Gurgling sink

[Stargazer]

In my master bath we have two sinks and one seems to gurgle whenever it wants to. The other one has never done this. Our house was built 4 1/2 years ago. This has been going on for awhile now and needs to get fixed. Any help would be appreciated so I can possibly get it fixed without calling a plumber.

Gurgling when draining or filling?

Draining could be caused by a bad vent. Filling could be caused by an unsealed fitting.

Do you use both sinks the same amount? Some times if the sink isn't used much the trap will dry out and you can hear the other plumbing through it. If it gurgles when your not using it then it could be like Bigndn said a plugged vent or your main sewer line might be filled with water caused by a blocked inlet baffle on your septic tank. Check your main sewer cleanout before your tank (or street if you don't have a tank) and see if there is water setting in it.

It gurgles mostly when not in use, and even when it has not been used for a long time. It also has done it when draining. I don't think I've ever heard it gurgle when filling. How would I check to see if it is a bad vent? Where is the vent? I know that sounds stupid, but I know nothing about plumbing.

No, we hardly ever use it because it is so annoying to hear. It is loud. I'm not trying to sound stupid but is the main sewer cleanout a pipe? Because I do have two pipes in my front yard. One up by the house and one out by the street. Should I check them both?

Thanks both of you for your help. If I have to call a plumber I will but I would like to see if it is something simple that I can fix myself.

Bad vent is what it sounds like. Something might be caught inside.

 

[splitshot]

The vent will be either through the roof or under the sink.

 

[Stargazer]

So basically if it is a bad vent just clean it out and the gurgling goes away? That simple? I will also check the main sewer cleanout that was suggested above.

Thanks for the picture because like I said above I had no idea. I just checked, looks like I will be getting on the roof today.

4 1/2 years old, huh? I'd make the general send out the plumber to do his job right- on his dime.

We had major issues when building this house but that could be it's own 20+ page thread in chat.

I met the plumber the 2nd week we moved in because neither bathtub or the other sink (the good sink in the master bath) would hold water. And one of the toilets ran nonstop which still has problems. That might be my next thread in here.

 

[bogus one]

are you on a septic system or city?
Not that it matters

Is it a 2 story? If so, are these sinks on the 2nd level?

 

[Stargazer]

City and its a one level house.

 

[bogus one]

slab on grade?

 

[Stargazer]

Yes, it's a slab on grade.

As I said in PM

Get a plumber out to check it out and maybe run a camera

The pipe in the yard would be the one to check. It should have a threaded plug. Check to see if there is water standing in the pipe. It should be empty. The vent will be a pipe sticking though the roof. Just check to see if it's clear, somtimes it can get blocked by bug nest ot leaves.If there is water in your main some sewer companys will come out and clear the house trap for you.

Bogus One - with all the issues I had building my house that I described in that PM I sent you, I probably do need to call a plumber. I'm going to try these two things first to save some money if I can. They seem easy enough that even I, the nonplumber, could do.

I will check both pipes and get up on the roof and check my vent. Thanks for the info on the sewer companies as well.

You may very well need a plumber but ever if you hire it out you should know whats going on.

You are probably already familiar with the trap under the sink, a certain amount of water is suppose to be trapped there to make a seal to keep gases from the waste system from coming into the room. for this to work both sides of the trap need to be vented to the atmosphere, if the drain system is sealed when you pour a gallon of water down the drain a gallon of air has to come out somewhere, it will push past one of the traps making a gurgling sound, as the water exits the drain system a gallon of air must enter the drain, again without a vent it will push past a trap making a gurgling sound.


Are the two sinks next to each other? you would think they would be plumbed together like a double kitchen sink each sharing a single trap,


What do you see in the cabinet under the sinks?
