What would cause a sink To gurgle?

Answer 1

When you open a sink drain or flush a toilet, a head of water enters the waste pipe. Since it fills the pipe, the water pushes air in front of it and creates a vacuum behind. The vacuum exerts considerable internal force on the pipes, and unless you provide a vent so more air can come in and fill it, the air will enter through any available opening -- usually a sink, shower or tub P-trap. The gurgling sound you hear from your sink is the sound of air rushing past the water standing in the sink or in the bottom of the trap.

That gurgling sound in your sink means there is an issue with the air in the drain pipes. Air normally is supplied through the vents, so either the vents are blocked, or they weren't correctly installed. If the gurgling happens only when you use the sink, you probably should focus on the sink vents, but if it happens when you flush a toilet or drain the tub, you need to examine the entire vent system.If the gurgling happens only when you drain the sink, there's probably a problem with the venting for that sink. The vent may not have been installed the correct distance from the P-trap, or it may be blocked. Immediately call A-General Plumbing company to resolve the issue.

Answer 2

because the little bit of excess water left in the simk is going down the drain and it makes a loud sound because there isn't much water and it echos when it falls into the drains and gets carried away.

Answer 3

It's like the expanding ripples you see in a pond when you toss a pebble in. Every drain in your house leads to the same exit path - so to that extent, they are all interconnected. A "ripple" of the water going into the waste line from the toilet is heard as a fainter echo (and slight pressure change) in the gurgle of the kitchen sink. It is perfectly normal.

Answer 4

If for some reason, there is a horizontal section of pipe for this drain/vent, you may have a situation where the pipe allows water to stay in one section like a trap. This would cause gurgling for the sink below this water stoppage, but allow water from the above sink to drain without issue. Once these situations are resolved, you will hear no gurgles.

Answer 5

there may be a slight blockage in the sewer line

Answer 6

It would make that noise if something was clogging the drain pipe. You can call a local plumber or plumbing business.
