog longer snake may be needed
