Why does a new bathroom sink and drain with metal pipe make a gurgling sound and drain slowly when it is not clogged and the old sink and drain with PVC pipe did not gurgle and was not slow?
I'm going to guess the old sink was porcelain or cast iron and the new one is cultured marble? If that's the case, the old one had an over flow hole at the top of the bowl so that is wouldn't over flow. That was the vent for the sink. Cultured marble ones don't so the water is trying to go down against air pressure. If this is the case, it can be fixed or at least helped. Message me back for the details.

When you open a sink drain or flush a toilet, a head of waterenters the waste pipe. Since it fills the pipe, the water pushesair in front of it and creates a vacuum behind. Th…e vacuum exertsconsiderable internal force on the pipes, and unless you provide avent so more air can come in and fill it, the air will enterthrough any available opening -- usually a sink, shower or tubP-trap. The gurgling sound you hear from your sink is the sound ofair rushing past the water standing in the sink or in the bottom ofthe trap. That gurgling sound in your sink means there is an issue with theair in the drain pipes. Air normally is supplied through the vents,so either the vents are blocked, or they weren't correctlyinstalled. If the gurgling happens only when you use the sink, youprobably should focus on the sink vents, but if it happens when youflush a toilet or drain the tub, you need to examine the entirevent system.If the gurgling happens only when you drain the sink,there's probably a problem with the venting for that sink. The ventmay not have been installed the correct distance from the P-trap,or it may be blocked. Immediately call A-General plumbing companyto resolve the issue.
very simple, your drain that is gurgling is not vented properly. when the toilet is flushed, it is a large amount of water going down the stack at once. that sudden void creat…es a vacuum. it will pull air from the closest points possible. in this case, your gurgling sing or tub. if the tub and sink were vented, the air would be pulled from the vent stack, rather than the trap. hope this helps. I think this answer is incomplete. The drain can also gurgle due to a blockage down the line. Check to see if water is comming up anywhere when you run lots of water, if so call a plumber to snake the drain. 99% of the time, it's related to venting. Most drain blockages will cause drains to empty slowly but not gurgling. The source of the vent problem can vary, but the most common are that the vent was never installed, or the vent is plugged from something that entered from the top (bird, animal, ash, leaves, dirt, snow, etc.), or the vent is plugged by something that entered from the bottom (leftover material from a backed-up septic/sewer line). All are pretty easy and cheap to fix yourself but it can be a little messy (and smelly). Keep an old towel handy and wash your hands when done ;-)
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 . 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
You have a particle stoppage down stream or poor venting
Use a piece of equipment called a snake.
When piping in a bathroom with sink drain toilet and shower and the vent is located under the sink do you pipe in the vent with the sink drain?
If the vent pipe is below the flood level of a fixture you just defeated the purpose of the vent entirely
There is a blockage in your main sewerline. Odds are you have a problem wth either your vent pipe being to small or not located in the proper position to vent the waste line.… What I would suggest is installing a vent pipe on the sink if there is not one already. Another option is to buy one of those pop-vents that actually goes under the sink or install a vent at the toilet. When you get that gurgling sound it is because the Drain pipe is not pulling in air. It is creating a vacuum an the vacuum pulls on the line and the toilet will gurgle and let in enough air to compensate.
\nThere is a slight blockage in your sewer line which is creating air pockets, which eventually finds its way and escapes through the toilet and the sink.
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 dr…ains and gets carried away.
Yes a clogged VENT pipe can cause a sluggish drain
18" to center.
The installer was inept when it came to pipe supporting 101 .. He /she may have been sick that day and did not attend class Give them the benifit of the doubt
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 wo…uld 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.
Bath sink is not vented properly so it is using the kitchen sink as the vent.
This is most likely caused by a lack of venting on either your washing machine drain or sink. The gurgling noise you hear is actually air getting drawn through the water in t…he sinks trap as the washing machine water drains past the sink drain. Both the sink and washing machine should be checked for venting issues by a licensed plumber.
