Kitchen plumbing help


Hi
My kitchen sink is not draining. It is pooling very quickly even after I empty the p trap. Please see pictures. The sink is on an island.
Could this be a clog or air vent problem. It was not like this before. I did try plunging it a few times. All the other drains on the house is working fine.

The last 2 pictures show how much water I dump in the sink before it pools to the sink bottom. I started with a full bottle on water and the remainder is shown.

Thanks

Re: Kitchen plumbing help


Remove the trap from the wall and snake the line.

Why do you have an old garbage disposer laying in the cabinet.

Re: Kitchen plumbing help


Tried that with 25 foot snake... still no good.

The garbage disposal will be reinstalled.

Re: Kitchen plumbing help


You need a longer and larger rodder----can you see the piping in the basement?

Re: Kitchen plumbing help


I'm no plumber, but if it is backing up that quickly, I'm definitely suspecting the vent pipe. If the branch vent is not properly sloped, maybe you got some water trapped in there and it is vapor locking. That would also explain why it used to work. A snake would go right through that and not solve your problem.

I'd try a wet/dry vac first. Sometimes I get lucky with that. If that doesn't work, try blowing it out with some compressed air (or just the exhaust port on your wet/dry vac). Just be careful that you don't blow the nasty water out of all the other traps in the house and make a big mess.

Tap on the pipes. A pipe full of water sounds different from an empty one.

If the other drains in the house are working, snaking the stack from the roof probably won't help. A real clog in the branch vent seems unlikely because I can't imagine how anything would get in there. But if so, you might have to cut the pipe and snake the branch vent. Even that is not a big deal at this point since you already have the wall opened up.

If my suspicion is right about the reverse slope of the branch vent, you might be best off just capping off the pipe and install an air admittance valve instead of an external vent. I have never used one, but I know there is such a thing and it might be the way to go if you just have to vent that one sink. Much easier than ripping out the whole ceiling and trying to change the slope of that pipe.

Re: Kitchen plumbing help


Basement is sheet rocked but I am ready to cut it open. I just need some insight before I go ahead with it.

Re: Kitchen plumbing help


Problem is NOT a vent pipe. Problem is a clogged pipe. No need to remove any sheetrock anywhere. Access drain pipe from stub out from wall. Use the correct snake, not a 25 foot light duty bulb snake. This is all just a very common kitchen sink drain line clog.

Re: Kitchen plumbing help


An island vent will have a foot vent running horizontal in your basement ceiling. When it come through the floor there will be a cleanout. Look around all the walls near the island for that clean out then snake from there.


If the vent is clogged this should open it.
This is what you might have- if plumbed correctly, you should have a wall clean out at the base of the vent stack

Re: Kitchen plumbing help


I opened up the basement ceiling. And i am noticing that the two black pipes going down into the basement intersect at a y connection. Apparently there is no clean out present. I also don't see the vent pipe there either. Please see pic and help.

Re: Kitchen plumbing help


Ok, so it's not plumbed the way I do islands.
Go get a bigger, longer power snake and keep working it from the sink. You've probably did more drywall damage than necessary. Time to get serious on a good cable, perhaps even call in a pro

Re: Kitchen plumbing help


I used an auger 25' x 1/4" power by drill machine. That did NOT work. Then I called a plumber and he did the same thing - no dice... but had too pay 75 bucks.

For a 50' auger I'm able to get 1/2 in. x 50 ft. Drain Auger from HD.

If there are other types I can get please advise. Otherwise I'll go with 50 footer above and if that doesn't work...... I may have to endup spending big bucks for a revamp...

The problem is not the length of the cable, it is the type. The snakes you and your "plumber" have used are going through the clog and the clog is closing up again when the cable is removed. I am disappointed your "plumber" showed no sign of having a clue about how to open a kitchen sink drain clog. TheEplumber is a master at all things plumbing related. Follow his advice and you will be victorious over your clog.

Re: Kitchen plumbing help


Just an update to the thread... I did use the 50' x 1/2" auger from Home Depot and open up the clog. First I tried from the sink side... Unsuccessful.
Then I opened up the drywall in the basement to access the clean out for the kitchen drain. After some struggling with the coil the clog surrendered.
Thanks for all the suggestions.

Re: Kitchen plumbing help


Good job! When you close the ceiling back , make an access or extend the cleanout for the future.
FYI- The drain shop I worked for used 3/8 cables on kitchens. 1/4" cables on tubs

Re: Kitchen plumbing help


Interesting. Why does the diameter of the cable matter. I always figured the head did all the cleaning.
